在Meteor中按日期过滤Mongo文档

meteor add mongo

const filteredPosts = Posts.find({
  createdAt: {
    $gte: new Date('2022-01-01'), // 大于等于指定日期
    $lt: new Date('2022-02-01') // 小于指定日期
  }
}).fetch();

Template.myTemplate.onCreated(function() {
  this.filteredPosts = new ReactiveVar([]);

  this.autorun(() => {
    const posts = Posts.find({
      createdAt: {
        $gte: new Date('2022-01-01'),
        $lt: new Date('2022-02-01')
      }
    }).fetch();

    this.filteredPosts.set(posts);
  });
});

Template.myTemplate.helpers({
  posts() {
    return Template.instance().filteredPosts.get();
  }
});
