@typescript/typescript6

This package provides a tsc6 command that runs TypeScript 6's tsc.

It also reexports the TypeScript 6 API, so you can import it in your code:

import ts6 from "@typescript/typescript6";

Side-by-side with TypeScript 7

TypeScript 7 does not yet ship a stable programmatic API. For tools that still need the TypeScript 6 JS API (for example typescript-eslint), install this package alongside TypeScript 7 via npm aliases. See Running Side-by-Side with TypeScript 6.0.

Recommended layout:

{
  "devDependencies": {
    "@typescript/native": "npm:typescript@^7.0.2",
    "typescript": "npm:@typescript/typescript6@^6.0.2"
  }
}

Package layout (@typescript/old)

This package depends on @typescript/old (npm:typescript@^6), which contains the real TypeScript 6 API implementation.

After install, node_modules/typescript (when aliased to this package) is a thin compatibility entrypoint. The large API bundle lives under:

node_modules/@typescript/old/lib/typescript.js

If you use path-based ignores or excludes aimed at node_modules/typescript/ (for example Jest transformIgnorePatterns, bundler excludes, or size checks), also cover node_modules/@typescript/. Otherwise tools may still process the ~8MB @typescript/old bundle.

Example (Jest):

transformIgnorePatterns: [
  "/node_modules/typescript/",
  "/node_modules/@typescript/",
]
