      • [select] {Object | String} - Fields to return (by default returns all fields). Documentation
      • [sort] {Object | String} - Sort order. Documentation
      • [populate] {Array | Object | String} - Paths which should be populated with other documents. Documentation
      • [lean=false] {Boolean} - Should return plain javascript objects instead of Mongoose documents? Documentation
      • [leanWithId=true] {Boolean} - If lean and leanWithId are true, adds id field with string representation of _id to every document
      • [offset=0] {Number} - Use offset or page to set skip position
      • [page=1] {Number}
      • [limit=10] {Number}
      • [customLabels] {Object} - Developers can provide custom labels for the response data.
    • [callback(err, result)] - If specified the callback is called once pagination results are retrieved or when an error has occurred

    Return value

    Promise fulfilled with object having properties:

    • docs {Array} - Array of documents
    • totalDocs {Number} - Total number of documents in collection that match a query
    • limit {Number} - Limit that was used
    • hasPrevPage {Bool} - Availability of prev page.
    • hasNextPage {Bool} - Availability of next page.
    • page {Number} - Current page number
    • totalPages {Number} - Total number of pages.
    • offset {Number} - Only if specified or default page/offset values were used
    • prevPage {Number} - Previous page number if available or NULL
    • nextPage {Number} - Next page number if available or NULL

    Examples

    Return first 10 documents from 100

    Model.paginate({}, { page: 1, limit: 10 }, function(err, result) {
        // result.docs
        // result.totalDocs = 100
        // result.totalPages = 10
        // result.limit = 10
        // result.page = 1
        // result.nextPage = 2
        // result.prevPage = null
        // result.hasNextPage = true
        // result.hasPrevPage = false
    });

    Same query with custom labels

     
    var myCustomLabels = {
        docs: 'data',
        nextPage: 'next',
        prevPage: 'prev',
        totalPages: 'pageCount'
    };
     
    Model.paginate({}, { page: 1, limit: 10 }, function(err, result) {
        // result.docs <- here docs become data
        // result.totalDocs = 100
        // result.totalPages = 10
        // result.limit = 10
        // result.page = 1
        // result.next = 2 <- here nextPage becomes next
        // result.prev = null <- here prevPage becomes prev
        // result.hasNextPage = true
        // result.hasPrevPage = false
    });

    Or you can do the same with offset and limit:

    Model.paginate({}, { offset: 20, limit: 10 }, function(err, result) {
        // result.docs
        // result.totalPages
        // result.limit - 10
        // result.offset - 20
    });

    With promise:

    Model.paginate({}, { offset: 20, limit: 10 }).then(function(result) {
        // ...
    });

    More advanced example

    var query   = {};
    var options = {
        select:   'title date author',
        sort:     { date: -1 },
        populate: 'author',
        lean:     true,
        offset:   20, 
        limit:    10
    };
     
    Book.paginate(query, options).then(function(result) {
        // ...
    });

    Zero limit

    You can use limit=0 to get only metadata:

    Model.paginate({}, { offset: 100, limit: 0 }).then(function(result) {
        // result.docs - empty array
        // result.totalDocs
        // result.limit - 0
        // result.offset - 100
    });

    Set custom default options for all queries

    config.js:

    var mongoosePaginate = require('mongoose-custom-pagination');
     
    mongoosePaginate.paginate.options = { 
        lean:  true,
        limit: 20
    };

    controller.js:

    Model.paginate().then(function(result) {
        // result.docs - array of plain javascript objects
        // result.limit - 20
    });
