Update import paths when a file is moved or renamed (opens new window)

VS Code can now automatically update import paths when a JavaScript or TypeScript file is moved or renamed:

This feature requires TypeScript 2.9. By default, VS Code will prompt you if we can update paths. You can control the prompting behavior with the javascript.updateImportsOnFileMove.enabled and typescript.updateImportsOnFileMove.enabled settings.

Valid values are:

• "prompt" - The default. Asks if paths should be updated.
• "always" - Always automatically update paths.
• "never" - Do not update paths automatically and do not prompt.

To make sure all paths are updated as expected, make sure your project includes a jsconfig.json (opens new window) or tsconfig.json (opens new window).

Highlight unused variables and imports (opens new window)

Unused variables, parameters, and imports are now greyed out in JavaScript and TypeScript:

Use a Quick Fix to remove them and clean up your code automatically:

After cleanup:

This can be disabled by setting "javascript.showUnused": false and "typescript.showUnused": false.

Move to new file refactoring (opens new window)

A new Move to a new file refactoring for JavaScript and TypeScript lets you quickly move classes and functions to their own file:

Improved JS/TS auto suggest (opens new window)

IntelliSense is now shown automatically in a few more places. These include:

• After typing a < inside jsx code.
• After typing a / to close a jsx tag.
• After typing a ' or " for a string literal type in TypeScript.

Generate getter/setter refactoring (opens new window)

A new Generate 'get' and 'set' accessors refactoring lets you quickly encapsulate a field in JavaScript and TypeScript:

Before:

After:

Syntax aware folding enabled by default for JS/TS (opens new window)

Syntax aware folding is now enabled by default for JavaScript and TypeScript. A preview of this feature first shipped with VS Code 1.22 but there were a few bugs that we wanted to fix before turning it on for everyone.

The new syntax aware folding should match the old indentation based folding in most cases, however indentation based folding sometimes creates more folding ranges that you may be used to. To revert back to using the old indentation based folding, set:

"[javascript]": {
  "editor.foldingStrategy": "indentation"
},
"[javascriptreact]": {
  "editor.foldingStrategy": "indentation"
},
"[typescript]": {
  "editor.foldingStrategy": "indentation"
},
"[typescriptreact]": {
  "editor.foldingStrategy": "indentation"
}

Preferences for auto imports and generated code (opens new window)

You can now explicitly specify the quote and path styles that VS Code uses for auto imports and other generated JavaScript and TypeScript code.

The new javascript.preferences.quoteStyle and typescript.preferences.quoteStyle settings specify the type of quotes to use.

Valid values are:

• "single" quotes.
• "double" quotes.
• "auto" to infer quote type from existing imports.

The javascript.preferences.importModuleSpecifier and typescript.preferences.importModuleSpecifier settings specify the type of path to use for imports.

Valid values are:

• "relative" to the file location.
• "non-relative" based on the baseUrl configured in your jsconfig.json / tsconfig.json.
• "auto" to infer the shortest path type.

These new preferences require TypeScript 2.9+.

Import folding (opens new window)

Blocks of import statements are now foldable in JavaScript and TypeScript:

This feature requires TypeScript 2.9+. You must also have semantic folding enabled (it is enabled by default). Make sure you have "editor.foldingStrategy" set to "auto" and that you have not set "typescript.experimental.syntaxFolding": false
