NodeJS 过滤，分页和排序

// GET /tasks?completed=true
// GET /tasks?limit=2&skip=2
// GET /tasks?sortBy=createdAt:desc
router.get("/tasks", auth, async (req, res) => {
  const match = {};
  const sort = {};
  if (req.query.completed) {
    match.completed = req.query.completed === "true";
  }
  if (req.query.sortBy) {
    const parts = req.query.sortBy.split(":");
    sort[parts[0]] = parts[1] === 'desc' ? -1 : 1;
  }
  try {
    await req.user.populate({
      path: "tasks",
      match,
      options: {
        limit: parseInt(req.query.limit || 0), 
        skip: parseInt(req.query.skip || 0), 
        sort
      },
    });

    res.send(req.user.tasks);
  } catch (e) {
    res.send(e);
  }
});
