Integrate TypeScript Into a Remix Loader Function

We can take advantage of TypeScript by setting our loader function to the LoaderFunction type from @remix-run/node

Then we can ensure that our loader is returning the type that we want by creating a custom type called LoaderData with a property of posts.

We’ll also do a cool trick where we get the awaited return type of our getPosts async function. This is done like this posts: Awaited<ReturnType<typeof getPosts>>
