Hello Magnolia - SPA

In this Tutorial we will learn how to use the Visual Single Page Application (SPA) Editor to build stunning websites with ReactJS and Angular.

Basic Form-based headless CMS systems are good for constrained and predefined content types. But to give marketers the ability to create articles, page structure or create their own custom landing pages or micro-sites, the Magnolia SPA Editor will accelerate your Marketer and free up your development capacity.

The Visual SPA Editor is bridging the gap between enterprise-level content management systems and SPA frontend development.

Check out Hello Magnolia - Headless to get started with some basics.

What are we going to build?

We are going to build a Travel Website SPA promoting travel packages.

In the previous tutorial we have built a basic Headless CMS Website. In this tutorial we will create an application, but enable the Marketer to visually change the SPA.

  • Marketers can add new navigation items

  • They can create new pages and arrange the content freely with a pre-defined list of Components.

SPA handles 1024x512

Prerequisites

  • Magnolia CLI and required development tools. The instructions are here.

Install the demo project

To jumpstart our project, we will install our demo project. The easiest way to do this is to clone our git repository.

  1. Create a directory named ``minimal-headless-spa-demos'' and cd to that directory.

    touch minimal-headless-spa-demos; cd minimal-headless-spa-demos;
  2. Clone the git repository.

    git clone -b minimal-headless-spa-demos https://git.magnolia-cms.com/scm/demos/minimal-headless-spa-demos.git

Install Magnolia

  1. Switch to the cloned project:

    cd minimal-headless-spa-demos
  2. Change directory to magnolia.

    cd magnolia
  3. Start magnolia.

    mgnl jumpstart
  4. Choose number 2 (magnolia-community-webapp)

    ? What Magnolia would you like to install?
      1) magnolia-empty-webapp
      2) magnolia-community-webapp (1)
      3) magnolia-community-demo-webapp
      4) magnolia-dx-core-webapp
      5) magnolia-dx-core-demo-webapp
      Answer: 2
    1 This one!

Once the installation is finished you will see an output similar to this on your console:

info Magnolia has been successfully setup for light development!
info You can now open a new terminal tab or window and start it up with the CLI command 'mgnl start'
info Magnolia will be ready after a few seconds at localhost:8080/magnoliaAuthor. Username and password is superuser
install magnolia cli

Before starting

Before you get going too far, pick up some handy configuration and sample images.

  1. From the magnolia directory, run:

    • Mac or Linux

    • Windows

    cp -rv ./_dev/content-to-bootstrap/* ./apache-tomcat/webapps/magnoliaAuthor/WEB-INF/bootstrap/common (1)
    xcopy ./_dev/content-to-bootstrap ./apache-tomcat/webapps/magnoliaAuthor/WEB-INF/bootstrap/common\ /E/H (1)
    1 This copies all files inside /magnolia/_dev/content-to-bootstrap into /magnolia/apache-tomcat/webapps/magnoliaAuthor/WEB-INF/bootstrap/common.
  2. Start Magnolia

    mgnl start

Install the SPA

We include a React, Angular & Vue example, just choose which one you want to use.

In your terminal, go to the actual frontend app directory (for React, Angular or Vue). Install the dependencies either with npm or yarn, and do your first build.

  • React

  • Angular

  • Vue

cd ../spa/react-minimal
npm install
npm run start
cd ../spa/angular-minimal
npm install
ng serve
cd ../spa/vue-minimal
npm install
npm run start

See It In Action

Let’s have a look at the running demo containing the starter content before we inspect the Starter Code. In the previous chapter, we have started Magnolia and built and started our SPA project.

Install demo content

To install the Demo Content follow these steps:

  • Open the Pages App in your browser.

  • Click Import action (You might need to scroll down in the action bar.)

  • For React: Select the file ./magnolia/_dev/content-to-import/website.react-minimal.yaml

  • For Angular: Select the file ./magnolia/_dev/content-to-import/website.angular-minimal.yaml

  • For Vue: Select the file ./magnolia/_dev/content-to-import/website.vue-minimal.yaml

Page Builder

In the Pages App, open the SPA Project by double clicking on react-minimal, angular-minimal or vue-minimal depending on which project you have installed.

Now you can see the React, Angular or Vue app rendered in the Magnolia Page Builder. Go-ahead and try to change the title or add an image.

Hooray

You are editing a SPA!

Inspect the Code

Let’s have a look how our demo project is structured:

03 spa component screenshot

The blue and green components are fixed components, the developer controls them and their position. The magenta components inside the Area Component are controlled and freely arranged (added, moved, deleted, etc.) by the marketer. The marketer uses the Page Editor to edit the SPA with components built and defined by the developer.

You can look at it as the developer putting `handles' and `knobs' on frontend components, so that marketers and content authors can move them around and tune them with custom content.

The green Page Component and Area Component are provided by Magnolia.

