IntelliJ IDEA 12.1.0 Web Help

11.0+
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.

  2. Download and install the Node.js framework.
  3. Configure the Node.js interpreter in IntelliJ IDEA:
    1. Click update_node_js.png on the main toolbar.
    2. On the Node.js page that opens, specify the location of the desired Node.js interpreter.

Coding assistance

CoffeeScript support includes:

  • Code completion for keywords, labels, variables, parameters and functions.
  • Error and syntax highlighting.
  • Code formatting and folding.
  • Refactoring:
    • 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 (Ctrl+Slash or Ctrl+NumPad /Ctrl+Slash or Ctrl+NumPad /Ctrl+Slash or Ctrl+NumPad /Ctrl+Slash or Ctrl+NumPad /Alt+SemicolonCtrl+Slash or Ctrl+NumPad /Ctrl+Slash, Ctrl+NumPad / or Ctrl+ColonCtrl+Slash, Ctrl+NumPad / or Ctrl+Shift+CCtrl+Slash or Ctrl+NumPad /Meta Slash or Meta NumPad /Meta Slash or Meta NumPad /Meta Slash or Meta NumPad //Ctrl+Shift+Slash or Ctrl+Shift+NumPad /Ctrl+Shift+Slash or Ctrl+Shift+NumPad /Ctrl+Shift+Slash or Ctrl+Shift+NumPad /Ctrl+Shift+Slash or Ctrl+Shift+NumPad /Ctrl+Shift+Slash or Ctrl+Shift+NumPad /Ctrl+Shift+Slash or Ctrl+Shift+NumPad /Ctrl+Shift+Slash, Ctrl+Shift+NumPad / or Ctrl+Shift+ColonCtrl+Shift+Slash or Ctrl+Shift+NumPad /Ctrl+Shift+SlashControl Shift Slash, Control Shift NumPad /, Meta Shift Slash or Meta Shift NumPad /Control Shift Slash, Control Shift NumPad /, Meta Shift Slash or Meta Shift NumPad /Control Shift Slash).
