TypeScript Support

RubyMine supports developing and running TypeScript source code. RubyMine recognizes *.ts files, and allows you to edit them providing full range of coding assistance without any additional steps from your side. TypeScript files are marked with the icon.

To run, debug, and test your code you will need it translated into JavaScript which requires a transpiler.

In this section:

• Transpiling TypeScript to JavaScript
• Running TypeScript
• Debugging TypeScript
• Using TSLint Code Quality Tool

Preparing for TypeScript Development

1. Make sure the JavaScript Support plugin is enabled. The plugin is bundled with RubyMine and activated by default. If the plugin is not activated, enable it on the Plugins page of the Settings / Preferences Dialog as described in Enabling and Disabling Plugins.
2. Make sure the Node.js plugin is installed and enabled. The plugin is not bundled with RubyMine, but it can be installed from the JetBrains plugin repository as described in Installing, Updating and Uninstalling Repository Plugins and Enabling and Disabling Plugins.

Coding Assistance

TypeScript support includes:

• Code completion for keywords, labels, variables, parameters, and functions.
• Error and syntax highlighting.
• Code formatting and folding.
• Numerous code inspections and quick-fixes.
• Refactoring:
  • Common refactoring procedures, such as extract method , inline, rename/move, etc.
  • TypeScript-specific refactoring procedures, such as change signature, extract parameter, extract variable.

  See JavaScript-Specific Refactorings for details.

• Code generation
  • Generating code stubs based on file templates during file creation.
  • Ability to create line and block comments (Ctrl+Slash/Ctrl+Shift+Slash).
  • Downloading stubs for TypeScript definition files and configuring them as a RubyMine JavaScript library (see Configuring JavaScript Libraries).
  • Generating import statements for modules, classes, and any other symbol that can be exported and called as a type, see Creating Imports, section Importing TypeScript Symbols.

    You can also configure the type of quotes to be used in import statements by choosing Double quotes or Single quotes from the String literal type drop-down list on the Code Style. TypeScript page of the Settings dialog box.

  • Configuring automatic insertion or skipping the public access modifier in generated code.
• Navigation and search through the source code:
  • Navigating with Structure View.
  • Navigate | Declaration (Ctrl+B).
  • Navigate | Implementation (Ctrl+Alt+B) from overridden method / subclassed class.
• Transpiling to JavaScript for further running, debugging, and testing, see Running TypeScript and Debugging TypeScript.
