Fetch data with typed response from Zog schema

fetch.ts

// Create a schema for a post
const Post = z.object({
  slug: z.string(),
  content: z.string(),
});

// Create a schema for a post collection
const Posts = z.array(Post);

// Fetch a post by slug with the correct typed response
const fetchWithSchema = async <TSchema extends z.ZodType>(
  schema: TSchema,
  url: string
): Promise<z.infer<TSchema>> => {
  const result = await fetch(url).then((res) => res.json());
  return schema.parse(result);
};

const posts = fetchWithSchema(Posts, "/posts");