  • The Page Component is responsible for rendering the `top' frontend component, and preparing the Magnolia Page Editor.

  • The Area Component is mapping the content created by the marketer , to the components defined by the developer, in order to render them. You can define multiple area components on the same Page Component, and a component can have one or more areas of its own.

SPA block 1024x512

Light Modules

You can share code and components in multiple light modules.

Shared Light Module: spa-lm

The Magnolia templates and dialogs are the same no matter the front-end framework, so the demo project puts all the shared content in the ``spa-lm'' module.

cd magnolia/light-modules/spa-lm
Templates

Template definitions register the component with the Magnolia system. They also point to the Dialog definition.

cd templates/components
  • headline.yaml

  • image.yaml

  • paragraph.yaml

Dialogs

Dialog definitions provision the form that Marketers will use to tune and enter content. They define the fields and the names of the properties to be persisted.

cd ../../dialogs/components
  • headline.yaml

  • image.yaml

  • paragraph.yaml

Application Light Module

The actual SPA will be deployed to a front-end framework specific module.

We have defined two Page Templates, which the marketer will be able to include in our SPA in the page builder. In the page template you can define Areas and which components which will be available in that area.

  • React

  • Angular

  • Vue

cd ../../../react-minimal-lm;
cd templates/pages;
cd ../../../angular-minimal-lm;
cd templates/pages;
cd ../../../vue-minimal-lm;
cd templates/pages;

Have a look at

  • basic.yaml

  • contact.yaml

Frontend App Structure

Open your project in:

  • React

  • Angular

  • Vue

minimal-headless-spa-demos/spa/react-minimal/src
minimal-headless-spa-demos/spa/angular-minimal/src/app
minimal-headless-spa-demos/spa/vue-minimal/src

We have two categories of templates. Page and Components.

In our source directory we have two sub directories. Page (containing Layout Components) and Components.

  • Pages

    • Basic

    • Contact

  • Components

    • Navigation

    • Headline

    • Image

    • Text

magnolia.config.js

The componentMappings in this file are what the Magnolia JS libraries use to determine which SPA component to instantiate, based on the templateID (for example: spa-lm:components/paragraph) which is received in the JSON from the Magnolia endpoint.

  • React

  • Angular

  • Vue

import Basic from "./pages/Basic";
import Contact from "./pages/Contact";
import Headline from "./components/Headline";
import Image from "./components/Image";
import Paragraph from "./components/Paragraph";
import Expander from "./components/Expander";
import List from "./components/List";
import Item from "./components/Item";

const config = {
  componentMappings: {
    "react-minimal-lm:pages/basic": Basic,
    "react-minimal-lm:pages/contact": Contact,

    "spa-lm:components/headline": Headline,

    "spa-lm:components/paragraph": Paragraph,
    "spa-lm:components/expander": Expander,
    "spa-lm:components/list": List,
    "spa-lm:components/listItem": Item
  }
};

export default config;
import { BasicComponent } from "./app/pages/basic/basic.component";
import { ContactComponent } from "./app/pages/contact/contact.component";
import { HeadlineComponent } from "./app/components/headline/headline.component";
import { ListItemComponent } from "./app/components/list-item/list-item.component";
import { ListComponent } from "./app/components/list/list.component";
import { ParagraphComponent } from "./app/components/paragraph/paragraph.component";
import { ImageComponent } from "./app/components/image/image.component";
import { ExpanderComponent } from "./app/components/expander/expander.component";

export const config = {
  componentMapping: {
    "angular-minimal-lm:pages/basic": BasicComponent,
    "angular-minimal-lm:pages/contact": ContactComponent,

    "spa-lm:components/headline": HeadlineComponent,
    "spa-lm:components/list": ListComponent,
    "spa-lm:components/listItem": ListItemComponent,
    "spa-lm:components/paragraph": ParagraphComponent,
    "spa-lm:components/image": ImageComponent,
    "spa-lm:components/expander": ExpanderComponent
  }
};
import Basic from './pages/Basic';
import Contact from './pages/Contact';
import Image from './components/Image';
import Headline from './components/Headline';
import Paragraph from './components/Paragraph';

    'spa-lm:components/listItem': Item,
    'spa-lm:components/expander': Expander,
  },
};

export default config;

Frontend Components

Root Component / Bootstrap Component

The Root Component (App.js in React, root.component.ts / root.component.html in Angular, App.vue in Vue) is the main entry point of our app. it defines the page structure and routing.

