IntelliJ IDEA provides CoffeeScript support. IntelliJ IDEA recognizes
*.coffee files, and allows you to edit them providing full range of coding assistance without any additional steps from your side. CoffeeScript files are marked with icon.
Preparing for CoffeeScript development
- Make sure the CoffeeScript and Node.js plugins are installed and enabled. The plugins are not bundled with IntelliJ IDEA, but they can be installed from the JetBrains plugin repository as described in Installing, Updating and Uninstalling Repository Plugins and Enabling and Disabling Plugins. Once enabled, the plugins are available at the IDE level, that is, you can use them in all your IntelliJ IDEA projects.
- Download and install the Node.js runtime environment.
- Configure the Node.js interpreter in IntelliJ IDEA:
- Open the Settings / Preferences Dialog by choosing for Windows and Linux or for macOS, and click Node.js and NPM under Languages & Frameworks.
- On the Node.js and NPM page that opens, specify the location of the desired Node.js interpreter.
See Configuring Node.js Interpreters for details.
