A monorepo for formerly disparate DefinitelyTyped-related tools:

• definitions-parser: the part of microsoft/types-publisher that reads DefinitelyTyped repository data
• dtslint: microsoft/dtslint, make sure a package is correct for DT
• dtslint-runner: DefinitelyTyped/dtslint-runner, test all packages, or all changed packages, on DT with dtslint
• eslint-plugin: provides DT-specific lint rules
• dts-critic: DefinitelyTyped/dts-critic, issue errors when a types packages mismatches its original Javascript package.
• header-parser: microsoft/definitelytyped-header-parser, check and extract DT-related info from package.json
• publisher: the rest of microsoft/types-publisher
• retag: DefinitelyTyped/dt-retag, script to add ATA tags to @types packages. Run weekly.
• typescript-versions: the part of definitelytyped-header-parser that tracked which TypeScript versions are published to npm and supported on DefinitelyTyped
• utils: shared utilities, mostly extracted from microsoft/types-publisher

These tools are not intended for public consumption, so we may break the API whenever convenient for us.

This is a monorepo managed with pnpm workspaces and published with changesets. After cloning, run pnpm install to install dependencies for each package and link them to each other.

All packages use jest, with a single configuration set up to be run from the monorepo root. pnpm test is an alias for jest, so you can run tests with any of jest’s CLI options. For example, to run tests for a single package:

pnpm test packages/utils

types-publisher runs in GitHub Actions using all monorepo packages built from source on master.

The public packages are published to npm using changesets. When making changes to any publishable package, run pnpm changeset (ideally as part of the related feature PR) to mark the changed packages for eventual version bumping and release. When that PR is merged, another PR will be automatically opened (or updated) updating package versions and CHANGELOGs. What that PR is merged, a workflow will publish the changed packages to npm.
