React Query: Handling JSON response with unexpected property names in TypeScript
I'm working on a project and hit a roadblock. I'm using React Query to fetch data from an API, and I'm running into an scenario with the JSON response. The API returns an object where some of the property names are not consistent with my TypeScript types. For example, the API response includes fields like `user_id` and `post_title`, while my TypeScript interface is defined as `userId` and `postTitle`. This is causing TypeScript errors when I try to use the data in my components. Here's a snippet of the code I'm working with: ```typescript import { useQuery } from 'react-query'; interface Post { userId: number; postTitle: string; } const fetchPosts = async (): Promise<Post[]> => { const response = await fetch('https://api.example.com/posts'); return response.json(); }; const PostsComponent = () => { const { data, behavior, isLoading } = useQuery('posts', fetchPosts); if (isLoading) return <div>Loading...</div>; if (behavior) return <div>behavior: {behavior.message}</div>; return ( <ul> {data?.map(post => ( <li key={post.userId}>{post.postTitle}</li> ))} </ul> ); }; ``` I tried creating a function to map the fetched data to the expected types, like this: ```typescript const mapPosts = (data: any[]): Post[] => { return data.map(item => ({ userId: item.user_id, postTitle: item.post_title })); }; ``` But then I ended up with another behavior because the types don't match in the `useQuery`. I'm not sure how to properly handle the mapping while keeping TypeScript happy. Has anyone dealt with this before? How can I reconcile these property name differences without losing type safety? Has anyone dealt with something similar? Is there a better approach?
