![]() This code does not run, but it is type-checked. This contains sample code which tests the typings. This contains the typings for the package. Your package should have this structure: File (You can use npm info to check for the existence of the package.) If the package you are adding typings for is not on npm, make sure the name you choose for it does not conflict with the name of a package on npm. If you are adding typings for an npm package, create a directory with the same name. If you are the library author and your package is written in TypeScript, bundle the autogenerated declaration files in your package instead of publishing to Definitely Typed. If it doesn't, you can do so yourself in the comment associated with the PR. When you make a PR to edit an existing package, dt-bot should previous authors. If you make breaking changes, do not forget to update a major version. git sparse-checkout add types/ types/.-depth=1 will further improve clone speed by truncating commit history, but it may cause issues as summarized here.-filter=blob:none will exclude files, fetching them only as needed.-sparse initializes the sparse-checkout file so the working directory starts with only the files in the root of the repository.git clone -sparse -filter=blob:none -depth=1.More complicated procedures are available in older versions, but not covered by this guide. ⚠️ This requires minimum git version 2.27.0, which is likely newer than the default on most machines. This will reduce clone time and improve git performance. This will take some time to clone and may be unnecessarily unwieldy.įor a more manageable clone that includes only the type packages relevant to you, you can use git's sparse-checkout, -filter, and -depth features. You can clone the entire repository as per usual, but it's large and includes a massive directory of type packages. Partial clone You can clone the entire repository as per usual, but it's large and includes a massive directory of type packages. Here is a handy reference showing the life-cycle of a pull request to DT: You can read more about why and how here. We use a bot to let a large number of pull requests to DefinitelyTyped be handled entirely in a self-service manner. If using npm v7 you need to add the -legacy-peer-deps flag to the command. Once you've tested your package, you can share it on Definitely Typed.įirst, fork this repository, clone it, install node, and run npm install. Then follow the instructions to edit an existing package orĬreate a new package. Once you've tested your definitions with real code, make a PR Then build and run the code to make sure your type definition actually corresponds to what happens at runtime. You should now be able to import from "foo" in your code and it will route to the new type definition. How can I contribute?ĭefinitely Typed only works because of contributions by users like you! Testingīefore you share your improvement with the world, use the types yourself by creating a typename.d.ts file in your project and filling out its exports:Ĭreate types/foo/index.d.ts containing declarations for the module "foo". NuGet (use preferred alternatives, nuget DT type publishing has been turned off).Typings (use preferred alternatives, typings is deprecated).Manually download from the master branch of this repository and place them in your project.Here is the support packages have tags for versions of TypeScript that they explicitly support, so you can usually get older versions of packages that predate the 2-year window.įor example, if you run npm dist-tags you'll see that TypeScript 2.5 can use types for whereas TypeScript 2.6 and 2.7 can use types for Tag If you're using TypeScript 2.0 to 4.0, you can still try installing packages - the majority of packages don't use fancy new TypeScript features.īut there's no guarantee that they'll work. Currently versions 4.1 and above are tested. Support Windowĭefinitely Typed only tests packages on versions of TypeScript that are less than 2 years old. Or just look for any ".d.ts" files in the package and manually include them with a ///. This is usually provided in a "types" or "typings" field in the package.json, If you still can't find it, check if it bundles its own typings. For an npm package "foo", typings for it will be at you can't find your package, look for it on TypeSearch.