The imports of the Magnolia JS lib: @magnolia/react-editor or @magnolia/angular-editor.
  • React

  • Angular

  • Vue

return (
    <BrowserRouter basename={base} forceRefresh={true}>

      <header>
        <Navigation />
      </header>

      <div className="container">
        <Switch>
          <Route path="/" component={PageLoader} />
        </Switch>
      </div>

      <footer>
        Integer posuere erat a ante venenatis dapibus posuere velit aliquet.
        <br />
        Copyright © 2020
      </footer>
    </BrowserRouter>
);

From /helpers/PageLoader.js:

import { EditablePage } from "@magnolia/react-editor";
import { EditorContextService } from '@magnolia/angular-editor';
<app-navigation ></app-navigation>

<editable-page [content]="content">
</editable-page>

<footer>
    Integer posuere erat a ante venenatis dapibus posuere velit aliquet.
    <br />
    Copyright © 2020
</footer>

In Vue js we define the routes in main.js.

main.js
import Vue from 'vue';
import VueRouter from 'vue-router';
import App from './App.vue';
import PageLoader from './helpers/PageLoader.vue';

Vue.config.productionTip = false;
Vue.use(VueRouter);

const router = new VueRouter({
  mode: 'history',
  base: '/magnoliaAuthor/vue-minimal',
  routes: [{ path: '*', component: PageLoader }],
});

new Vue({
  router,
  render: (h) => h(App),
}).$mount('#app');

The App.vue is loading the proper routes using the PageLoader Component defined in main.js using the standard router-view.

The main entry point App.vue is looking like this:

<template>
  <div id="app">
    <header>
      <Navigation />
    </header>
    <div class="container">
      <router-view :key="$route.fullPath"></router-view>
    </div>
    <footer>
      Integer posuere erat a ante venenatis dapibus posuere velit aliquet.
      <br />Copyright © 2020
    </footer>
  </div>
</template>

<script>
import Navigation from "./components/Navigation";

export default {
  name: "app",
  components: {
    Navigation
  }
};
</script>

<style>
@import "./App.css";
</style>

Page Component

The Page Component is defining the layout and the placement of the Area components. Let’s have a look at the Basic Page. The EditableArea is defining which conntent should be displayed.

In our case we have defined main and extras in our page template.
  • React

  • Angular

  • Vue

import React from 'react';
import { EditableArea } from '@magnolia/react-editor';

const Basic = props => {
  const { main, extras, title } = props;

  return (
    <div className="Basic">
      <div className="hint">[Basic Page]</div>
      <h1>{title || props.metadata['@name']}</h1>

      <main>
        <div className="hint">[Main Area]</div>
        {main && <EditableArea className="Area" content={main} />}
      </main>

      <div className="Extras" >
        <div className="hint">[Sercondary Area]</div>
        {extras && <EditableArea className="Area" content={extras} />}
      </div>
    </div>
  )
};

export default Basic;
<div class="Basic">
    <div class="hint">[Basic Page]</div>
    <h1>{{title || metadata['@name']}}</h1>

    <main>
        <div class="hint">[Main Area]</div>
        <div editable-area  [content]="main" [parentTemplateId]="metadata['mgnl:template']"></div>
    </main>

    <div class="Extras" >
        <div class="hint">[Extras Area]</div>
        <div editable-area  [content]="extras" [parentTemplateId]="metadata['mgnl:template']"></div>
        <button routerLink="/contact">Contact</button>
    </div>

</div>
import { Component, Input } from '@angular/core';

@Component({
  templateUrl: './basic.component.html',
  styleUrls: ['./basic.component.scss']
})
export class BasicComponent {
  @Input() title: any;

  @Input() main: any;
  @Input() extras: any;
  // metadata
  @Input() metadata: any;
}

In Vue js we define the routes in main.js.

main.js:

import Vue from 'vue';
import VueRouter from 'vue-router';
import App from './App.vue';
import PageLoader from './helpers/PageLoader.vue';

Vue.config.productionTip = false;
Vue.use(VueRouter);

const router = new VueRouter({
  mode: 'history',
  base: '/magnoliaAuthor/vue-minimal',
  routes: [{ path: '*', component: PageLoader }],
});

new Vue({
  router,
  render: (h) => h(App),
}).$mount('#app');

The App.vue is loading the proper routes using the PageLoader Component defined in main.js using the standard router-view.

The main entry point App.vue is looking like this:

<template>
  <div id="app">
    <header>
      <Navigation />
    </header>
    <div class="container">
      <router-view :key="$route.fullPath"></router-view>
    </div>
    <footer>
      Integer posuere erat a ante venenatis dapibus posuere velit aliquet.
      <br />Copyright © 2020
    </footer>
  </div>
</template>

<script>
import Navigation from "./components/Navigation";

export default {
  name: "app",
  components: {
    Navigation
  }
};
</script>

<style>
@import "./App.css";
</style>

Component Components 🤔

We learned earlier that the Magnolia SPA editor framework is helping to map the content structure created in Magnolia to frontend components. Let’s have a look at the Headline Component as an example.

