const ITEMS_PER_PAGE = 2;

最简单和更快速的方法是，用objectId进行分页 例子;

初始加载条件

condition = {limit:12, type:""};

从响应数据中获取第一个和最后一个ObjectId

下一页条件

condition = {limit:12, type:"next", firstId:"57762a4c875adce3c38c662d", lastId:"57762a4c875adce3c38c6615"};

下一页条件

condition = {limit:12, type:"next", firstId:"57762a4c875adce3c38c6645", lastId:"57762a4c875adce3c38c6675"};

在猫鼬

var condition = {};
    var sort = { _id: 1 };
    if (req.body.type == "next") {
        condition._id = { $gt: req.body.lastId };
    } else if (req.body.type == "prev") {
        sort = { _id: -1 };
        condition._id = { $lt: req.body.firstId };
    }

var query = Model.find(condition, {}, { sort: sort }).limit(req.body.limit);

query.exec(function(err, properties) {
        return res.json({ "result": result);
});

您可以像这样编写查询。

mySchema.find().skip((page-1)*per_page).limit(per_page).exec(function(err, articles) {
        if (err) {
            return res.status(400).send({
                message: err
            });
        } else {
            res.json(articles);
        }
    });

Page:来自客户端作为请求参数的页码。 Per_page:每页显示的结果数目

如果你正在使用MEAN堆栈，下面的博客文章提供了很多信息，在前端使用angular-UI引导和在后端使用猫鼬跳过和限制方法创建分页。

参见:https://techpituwa.wordpress.com/2015/06/06/mean-js-pagination-with-angular-ui-bootstrap/

你可以像这样串起来:

var query = Model.find().sort('mykey', 1).skip(2).limit(5)

使用exec执行查询

query.exec(callback);

这是一个示例函数，用于获得具有分页和限制选项的技能模型的结果

 export function get_skills(req, res){
     console.log('get_skills');
     var page = req.body.page; // 1 or 2
     var size = req.body.size; // 5 or 10 per page
     var query = {};
     if(page < 0 || page === 0)
     {
        result = {'status': 401,'message':'invalid page number,should start with 1'};
        return res.json(result);
     }
     query.skip = size * (page - 1)
     query.limit = size
     Skills.count({},function(err1,tot_count){ //to get the total count of skills
      if(err1)
      {
         res.json({
            status: 401,
            message:'something went wrong!',
            err: err,
         })
      }
      else 
      {
         Skills.find({},{},query).sort({'name':1}).exec(function(err,skill_doc){
             if(!err)
             {
                 res.json({
                     status: 200,
                     message:'Skills list',
                     data: data,
                     tot_count: tot_count,
                 })
             }
             else
             {
                 res.json({
                      status: 401,
                      message: 'something went wrong',
                      err: err
                 })
             }
        }) //Skills.find end
    }
 });//Skills.count end

}

使用ts-mongoose-pagination

    const trainers = await Trainer.paginate(
        { user: req.userId },
        {
            perPage: 3,
            page: 1,
            select: '-password, -createdAt -updatedAt -__v',
            sort: { createdAt: -1 },
        }
    )

    return res.status(200).json(trainers)
