Part I - Installing and setting up the CLI and Magnolia

In the first part of this tutorial, you install the CLI and use it to set up Magnolia. You also create a prototype variant to later create a light module.

Get node.js

Magnolia CLI is an npm package providing a command line interface (CLI) tool to set up and facilitate light development with Magnolia. The Magnolia CLI tool runs on Node.js. If you do not have Node.js installed, go to Node.js and download and install the latest LTS version.

To check the version of your node installation, run the following command in a shell:

node -v

Unresolved include directive in modules/ROOT/pages/Magnolia-CLI-walkthrough/Part-I---Installing-and-setting-up-the-CLI-and-Magnolia.adoc - include::product-docs:ROOT:partial$i/_Get-Magnolia-CLI.adoc[]

Create your prototype

When you run create commands from the CLI, the new files are created based on prototype files. So for example, if you want to create a new page template then the basis for the template is specified by the prototype. Essentially, the prototype is the copy-base for new templates.

Global vs local

Prototypes can be global or local.

Global: The global configuration is created during the installation of the Magnolia CLI package. It will be used if no local configuration is found in the current directory or in its parent folders.
Local: The local configuration is created with the customize-local-config command. This creates files in the directory where you execute the command. After creation, you can edit the config to suit your needs.

For more information, see Magnolia CLI prototypes.

Prototype variants

Different prototype variants are available depending on what you are creating.

When executing the create-page and create-component commands you can choose one of the prototype variants provided out-of-the-box.

If you don’t specify a prototype using the -P option, then the _default is used.

Instead of using one of the prototypes provided, we will create our own variants. The easiest way of doing this is to copy and paste one of the existing prototype variants.

Create the local prototype configuration files

Create the local prototype configuration files by running the following CLI command in a shell:

mgnl customize-local-config

This command extracts the following items to your current folder:

mgnl‑cli‑prototypes/

A folder which contains the prototypes for template and dialog definitions and the README file.

mgnl‑cli.json

The configuration file defining the folders of the light module skeleton and some other things.

The prototype files are located in the mgnl-cli-prototypes folder you just extracted to your dev directory.

Create your prototype variants

Now you create prototype variants for the create-page and create-component commands based on the _default prototype you just extracted.

If you don’t want to create your prototype variant and edit the files, replace your dev/mgnl-cli-prototypes folder with the folder in this zip: mgnl-cli-prototypes.zip

To create a variant, copy and paste the existing default prototype:

For pages, in dev/mgnl-cli-prototypes/page, copy the _default folder and paste it at the same level. Rename your copy to my-page-prototype.
For components, in dev/mgnl-cli-prototypes/component, copy the _default folder and paste it at the same level. Rename your copy to my-component-prototype.

│ ├── _default
│ ├── empty

│ └── with-js-model
└── virtual-uri

Edit your variant files

Now you will edit your prototype files in your variant so that:

You add a CSS file to your page variant to generate a CSS and link it to pages you create later.
The create-page command creates a page template with just a title.
The create-component command creates a component with just a title and a description.

Add a CSS file

In the mgnl-cli-prototypes/page/my-page-prototype/ folder, create the following folders and file /webresources/css/name.css

mkdir -p webresources/css; touch $_/__name__.css

Open name.css file and add the following content:

h1 {
    font-family: Helvetica; color: #2A3D00;
}
body {
    background-color: #F5F8EA;
}

Edit the my-page-prototype variant

In the mgnl-cli-prototypes/page/my-page-prototype/dialogs/pages folder, open name.yaml and replace the definition with the following reduced version that corresponds to a simple title field being required when creating a page:

dev/mgnl-cli-prototypes/page/my-page-prototype/dialogs/pages/name.yaml

form:
  label: Page properties
  tabs:
    - name: tabMain
      label: __name__
      fields:
        - name: title
          class: info.magnolia.ui.form.field.definition.TextFieldDefinition
          i18n: true
          label: title
actions:
  commit:
    class: info.magnolia.ui.admincentral.dialog.action.SaveDialogActionDefinition
  cancel:
    class: info.magnolia.ui.admincentral.dialog.action.CancelDialogActionDefinition

In the mgnl-cli-prototypes/page/my-page-prototype/templates/pages folder, open name.ftl and replace the script with the following reduced version:

dev/mgnl-cli-prototypes/page/my-page-prototype/templates/pages/name.ftl

<!DOCTYPE html>
<html xml:lang="${cmsfn.language()}" lang="${cmsfn.language()}">
  <head>
   <link rel="stylesheet" type="text/css" href="${ctx.contextPath}/.resources/__lightDevModuleFolder__/webresources/css/__name__.css" media="all" />
    [@cms.page /]
    <title>${content.windowTitle!content.title!}</title>
  </head>
  <body>
    <div class="container ">
      <h1>${content.windowTitle!content.title!}</h1>
    </div>
  </body>
</html>

Note that in line 4 you add a link to the CSS that uses variables (lightDevModuleFolder and name.css) to generate part of the path to the light module folder and the name of the CSS file.

Edit the my-component-prototype variant

Next, in the mgnl-cli-prototypes/component/my-component-prototype/dialogs/components folder, open name.yaml and replace the definition with the following reduced version that corresponds to a component with a title field and a description:

dev/mgnl-cli-prototypes/component/component/my-component-prototype/dialogs/component/name.yaml

form:
  label: __name__
  tabs:
    - name: tabMain
      label: Main
      fields:
        - name: title
          class: info.magnolia.ui.form.field.definition.TextFieldDefinition
          label: Title
        - name: desc
          class: info.magnolia.ui.form.field.definition.RichTextFieldDefinition
          label: Description
actions:
  commit:
    class: info.magnolia.ui.admincentral.dialog.action.SaveDialogActionDefinition
  cancel:
    class: info.magnolia.ui.admincentral.dialog.action.CancelDialogActionDefinition

In the mgnl-cli-prototypes/component/my-component-prototype/templates/components folder, open name.ftl and replace the script with the following reduced version:

dev/mgnl-cli-prototypes/component/component/my-component-prototype/templates/component/name.ftl

<div class="__name__">
  [#if content.title?has_content]
    <h2>${content.title!}</h2>
  [/#if]
  [#if content.desc?has_content]
    ${cmsfn.decode(content).desc!}
  [/#if]
</div>

Start Magnolia with CLI

Go to the parent directory of the apache-tomcat directory and execute the Magnolia CLI start command:

mgnl start

When starting for the first time, Magnolia runs a web update and automatically installs all its modules.

Login

Go to http://localhost:8080/magnoliaAuthor and sign in as:

Username: superuser
Password: superuser

Magnolia is ready to use and gives you a list of suggestions to get started.

Logging into the Author instance

Go to http://localhost:8080/magnoliaAuthor and log in to the Author instance with:

Username: superuser
Password: superuser

When you log in, the first page you see is a list of suggestions generated by the Find Bar.

To see the list of the app tiles, click the App Launcher icon to the right of the Find Bar at the top.

The App Launcher is a key navigation page in Magnolia.

When you log in, the first page you see is the App Launcher, in which you can see groups of apps:

Congratulations. Magnolia is now installed and running.
