TypeScript Internal Types

Expose TypeScript internal types by simply adding a development dependency.

Setup

1. Add aliased dependency to package.json (use the same version as your typescript version)

   {
     "devDependencies": {
       "typescript": "^3.9.6",
       // Note: The package is 'ts-expose-internals', but we are aliasing within the @types scope to make TS adopt it globally
       "@types/ts-expose-internals": "npm:ts-expose-internals@3.9.6"
     }
   }
   

2. Run npm install / yarn install

Usage

All internal types are now available within the primary typescript module

// This namespace is flagged @internal and is omitted from published types, but now we can access it!
import { JsDoc } from 'typescript'

How it works

This repository is deployed on a server which runs scripts/cron.sh every 12 hours.

The scripts compare our release tags with the TypeScript compiler's tags. If new versions are detected, it builds the compiler source, with internal types included, and publishes a new release with its types.

New types are added to the 'typescript' module via the Module Augmentation technique.

Notes

• We publish for TS releases only. If you'd like nightly builds, have a look at byots.
• If we don't have a package for the latest release, please allow 24hrs, then file an issue.