  • React

  • Angular

  • Vue

src/components/Headline.js

import React from 'react';

const Headline = props => <h2 className="Headline">{props.text}</h2>;

export default Headline;

You can see how the fields defined in the dialog is passed through to the component, directly as `props`!

src/app/components/headline.component.html
<h2>{{text}}</h2>
src/app/components/headline.component.ts
import { Component, Input } from '@angular/core';

@Component({
  templateUrl: './headline.component.html',
  styleUrls: ['./headline.component.scss'],
})
export class HeadlineComponent {
  @Input() text: any;
}

You can see how the fields defined in the dialog is passed directly through to the component!

<template>
  <h2 class="Headline">{{ text }}</h2>
</template>

<script>
export default {
  name: 'Headline',
  props: ['text'],
};
</script>

You can see how the fields defined in the dialog is passed directly through to the component!

Build a Component

In the ``Headless CMS'' tutorial we have created a headless app to show tour packages. Using the Visual SPA Editor and the basic Form-Centric approach is not mutually exclusive. On the contrary, both approaches complement each other.

What are we going to build?

We will build a Tour List Component. Our Marketers will be able to choose and add the component anywhere they want.

  • Create a new component using light modules.

  • Create a dialog for Marketers to add a headline.

Create Tour List Component

Let’s create a new Component in Magnolia CMS first.

  1. Go to:

    minimal-headless-spa-demos
    cd magnolia/light-modules/spa-lm/templates/components
    touch tourList.yaml
  2. Edit the component file tourList.yaml and paste in:

    title: Tour List
    dialog: spa-lm:components/tourList

Dialog

Next we will define a simple dialog for our Marketers.

cd ../../dialogs/components
touch tourList.yaml

Edit the dialog file tourList.yaml and paste in:

label: Tour List
form:
  properties:
    headline:
      label: Tour List Headline
      $type: textField
      i18n: true

Make the Component available

Next we want to define where the component can be used. We will add our tourList Component to the available components of our Basic Page

  • React

  • Angular

  • Vue

cd ../../../react-minimal-lm/templates/pages

Edit the file basic.yaml and add following text to the availableComponents from the main Area:

TourList:
  id: spa-lm:components/tourList

The full file will look like this:

title: "React: Basic"
baseUrl: http://localhost:3000
routeTemplate: '/{language}{{@path}}'
# templateScript: /react-minimal-lm/webresources/build/index.html
dialog: spa-lm:pages/basic

renderType: spa
class: info.magnolia.rendering.spa.renderer.SpaRenderableDefinition

areas:
  main:
    title: Main Area
    availableComponents:
      Headline:
        id: spa-lm:components/headline
      Image:
        id: spa-lm:components/image
      Paragraph:
        id: spa-lm:components/paragraph
      Expander:
        id: spa-lm:components/expander
      List:
        id: spa-lm:components/list
      TourList:
        id: spa-lm:components/tourList

  extras:
    title: Extras Area
    availableComponents:
      Headline:
        id: spa-lm:components/headline
      Paragraph:
        id: spa-lm:components/paragraph
      List:
        id: spa-lm:components/list
cd ../../../angular-minimal-lm/templates/pages

Edit the file basic.yaml and add following text to the availableComponents from the main Area:

TourList:
  id: spa-lm:components/tourList

The full file will look like this:

title: "Angular: Basic"
baseUrl: http://localhost:4200
routeTemplate: '/{language}{{@path}}'
# templateScript: /angular-minimal-lm/webresources/build/index.html
dialog: spa-lm:pages/basic

renderType: spa
class: info.magnolia.rendering.spa.renderer.SpaRenderableDefinition

areas:
  main:
    title: Main Area
    availableComponents:
      Headline:
        id: spa-lm:components/headline
      Image:
        id: spa-lm:components/image
      Paragraph:
        id: spa-lm:components/paragraph
      Expander:
        id: spa-lm:components/expander
      List:
        id: spa-lm:components/list
      TourList:
        id: spa-lm:components/tourList

  extras:
    title: Extras Area
    availableComponents:
      Headline:
        id: spa-lm:components/headline
      Paragraph:
        id: spa-lm:components/paragraph
      List:
        id: spa-lm:components/list
cd ../../../vue-minimal-lm/templates/pages

Edit the file basic.yaml and add following text to the availableComponents from the main Area:

TourList:
  id: spa-lm:components/tourList

The full file will look like this:

title: 'Vue: Basic'
baseUrl: http://localhost:3000
routeTemplate: '/{language}{{@path}}'
# templateScript: /vue-minimal-lm/webresources/dist/index.html
dialog: spa-lm:pages/basic

renderType: spa
class: info.magnolia.rendering.spa.renderer.SpaRenderableDefinition

areas:

  main:
    title: Main Area
    availableComponents:
      Headline:
        id: spa-lm:components/headline
      Image:
        id: spa-lm:components/image
      Paragraph:
        id: spa-lm:components/paragraph
      Expander:
        id: spa-lm:components/expander
      List:
        id: spa-lm:components/list
      TourList:
        id: spa-lm:components/tourList
  extras:
    title: Extras Area
    availableComponents:
      Headline:
        id: spa-lm:components/headline
      Paragraph:
        id: spa-lm:components/paragraph
      List:
        id: spa-lm:components/list

Now we can already select the component in the Page Editor.

