IntelliJ IDEA 13.1.0 Web Help

Some features described here are available in Ultimate edition only.

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_CoffeeScript icon.

To run, debug, and test your code you will need it translated into JavaScript which requires a transpiler and Node.js. For more details on CoffeeScript transpilation, see Transpiling CoffeeScript to JavaScript.

In this section:

Preparing for CoffeeScript development
  1. Make sure the CoffeeScript and Node.js plugins are installed and enabled.

    These plugins are not bundled with IntelliJ IDEA, but they are available from the JetBrains plugin repository. Once enabled, the plugins are available at the IDE level, that is, you can use them in all your IntelliJ IDEA projects. See Enabling and Disabling Plugins for details.

  2. Download and install the Node.js framework.
  3. Configure the Node.js interpreter in IntelliJ IDEA:
    1. Choose File | Settings and in the Settings dialog box that opens, click Node.js and NPM.
    2. On the Node.js page that opens, specify the location of the desired Node.js interpreter.

    • Common refactoring procedures, such as extract method , inline, rename/move, etc.
    • CoffeeScript-specific refactoring procedures, such as change signature, extract parameter, extract variable. These types of refactoring are identical with JavaScript, for more details, see the section JavaScript-Specific Refactorings
  • Code generation
    • Generating code stubs based on file templates during file creation.
    • Ability to create line and block comments ( or or or or or , or , or or or or or / or or or or or or , or or , , , , or , , or ).

  • Executing CoffeeScript files involves:
    • Ability to preview results of CoffeeScript files compilation to JavaScript.
    • Ability to launch CoffeeScript files from the context menu.
    • Run/debug configuration for NodeJS includes the ability to use CoffeeScript plugin.
