Mongoose-paginate-ts NPM

mongoose-paginate-ts

Typescript pagination (with page or cursor) plugin for Mongoose

Installation

npm install mongoose-paginate-ts

Usage

Add plugin for a mongoose schema to inject a paginate method for pagination:

import { mongoosePagination, Pagination } from "mongoose-paginate-ts";
type User = mongoose.Document & {
  username: String,
  accounts: [mongoose.Types.ObjectId]
};
const userSchema = new Schema({
  username: String,
  accounts: [{ type: ObjectId, ref: "Account" }]
});
userSchema.plugin(mongoosePagination);
const User: Pagination<User> = mongoose.model<User, Pagination<User>>("User", userSchema);

//User.paginate()

Model.paginate(options, callback)

Parameters

[options] {Object}
- [query] {Object} - Query conditions. Documentation
- [select] {Object | String} - Fields to return (by default returns all fields). Documentation
- [sort] {Object | String} - Sort order. Documentation
- [populate] {Object | String} - Paths which should be populated with other documents. Documentation
- [page=1] {Number},
- [limit=10] {Number}, number of docs per page, default is 10
- [key=_id] {String}, cursor id pagination
- [startingAfter] {String}, A cursor for use in pagination. startingAfter is an object ID that defines your place in the list. For instance, if you make a list request and receive 100 objects, ending with obj_foo, your subsequent call can include startingAfter=obj_foo in order to fetch the next page of the list.
- [endingBefore] {String}, A cursor for use in pagination. endingBefore is an object ID that defines your place in the list. For instance, if you make a list request and receive 100 objects, starting with obj_bar, your subsequent call can include endingBefore=obj_bar in order to fetch the previous page of the list.
- [forceCountFunction=false] {Boolean} - Set this to true, if you need to support $geo queries.
- [lean=true] {Boolean} - Set this to false, if you need to disable the lean.
[callback(err, result)] - The callback is called once pagination results are retrieved or when an error has occurred

Result value

Promise fulfilled with an Pagination:

class PaginationModel {
  totalDocs: number | undefined;
  limit: number | undefined = 0;
  totalPages: number | undefined;
  page: number | undefined;
  pagingCounter: number | undefined;
  hasPrevPage: Boolean | undefined = false;
  hasNextPage: Boolean | undefined = false;
  prevPage: number | undefined;
  nextPage: number | undefined;
  hasMore: Boolean | undefined = false;
  docs: any[] = [];
}

Examples

Paginate with

User.paginate({}).then((error: Error, result: any) => {
  // ...
});

var results = await User.paginate({})

More advanced example

var options = {
  query: {},
  select: "title date author",
  sort: { date: -1 },
  populate: "account",
  limit: 5
};

User.paginate(options).then((error: Error, result: any) => {
