This is a plugin for [graphql-compose](https://github.com/graphql-compose/graphql-compose) family, which adds to the ObjectTypeComposer `pagination` resolver.

Live demo: [https://graphql-compose.herokuapp.com/](https://graphql-compose.herokuapp.com/)

[CHANGELOG](https://github.com/graphql-compose/graphql-compose-pagination/blob/master/CHANGELOG.md)

## Installation

```bash
npm install graphql graphql-compose graphql-compose-pagination --save
```

Modules `graphql` and `graphql-compose` are in `peerDependencies`, so should be installed explicitly in your app. They should not installed as sub-modules, cause internally checks the classes instances.

## Example

```js
import { preparePaginationResolver } from 'graphql-compose-pagination';
import { UserTC, findManyResolver, countResolver } from './user';

const paginationResolver = preparePaginationResolver(UserTC, {
  findManyResolver,
  countResolver,
  name: 'pagination', // Default
  perPage: 20, // Default
});
```

Implementation of `findManyResolver` and `countResolver` can be found in [this file](./src/__mocks__/User.ts).
