JavaScript and TypeScript Nightly

VS Code extension that enables the nightly build of TypeScript (typescript@next) as VS Code's built-in TypeScript version used to power JavaScript and TypeScript IntelliSense.

⚠️ You do not need this extension to work with JavaScript and TypeScript in VS Code.

This extension is intended for advanced users who want to test out the latest TypeScript features before they are released. VS Code includes built-in JavaScript and TypeScript support that uses the latest stable TypeScript release. You do not need this extension — or any other extensions — for editing JavaScript and TypeScript in VS Code.

Please only install this extension if you understand what it does and are ok trading a potentially less stable experience for testing out new TypeScript language and tooling features early.

Enabling

This extension replaces VS Code's built-in TypeScript version with typescript@next. It does not affect workspace versions of TypeScript, or custom user typescript.tsdk settings.

To make sure you are using typescript@next:

1. Open a JavaScript or TypeScript file in VS Code.
2. In the VS Code command palette, run the TypeScript: Select TypeScript version command.
3. Make sure you have Use VS Code's version selected

Note that this extension also includes the latest JavaScript and TypeScript grammar.
