Installation

Overview

In this section, we are going to make our local system ready to install and develop the demo projects.

Preparation

If Node.js, NPM, and Java (JRE SE, On Windows, the JDK is required) are already installed on your computer, you can jump directly to installing Magnolia CLI.

You also need git installed for this tutorial.

Get Java

Magnolia needs at least a Java Runtime Environment (JRE) to run. Check if there’s a version of Java already installed on your computer by opening the terminal or command prompt and typing java -version. If the system reports a version number, Java is installed on your computer.

See Certified stack to confirm that the version installed is supported.
  • Windows

  • Mac

  • Linux

On Windows, you need a Java SE Development Kit (JDK). The Java Runtime Environment (JRE) is not enough because the Tomcat application server does not recognize it.

  • JRE is for users who run Java programs on their computers.

  • JDK is for developers who write Java-based applications.

Download and install JDK. By default, JDK is installed at C:\Program Files\Java\jdk-<version>\.

Instructions

Check for JAVA_HOME

  1. Open the command prompt.

  2. Type set and press ENTER.

  3. Find JAVA_HOME in the command output and verify that the path points to your JDK installation directory, for example, C:\Program Files\Java\jdk-<version>>.xx.

  4. If JAVA_HOME is missing or it points to the wrong directory, see Set JAVA_HOME.

Set JAVA_HOME

  1. Open the Command Prompt as an administrator.

  2. Set the path for JAVA_HOME.

    setx /m JAVA_HOME "path\to\Java\jdk" (1)
    1 Where path\to\Java\jdk is where your Java Development Kit is saved.

The set command creates the JAVA_HOME environment variable and sets its value to the JDK directory. The command is executed when Magnolia starts.

For Mac, you need to download or update to Java 11 or higher. After reviewing and agreeing to the terms of the license agreement, download the file, then double-click it to launch the installation wizard and follow the installation instructions.

The installation directory varies from one Linux system to another. On Debian-based distributions, JREs or JDKs are usually installed in /usr/lib/jvm/.

Get nodejs and npm

Magnolia CLI runs on Node.js and npm, the Node.js package manager. Use the following two shell commands to check that you have both of them installed:

node -v
npm -v

If you do not have Node.js installed, go to Node.js, download and install the latest LTS version.

For installation instructions of npm, see https://docs.npmjs.com/downloading-and-installing-node-js-and-npm.

Get Magnolia CLI

Run the following command in a shell to install Magnolia CLI:

  • Mac or Linux

  • Windows

sudo npm install @magnolia/cli -g
npm install @magnolia/cli -g (1)
1 Depending on your permissions and the location where you have installed Node.js, you may have to execute the command above with root permissions. Without installation permissions you will notice messages such as npm ERR! in the shell.

If the installation is successful, you see the following or a similar output in the shell:

/usr/bin/mgnl -> /usr/lib/node_modules/@magnolia/cli/bin/mgnl.js

> spawn-sync@1.0.15 postinstall /usr/lib/node_modules/@magnolia/cli/node_modules/spawn-sync
> node postinstall

+ @magnolia/cli@2.2.0
added 209 packages in 11.40

Once you have installed Magnolia CLI, test the installation by running the following command in the shell:

mgnl help
Usage: mgnl <command> [options]

A tool to setup and facilitate light development with Magnolia CMS

Options:
  -v, --version output the version number
  -h, --help output usage information

Commands:
  jumpstart download and setup a Magnolia CMS instance for development.
  start start up a Magnolia CMS instance. To stop it, enter CTRL-C
  add-availability add component availability.
  build scan a node_modules folder for npm packages with the keyword "magnolia-light-module" (in package.json) and extract them to a directory of choice.
  create-app create an app.
  create-block create a block.
  create-component create a component and optionally add availability for it.
  create-content-type create a content type.
  create-light-module create a light module.
  create-page create a page template.
  create-virtual-uri create a virtual uri mapping.
  customize-local-config extract "mgnl-cli-prototypes" folder and "mgnl-cli.json" file to customize CLI configuration.
  install install a light module from npm to the local Magnolia instance.
  search search for a light module on npm.
  tab-completion install tab autocomplete feature for Bash, zsh or PowerShell
  version display mgnl and node.js versions
  help [cmd] display help for [cmd]
