In this section we will go through the prerequisites needed for Magnolia Headless Accelerator (HA).

To use Headless Accelerator you must install Node.js version 14 or higher, Java, Git, and Yarn on your device. If you have all of those already, go directly to the installation of Magnolia CLI.

1. Install Node.js#

To see if you already have Node.js installed and check the installed version, run the following commands:

node -v

If you don't have Node.js installed or it is not version 14 or higher, please follow these instructions.

curl -o- | bashexport NVM_DIR="$HOME/.nvm"[ -s "$NVM_DIR/" ] && \. "$NVM_DIR/"  # This loads nvm[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completionnvm install 14nvm alias default 14

Node Version Manager (NVM) allows you to install and switch between multiple versions of Node.js and npm on your system.

2. Install Java#

You need to have Java installed on your system to run Magnolia. Make sure to use the version of Java supported by Magnolia. Check the the Magnolia Certified Stack for up-to-date information.

As of February 2022 supported versions of Java are Java 16 (supported by Magnolia 6.2.9+), Java 11 and Java 8.

Run this command to see the Java version installed:

java -version

If you do not have this setup already, please do the following:

Go to, download according to your platform.


Make sure you're using ARM compatible JDK when using Macbook M1 with the new Apple CPU.

3. Setup Git#

You can check if Git is installed on your device by running git --version. To configure your Git environment run:

git config --global "My Name"git config --global

If you don't have Git installed, you can find the installation bundles here:

4. Install Yarn#

If you haven't installed Yarn, run:

npm i -g yarn

5. Install Magnolia CLI#

The Headless Accelerator uses the Magnolia CLI to setup and facilitate light development with Magnolia. For more information visit Magnolia CLI documentation.

To install Magnolia CLI run this command:

npm i -g @magnolia/cli

You can check if Magnolia CLI is successfully installed by running command mgnl --version.

6. Install HA CLI#

To install Headless Accelerator CLI run:

npm install @magnolia/ha-cli -g

7. Install needed dependencies#

To install all needed dependencies, run ha command for the first time.

HA CLI asks for the Nexus credentials, setups the .npmrc file in the users home directory and installs all needed dependencies.

Once this is done, you can re-run your command and use the full HA functionality.

You will also have access to the @magnolia-dx and @magnolia-ea scope.

If you run HA in a CI Environment , you can copy your access token to MGNL_HA_AUTH_TOKEN environment variable. If the HA command finds this variable it will not prompt for username and password authentication.

8. (Optional) Install Web components#

You can use UXF Web components to speed up your development process.

npm install @magnolia-ea/uxf-core

NOTE: Make sure you run the ha command (see step 6).


You successfully installed all of the prerequisites.

Now you're ready to jumpstart your Headless project with Magnolia Headless Accelerator!