Open the Pages App and add your component.

spa first component page editor

But of course before we can see anything displayed, we have to implement the frontend component.

The Frontend Component

Our new component is now provisioned in Magnolia, and an instance of it is saved to the content repository. First, we want the component to display the Header entered by the Marketer. Once this is running and we have seen how to add and edit the component in the SPA Editor, we will extend the component to read and display our Tour List data.

Now, let’s build out our component in React, Angular or Vue.

  • React

  • Angular

  • Vue

  1. Switch to our React SPA directory:

    cd ../../../../../spa/react-minimal
  2. Go to the components directory:

    cd src/components
  3. Create a new file for our component:

    touch TourList.js
  4. Edit the Component:

    import React from "react";
    
    export default ({ headline }) => ( (1)
      <div className="tourlist">
        <h1>{headline}</h1>
      </div>
    );
    1 We will print the headline surrounded by a div.
  5. Next, open the Magnolia Config file to add our component to the mapping.

    src/magnolia.config.js
  6. Import the new component:

    import TourList from "./components/TourList";
  7. Add to mapping:

    'spa-lm:components/tourList': TourList

The full file looks like this:

import Basic from "./pages/Basic";
import Contact from "./pages/Contact";
import Headline from "./components/Headline";
import Image from "./components/Image";
import Paragraph from "./components/Paragraph";
import Expander from "./components/Expander";
import List from "./components/List";
import Item from "./components/Item";
import TourList from "./components/TourList";

const config = {
  componentMappings: {
    "react-minimal-lm:pages/basic": Basic,
    "react-minimal-lm:pages/contact": Contact,

    "spa-lm:components/headline": Headline,
    "spa-lm:components/image": Image,
    "spa-lm:components/paragraph": Paragraph,
    "spa-lm:components/expander": Expander,
    "spa-lm:components/list": List,
    "spa-lm:components/listItem": Item,
    "spa-lm:components/tourList": TourList
  }
};

export default config;
Ensure that your SPA development server is running. If not, in the /spa/react-minimal directory run:
npm run start
  1. Switch to our Angular SPA directory:

    cd ../../../../../spa/angular-minimal
    ng generate component components/TourList
    output
    CREATE src/app/components/tour-list/tour-list.component.css (0 bytes)
    CREATE src/app/components/tour-list/tour-list.component.html (24 bytes)
    CREATE src/app/components/tour-list/tour-list.component.spec.ts (643 bytes)
    CREATE src/app/components/tour-list/tour-list.component.ts (286 bytes)
  2. Add the new created TourListComponent into your app.module.ts file. Add it as an import and to the declarations and entryComponents. (It might have been added by the ng command, but double-check entryComponents.)

    import { TourListComponent } from './components/tour-list/tour-list.component';
    ...
      declarations: [
    
        TourListComponent,
    ...
      ],
      entryComponents: [
    ...
        TourListComponent,
    ...
  3. Open the Magnolia Config file to add our component to the mapping.

    src/magnolia.config.js
  4. Import the new component:

    import { TourListComponent } from "./app/components/tour-list/tour-list.component";
  5. Add to mapping:

    'spa-lm:components/tourList': TourListComponent
    Full file example
    import { BasicComponent } from "./app/pages/basic/basic.component";
    import { ContactComponent } from "./app/pages/contact/contact.component";
    import { HeadlineComponent } from "./app/components/headline/headline.component";
    import { ListItemComponent } from "./app/components/list-item/list-item.component";
    import { ListComponent } from "./app/components/list/list.component";
    import { ParagraphComponent } from "./app/components/paragraph/paragraph.component";
    import { ImageComponent } from "./app/components/image/image.component";
    import { ExpanderComponent } from "./app/components/expander/expander.component";
    import { TourListComponent } from "./app/components/tour-list/tour-list.component";
    
    export const config = {
      componentMapping: {
        "angular-minimal-lm:pages/basic": BasicComponent,
        "angular-minimal-lm:pages/contact": ContactComponent,
    
        "spa-lm:components/headline": HeadlineComponent,
        "spa-lm:components/list": ListComponent,
        "spa-lm:components/listItem": ListItemComponent,
        "spa-lm:components/paragraph": ParagraphComponent,
        "spa-lm:components/image": ImageComponent,
        "spa-lm:components/expander": ExpanderComponent,
        "spa-lm:components/tourList": TourListComponent
      }
    };
  6. Change the tour-list.component.ts file with following content:

    import { Component, Input } from "@angular/core";
    
