 Redwood does not use the TypeScript compiler; instead, we use babel, which strips out the types before transpiling them.

+#### Getting types for `jest` in test files
+
+If you're adding tests, you'll want to include the types for `jest` in your `tsconfig`.

++"types": ["jest"]
+```
+
+Currently, these are added to `node_modules` by `@redwoodjs/core` and the above approach should just work. If this is not the case, you can `yarn add -D @types/jest` in the `web` folder and they will resolve.
