Request-Parser

This package allows for automatically parsing query parameters and map them to a prisma compatible format to be automatically appended to FindMany calls.

Usage

First, you need to add the decorator to a method in your controller.

@Controller()
export class UserController {
  constructor(private readonly userService: UserService) {}

  @Get()
  getAll(@RequestParser() requestParams: ParsedQueryModel) {
    console.log(requestParams);
    return this.userService.getAll(requestParams);
  }
}

Then call the route as follows:

example.com/api/users?sort=-id,name&limit=20&page=5

will return 20 entries from the 5th page (i.e., entry 81 - 100). Entries are ordered by id (descending) and name (ascending).

Query Parameter Schema

sort	order by attribute. Comma separated list of attributes. - in front of a attribute (i.e., -id) means order by attribute descending.	id

page	describe the page that should be retrieved (use in combination with limit)	1