    @Component({
      templateUrl: "./tour-list.component.html",
      styleUrls: ["./tour-list.component.css"]
    })
    export class TourListComponent {
      @Input() headline: any;
    }
    Please ensure that the styleUrls path correctly points to the style file, it might have a .css or it might have a .scss extension. (It depends on your angular CLI setup. Tricky!)
  7. Edit the TourList component template.

    src/app/components/tour-list/tour-list.component.html
    <div className="tourlist">
      <h1>{{ headline }}</h1>
    </div>
  8. Ensure that your SPA development server is running. If not, in the /spa/angular-minimal directory run:

    ng serve
  1. Switch to our Vue SPA directory:

    cd ../../../../../spa/vue-minimal
  2. Go to the components directory:

    cd src/components
  3. Create a new file for our component:

    touch TourList.vue
  4. Edit the Component:

    <template>
      <div class="tourlist"> (1)
        <h1>{{headline}}</h1>
      </div>
    </template>
    
    <script>
    export default {
      name: "TourList",
      props: ["headline"]
    };
    </script>
    1 We will just print the headline surrounded by a div.
  5. Next, open the Magnolia Config file to add our component to the mapping.

    src/magnolia.config.js
  6. Import the new component:

    import TourList from "./components/TourList";
  7. Add to mapping:

    'spa-lm:components/tourList': TourList
    Full file example
    import Basic from './pages/Basic';
    import Contact from './pages/Contact';
    import Image from './components/Image';
    import Headline from './components/Headline';
    import Paragraph from './components/Paragraph';
    import List from './components/List';
    import Item from './components/Item';
    import Expander from './components/Expander';
    import TourList from "./components/TourList";
    
    const config = {
      componentMappings: {
        // Pages
        'vue-minimal-lm:pages/basic': Basic,
        'vue-minimal-lm:pages/contact': Contact,
    
        // Components
        'spa-lm:components/headline': Headline,
        'spa-lm:components/image': Image,
        'spa-lm:components/paragraph': Paragraph,
        'spa-lm:components/list': List,
        'spa-lm:components/listItem': Item,
        'spa-lm:components/expander': Expander,
        'spa-lm:components/tourList': TourList
      },
    };
    
    export default config;
  8. Ensure that your SPA development server is running. If not, in the /spa/vue-minimal directory run:

    npm run start

Try your Component

Now that you implemented your component, open up the Page Editor again and view your page.

Your component is displayed.

Nice work!

You’ve just gone through the complete cycle of building a component (with handles and knobs on it) that a marketer can place in a visual SPA Editor.

Next, keep going with your new component. Bring in the tour listing logic you implemented in the `Hello Magnolia - Headless' section into your new component.

Displaying List of Tours

Our Component is up and running. Next we want to:

  • Upload some Demo Content

  • Define the REST API endpoint

  • Extend our Frontend Component to display the list of tours

Add Tours Content Type

In the folder spa-lm switch to contentTypes directory:

cd ./contentTypes

Create a file named `tours.yaml`and copy following content into it:

datasource:
  workspace: tours
  autoCreate: true

model:
  properties:
    name:
      label: Name
      required: true
      i18n: true

    description:
      label: Description
      i18n: true

    isFeatured:
      type: Boolean #Types 'Decimal', 'Long' and 'Double' are also available.
      label: Feature this item

    image:
      type: asset
      label: Image

    tourTypes:
      label: Tour Types

    location:
      label: Start City
      i18n: true

    date:
      label: Date
      type: Date

    duration:
      type: Long
      label: Tour Duration
      options:
        "2":
          value: 2
          label: 2 days
        "7":
          value: 7
          label: 7 days
        "14":
          value: 14
          label: 14 days
        "21":
          value: 21
          label: 21 days

    tourOperator:
      label: Tour Operator
      i18n: true

    body:
      type: richText
      label: Body
      i18n: true

Create a Magnolia App

Change to the spa-lm/apps directory.

cd ../apps

Create a file named tours.yaml with following content:

!content-type:tours
name: tours
label: Tours

# Optionally override any of the app configuration supplied by the content type.
subApps:
  detail:
    label: Detail Tour
    form:
      properties:
        isFeatured:
          buttonLabel: "Featured"
        tourTypes:
          $type: jcrMultiValueField
          type: String
          field:
            $type: linkField
            chooser:
              workbenchChooser:
                appName: categories
To see your new Tours app, log out and log back in, and press the grid icon.

Install content

We have prepared Demo Content to start with. To install the Demo Content follow these steps:

  • Open the Tours app.

  • Click Import action (You might need to scroll down in the action bar.).

