Hosts TSConfigs to extend in a TypeScript app, tuned to a particular runtime environment

Centralized Recommendations for TSConfig bases

Hosts TSConfigs for you to extend in your apps, tuned to a particular runtime environment. Owned and improved by the community. Basically Definitely Typed for TSConfigs.

We target the latest stable version of TypeScript, note that because we want to be consistent with the versioning the target runtime we can't always do semver releases.

What about combined configs?

Because of previous limitations in the config extension system of TypeScript, this repo used to provide combined configs from a few common bases (like Node + ESM, Node + Strictest and so on).

This issue is now moot since TypeScript v5.0.0, which provides the ability to extend from multiple configs at once. For instance, if you want to start from a Node 18 + Strictest base config, you can install both @tsconfig/node18 and @tsconfig/strictest packages and extend those configs like so:

// tsconfig.json
{
  "extends": ["@tsconfig/strictest/tsconfig", "@tsconfig/node18/tsconfig"]
}

You can see the result of the combined configs via tsc --showConfig.

What about @tsconfig/esm?

We deprecated it in favour of setting module/moduleResolution to node/bundler.

Contributing

git clone https://github.com/tsconfig/bases.git tsconfig-bases
cd tsconfig-bases

Then edit the tsconfig.json files in bases/.

Every morning there is a GitHub Action which deploys any changed bases.

To generate the recommended TSConfig which is generated via tsc --init, run:

deno run --allow-read --allow-run --allow-env --allow-write --allow-net scripts/generate-recommend.ts

Developing

Create a set of npm packages via:

deno run --allow-read --allow-write --allow-net scripts/create-npm-packages.ts

You can inspect them in the packages/ folder, then they are deployed by passing in the paths to the base files via stdin:

deno run --allow-read --allow-run --allow-env --allow-net scripts/deploy-changed-npm-packages.ts

The rest of the files in this repo are for deploying, which uses Deno 1.0.

If you add a new json file, please run deno run --allow-read --allow-write scripts/update-markdown-readme.ts to update the README.
