Streamlining Filtering in NestJS

If you’ve been working with NestJS for a while, you know the drill. You set up your services, build some endpoints, and — oh no — here comes the query filtering. Time to write yet another block of repetitive code just to let users filter data by name, date, status, or whatever else they need.

Been there? Same. That’s exactly why nestjs-filter, a package designed to make query filtering in NestJS so easy.

A Tale of Too Many Filters!

Every time you found yourself writing the same filtering logic over and over again. It was like that one chore you keep putting off but can’t avoid. 😅

This worked, but it wasn’t fun, scalable, or particularly clever.🤷

What Exactly Is nestjs-filter? 🤔

Great question! nestjs-filter is like the personal assistant you wish you had for query filtering. Instead of manually writing all that boilerplate, you just plug it in, and it takes care of the rest. Here’s a sneak peek:

import { Inject, Injectable } from '@nestjs/common';
import { Product } from '../model/product';
import { GenericRepository, QueryParamsDto } from 'nestjs-filter';
@Injectable()
export class ProductService {
 constructor(
 @Inject('GENERIC_REPOSITORY')
 private readonly productRepository: GenericRepository<Product>
 ) {}

async findAll(queryParams: QueryParamsDto): Promise<Product[]> {
 return await this.productRepository.findWithFilters(queryParams).get();
 }
}

Boom. Done. No more boilerplate. 🚀
