如果你正在使用mongoose作为一个restful api的源，请看看 ' retify -mongoose'和它的查询。它内置了这个功能。

集合上的任何查询都提供了在这里有用的标头

test-01:~$ curl -s -D - localhost:3330/data?sort=-created -o /dev/null
HTTP/1.1 200 OK
link: </data?sort=-created&p=0>; rel="first", </data?sort=-created&p=1>; rel="next", </data?sort=-created&p=134715>; rel="last"
.....
Response-Time: 37

所以基本上你得到了一个通用服务器，它对集合的查询具有相对线性的加载时间。这是非常棒的，如果你想要进行自己的实现，可以参考一下。

app.get("/:page",(req,res)=>{
        post.find({}).then((data)=>{
            let per_page = 5;
            let num_page = Number(req.params.page);
            let max_pages = Math.ceil(data.length/per_page);
            if(num_page == 0 || num_page > max_pages){
                res.render('404');
            }else{
                let starting = per_page*(num_page-1)
                let ending = per_page+starting
                res.render('posts', {posts:data.slice(starting,ending), pages: max_pages, current_page: num_page});
            }
        });
});

最简单的分页插件。

https://www.npmjs.com/package/mongoose-paginate-v2

添加插件到一个模式，然后使用模型paginate方法:

var mongoose         = require('mongoose');
var mongoosePaginate = require('mongoose-paginate-v2');

var mySchema = new mongoose.Schema({ 
    /* your schema definition */ 
});

mySchema.plugin(mongoosePaginate);

var myModel = mongoose.model('SampleModel',  mySchema); 

myModel.paginate().then({}) // Usage

您可以使用skip()和limit()，但效率非常低。更好的解决方案是对索引字段加上limit()进行排序。 我们在Wunderflats发布了一个小库:https://github.com/wunderflats/goosepage 它用了第一种方法。

有一些很好的答案给出了使用skip()和limit()的解决方案，但是，在某些情况下，我们还需要文档计数来生成分页。以下是我们在项目中所做的:

const PaginatePlugin = (schema, options) => {
  options = options || {}
  schema.query.paginate = async function(params) {
    const pagination = {
      limit: options.limit || 10,
      page: 1,
      count: 0
    }
    pagination.limit = parseInt(params.limit) || pagination.limit
    const page = parseInt(params.page)
    pagination.page = page > 0 ? page : pagination.page
    const offset = (pagination.page - 1) * pagination.limit

    const [data, count] = await Promise.all([
      this.limit(pagination.limit).skip(offset),
      this.model.countDocuments(this.getQuery())
    ]);
    pagination.count = count;
    return { data, pagination }
  }
}

mySchema.plugin(PaginatePlugin, { limit: DEFAULT_LIMIT })

// using async/await
const { data, pagination } = await MyModel.find(...)
  .populate(...)
  .sort(...)
  .paginate({ page: 1, limit: 10 })

// or using Promise
MyModel.find(...).paginate(req.query)
  .then(({ data, pagination }) => {

  })
  .catch(err => {

  })

let page,limit,skip,lastPage, query;
 page = req.params.page *1 || 1;  //This is the page,fetch from the server
 limit = req.params.limit * 1 || 1; //  This is the limit ,it also fetch from the server
 skip = (page - 1) * limit;   // Number of skip document
 lastPage = page * limit;   //last index 
 counts = await userModel.countDocuments() //Number of document in the collection

query = query.skip(skip).limit(limit) //current page

const paginate = {}

//For previous page
if(skip > 0) {
   paginate.prev = {
       page: page - 1,
       limit: limit
} 
//For next page
 if(lastPage < counts) {
  paginate.next = {
     page: page + 1,
     limit: limit
}
results = await query //Here is the final results of the query.
