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.If you're using TypeScript 2.0 to 3.6, 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.Īugust 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 Currently versions 3.7 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 example:įor an npm package "foo", typings for it will be at you can't find your package, look for it on TypeSearch. What are declaration files and how do I get them?