  • Select the file ./magnolia/_dev/content-to-import/tours.magnolia-travels.xml.

import tours content

Add Tours REST API Endpoint

In the folder spa-lm switch to restEndpoints/delivery directory:

cd ./restEndpoints/delivery

Create a file named `tours.yaml`and copy following content into it:

class: info.magnolia.rest.delivery.jcr.v2.JcrDeliveryEndpointDefinition
workspace: tours
depth: 10
bypassWorkspaceAcls: true
includeSystemProperties: true
nodeTypes:
  - mgnl:content

references:
  - name: assetReference
    propertyName: image
    referenceResolver:
      class: info.magnolia.rest.reference.dam.AssetReferenceResolverDefinition
      assetRenditions:
        - 960x720
        - 480x360

This creates our new REST endpoint. Give it a try:

Finish the Frontend Component

Finally, we can extend our TourList Component to fetch and display the imported data.

  • Angular

  • Vue

Add some more styling

In /spa/react-minimal/src/components create a file TourList.css in the same directory as TourList.js and copy in this stylesheet:

.tour-list .tour-list-cards {
  display: flex;
  flex-wrap: wrap;
  justify-content: center;
}

.tour-list .tour-list-cards .card {
  max-width: 150px;
  margin-right: 15px;
  margin-bottom: 15px;
  -webkit-box-shadow: 10px 10px 28px -4px rgba(0, 0, 0, 0.53);
  -moz-box-shadow: 10px 10px 28px -4px rgba(0, 0, 0, 0.53);
  box-shadow: 10px 10px 28px -4px rgba(0, 0, 0, 0.53);
  transition: transform 0.4s ease-in-out;
  cursor: pointer;
}

.tour-list .tour-list-cards .card .card-img-top {
  width: 150px;
}

.tour-list .tour-list-cards .card .card-body {
  padding: 5px;
}

.tour-list .tour-list-cards .card .card-body .card-text {
  margin: 5px;
  opacity: 0.8;
  font-size: 10px;
  font-weight: 200;
  transition: opacity 0.8s ease-in;
}

.tour-list .tour-list-cards .card .card-body .card-title {
  margin: 0;
  font-weight: 200;
}

.tour-list .tour-list-cards .card:hover {
  transform: scale3d(1.5, 1.5, 1.5);
  transform-origin: center;
  background-color: #ffffff;
}

.tour-list .tour-list-cards .card:hover .card-body .card-text {
  opacity: 1;
}

.tour-list .tour-list-cards .card:hover .card-body .card-title {
  color: #00b39b;
}

Open your TourList.js file, and replace the code with this:

import React, { useState, useEffect } from "react";
import "./TourList.css";

const API_ENDPOINT =
  "http://localhost:8080/magnoliaAuthor/.rest/delivery/tours";
const IMAGE_BASE = "http://localhost:8080";

export default ({ headline }) => {
  const [tours, setTours] = useState([]);

  useEffect(() => {
    async function fetchTourList() {
      let response = await fetch(API_ENDPOINT);
      let data = await response.json();
      setTours(data.results);
    }
    fetchTourList();
  }, []);

  return (
    <div className="tour-list">
      <h1>{headline}</h1>
      {tours.length > 0 ? (
        <div className="tour-list-cards">
          {tours.map(tour => (
            <div class="card">
              <img
                src={IMAGE_BASE + tour.image.renditions["480x360"].link}
                class="card-img-top"
                alt="..."
              />
              <div class="card-body">
                <h5 class="card-title">{tour.name}</h5>
                <p class="card-text">{tour.description}</p>
              </div>
            </div>
          ))}
        </div>
      ) : (
        <h2>No Tours found</h2>
      )}
    </div>
  );
};

Add some more styling

Open the tour-list.component.css file in your previously created component directory /spa/angular-minimal/src/app/components/tour-list and copy in the following stylesheet:

It might be tour-list.component.scss depending on the configuration of your Angular CLI.
.tour-list .tour-list-cards {
  display: flex;
  flex-wrap: wrap;
  justify-content: center;
}

.tour-list .tour-list-cards .card {
  max-width: 150px;
  margin-right: 15px;
  margin-bottom: 15px;
  -webkit-box-shadow: 10px 10px 28px -4px rgba(0, 0, 0, 0.53);
  -moz-box-shadow: 10px 10px 28px -4px rgba(0, 0, 0, 0.53);
  box-shadow: 10px 10px 28px -4px rgba(0, 0, 0, 0.53);
  transition: transform 0.4s ease-in-out;
  cursor: pointer;
}

.tour-list .tour-list-cards .card .card-img-top {
  width: 150px;
}

.tour-list .tour-list-cards .card .card-body {
  padding: 5px;
}

.tour-list .tour-list-cards .card .card-body .card-text {
  margin: 5px;
  opacity: 0.8;
  font-size: 10px;
  font-weight: 200;
  transition: opacity 0.8s ease-in;
}

.tour-list .tour-list-cards .card .card-body .card-title {
  margin: 0;
  font-weight: 200;
}

.tour-list .tour-list-cards .card:hover {
  transform: scale3d(1.5, 1.5, 1.5);
  transform-origin: center;
  background-color: #ffffff;
}

