yupify - be fast, be type-safe

In fact, it's just a plugin for fastify that combinig validation schema declaration and typing for any request. No more, no less

Before

fastify.post<{ Querystring: { hello: string } }>(
  "/",
  { schema: { querystring: { hello: string } } },
  ({ query: { hello } }) => {
    return hello;
  }
);

After

yupify.post(
  "/",
  { [Yupify.Query]: yup.object({ hello: yup.string() }) },
  ({ query: { hello } }) => {
    return hello;
  }
);

When to use it

• You want pretty-damn easy solution to add schema validation to your fastify app
• You don't want to add messy generics to your codebase

When NOT to use it

• You need to have maximum control over the server (#todo)
