mongoose-simple-pagination v1.0.0

mongoose-simple-pagination

Mongoose simple pagination plugin written specially for typescript and async purposes.

Why?

I created this package because I met typing problems in alternative libraries such as mongoose-paginate-v2. This package is for people who looking for typescript solution with typings.

Installation

npm i mongoose-simple-pagination

Usage

Add plugin to a schema and then use model paginate method:

import { Document, model, Schema } from 'mongoose';

import { mongooseSimplePagination, PaginationModel } from 'mongoose-simple-pagination';

interface Product extends Document {
  // ...
}

const productSchema = new Schema<Product>(
  {
    // ...
  }
);

productSchema.plugin(mongoosePaginate);

export const ProductModel = model<Product, PaginationModel<Product>>(
  'Product',
  productSchema,
  'products'
);

(async () => {
  const pagination = await ProductModel.paginate();
  const products = pagination.documents; // Our products array.
  const hasNextPage = pagination.hasNextPage; // true.
})();
