Confused about the return type of this function

So i have a function which fetches the user. My goal is to return user if exists else return null. However in order to achieve this i need to manually check the length of the response and if its zero i return null. Overall my code looks so much duplicated and verbose. I tried using this but this doesnt shows null as return type

You can try this:

async function getUser(name: string) {
  const results = await db.select().from(users).where(eq(users.name, name));
  return results.at(0) || null;
}

async function getUser(name: string) {
  const results = await db.select().from(users).where(eq(users.name, name));
  return results.at(0) || null;
}

Your initial code is not wrong; however, from the type system’s point of view, ⁠data can’t be undefined/null (that is wrong, it can).
