  • How to install Node.js.

Since Antora is built on Node.js, you’ll need Node.js (commands: node, npm, and npx) installed on your machine to install and run Antora.


You can use any active LTS or maintenance LTS version of Node.js with Antora, but we recommend using the most recent active LTS version so that you benefit from the latest performance and security enhancements. The Node.js release schedule shows the active Node.js LTS versions.

To see if you have Node.js installed, and which version, open a terminal and type:

$ node --version

You should see a version string, such as:


If the command fails with an error, it means you don’t have Node.js installed. The best way to install Node.js is to use nvm (Node Version Manager). Skip to Install nvm and Node.js to find instructions.

If the command returns a version that isn’t an active LTS version, upgrade to the latest Node.js LTS version using nvm (or your package manager).

If the command returns an active Node.js LTS version, make sure that version is set as your default version by typing the following command in your terminal:

$ nvm alias default 16

Now you’re ready to install Antora.

Install nvm and Node.js

We recommend using the Node Version Manager (nvm) to manage your Node.js installations, though this is not a requirement. Follow the nvm installation guide to set up nvm on your machine. Once you’ve successfully installed nvm, close your current terminal, open a new one, and return here.

If you get nvm: command not found after running the install script, then it did not complete successfully. Be sure to follow all prompts issued by the install script. Consult the troubleshooting section in the install guide if you run into problems.
Many CI environments use nvm to manage the version of Node.js used in the build job. By using nvm, you can align your setup with the environment used to generate and publish your production site.

Once you’ve installed nvm, open a new terminal and install the active Node.js LTS release.

$ nvm install --lts

The above command will install the active LTS release of Node.js and automatically set it as your default alias.

Now that you have Node.js set up, you can install Antora.

Upgrade Node.js using nvm

If you have nvm installed, but don’t have the latest LTS version installed, type the following command in your terminal:

$ nvm install --lts

To set the latest version of Node.js as the default for any new terminal, type:

$ nvm alias default 16

Now that you’re on the latest LTS version of Node.js, you can install Antora.
