nestjs-methodset

MethodSet is an abstract controller that when extended will provide:

• All the required GET/DELETE/POST/UPDATE endpoints for the TypeORM repository.
• List endpoint contains: pagination, order, search, filter options.
• filter options contains: =, gt, gte, lt, lte

nestjs-methodSet is influenced by ViewSet in Django Rest Framework

Installation

npm i nestjs-methodset

in main.ts add following to the app:

import { ValidationPipe } from '@nestjs/common';
...
  app.useGlobalPipes(new ValidationPipe({ transform: true }));

Code

• Simply extends MethodSet in your controller and you done. Make sure to have the repository in your controller dependencies!

import { MethodSet } from 'nestjs-methodset';

@Controller({ path: 'article' })
export class ArticleController extends MethodSet<ArticleEntity> {
	constructor(
		@InjectRepository(ArticleEntity)
		protected readonly repository: Repository<ArticleEntity>
	) {
		super();
	}
}

• Now your API has the following implemented functions:
  • get: GET /article/<id>
  • list: GET /article
  • post: POST /article
  • update: UPDATE /article/<id>
  • delete: DELETE /article/<id>

the list endpoint contains different options as following:

• page & pageSize: ?&page=1&pageSize=3
• orderBy & sortOrder(default: DESC): ?orderBy=timestamp&sortOrder=ASC
• search : ?search=test
  • Must specify search fields in the controller, ie:

  searchFields: SearchFields<ArticleEntity> = ['body', 'title'];

• filter[]:
  • separate conditions by , ie: ?filter=price__lte=10,total=2,
  • Or can be written: ?filter[]=price__lte=10&filter[]=total=2

• <field>__gt=<value>, greater than, ie: filter=price__lte=10