.tour-list .tour-list-cards .card:hover .card-body .card-text {
  opacity: 1;
}

.tour-list .tour-list-cards .card:hover .card-body .card-title {
  color: #00b39b;
}

Open your tour-list.component.ts file and replace it with this code:

import { Component, Input } from '@angular/core';
import { HttpClient } from '@angular/common/http';

const API_ENDPOINT =
  "http://localhost:8080/magnoliaAuthor/.rest/delivery/tours";
const IMAGE_BASE = "http://localhost:8080";


@Component({
  templateUrl: './tour-list.component.html',
  styleUrls: ['./tour-list.component.scss'] (1)
})
export class TourListComponent {
  @Input() headline: any;
  @Input() tours: any;

  constructor(private http: HttpClient) {
    this.http = http;
  }

  ngOnInit() {
    this.http.get(API_ENDPOINT).subscribe((data: any) => {
      this.tours = data.results.map(item => ({ ...item, image: IMAGE_BASE + item.image.renditions[role=zoom,"480x360"].link }));
    })

  }
}
1 You might have to change the styleUrls to tour-list.component.scss depending on the name of your actual file.

Edit the TourList component template `tour-list.component.html`and replace it with this content:

<div class="tour-list">
    <h1>{{ headline }}</h1>
    <div class="tour-list-cards">

        <div class="card" *ngFor="let tour of tours">
        <img
        [src]="tour.image"
            class="card-img-top"
            alt="..."
        />
        <div class="card-body">
            <h5 class="card-title">{{tour.name}}</h5>
            <p class="card-text">{{tour.description}}</p>
        </div>
        </div>

      </div>
</div>

Add some more styling

In /spa/vue-minimal/src/components open your TourList.vue file and add at the end of it the stylesheet:

<style scoped>
.tour-list .tour-list-cards {
  display: flex;
  flex-wrap: wrap;
  justify-content: center;
}

.tour-list .tour-list-cards .card {
  max-width: 150px;
  margin-right: 15px;
  margin-bottom: 15px;
  -webkit-box-shadow: 10px 10px 28px -4px rgba(0, 0, 0, 0.53);
  -moz-box-shadow: 10px 10px 28px -4px rgba(0, 0, 0, 0.53);
  box-shadow: 10px 10px 28px -4px rgba(0, 0, 0, 0.53);
  transition: transform 0.4s ease-in-out;
  cursor: pointer;
}

.tour-list .tour-list-cards .card .card-img-top {
  width: 150px;
}

.tour-list .tour-list-cards .card .card-body {
  padding: 5px;
}

.tour-list .tour-list-cards .card .card-body .card-text {
  margin: 5px;
  opacity: 0.8;
  font-size: 10px;
  font-weight: 200;
  transition: opacity 0.8s ease-in;
}

.tour-list .tour-list-cards .card .card-body .card-title {
  margin: 0;
  font-weight: 200;
}

.tour-list .tour-list-cards .card:hover {
  transform: scale3d(1.5, 1.5, 1.5);
  transform-origin: center;
  background-color: #ffffff;
}

.tour-list .tour-list-cards .card:hover .card-body .card-text {
  opacity: 1;
}

.tour-list .tour-list-cards .card:hover .card-body .card-title {
  color: #00b39b;
}
</style>

Next replace script with this:

<script>
const API_ENDPOINT =
  "http://localhost:8080/magnoliaAuthor/.rest/delivery/tours";

export default {
  name: "TourList",
  props: ["headline"],
  data() {
    return {
      tours: [],
      imageBase: "http://localhost:8080"
    };
  },
  created() {
    this.fetchTours();
  },
  methods: {
    async fetchTours() {
      let response = await fetch(API_ENDPOINT);
      let data = await response.json();
      this.tours = data.results;
    }
  }
};
</script>

And extend the template to display the tours by replacing template with following code:

<template>
  <div class="tour-list">
    <h1>{{headline}}</h1>
    <div v-if="tours.length > 0" class="tour-list-cards">
      <div class="card" v-for="tour in tours" v-bind:key="tour.path">
        <img
          v-bind:src="imageBase + tour.image.renditions['480x360'].link"
          class="card-img-top"
          alt="..."
        />
        <div class="card-body">
          <h5 class="card-title">{{tour.name}}</h5>
          <p class="card-text">{{tour.description}}</p>
        </div>
      </div>
    </div>
    <h2 v-else>No Tours found</h2>
  </div>
</template>

You have upgraded your SPA component. Now open up the Page Editor again and view your page.

You will see the new tour list.

Next Steps

Well done!

You’ve fully upgraded a simple headless SPA into one marketers can fully manage, including placing a sophisticated listing component.

Next, take a well earned break.

Then, after this nitty-gritty hands-on practical work, learn more about the Visual SPA Editor.

Or get big-picture theoretical with the topics in the `Concepts' section.
