NodeJS

A number of development tools require the installation and use of NodeJS, which is a JavaScript runtime environment available freely for most operating systems.

Moodle currently requires version 16.14 of NodeJS, which is otherwise known as lts/gallium.

We highly recommend using NVM to install NodeJS rather than installing it directly.

NVM

NVM is the Node Version Manager. Its purpose is to simplify the installation, and use of multiple versions of NodeJS.

Moodle includes a .nvmrc which nvm can use to select the correct version of NodeJS.

To use the correct version of NodeJS for the current version of Moodle, you can use the nvm install and nvm use commands:

$ nvm install
Found '/Users/nicols/Sites/public_html/sm/.nvmrc' with version <lts/gallium>
v16.14.0 is already installed.
Now using node v16.14.0 (npm v8.3.1)

Grunt

As part of it’s build stack, Moodle uses the Grunt task runner.

Grunt is composed of a set of tasks, defined within the Moodle code repository in the Gruntfile.js file, and a grunt CLI tool which must be installed separately.

To install the grunt CLI tool you can install it globally using npm:

$ npm install -g grunt-cli
$ grunt stylelint

Alternatively you can use the npx command to install it on demand:

$ npx grunt stylelint
