nestjs-prisma-crud

CRUD utility for simple REST use cases. Builds on top of NestJS and Prisma. Inspired by @nestjsx/crud.

Installation

npm i nestjs-prisma-crud --save
npm i nestjs-prisma-crud-schematics --save-dev

Why

When building REST API's there is common functionality that we would prefer not to implement again and again. This package offers minimal and opinionated out of the box solutions for some of those (see features below).

✔ Features

An overview of the provided functionality:

  1. Advanced client side joining, sorting, filtering and pagination via query parameters
    • Any valid prisma .where can be sent by the frontend.
    • Server side validation to safeguard against arbitrarily deep .join or .where clauses by clients.
    • Support for including only specific properties in the response.
  2. Access control
    • @AccessPolicy decorator with default utilities that support functionalities similar to RBAC/ABAC.
    • Custom policy support.
  3. Atomic operations
    • Supports POST/PATCH with nested objects.
    • Transaction support when extending controller functionality.
  4. Schematics
    • crud-resource: a modified NestJS resource schematic that scaffolds the entire CRUD module for you.
      One-line scaffolding with: nest g -c nestjs-prisma-crud-schematics crud-resource <YOUR-TABLE-NAME-HERE>
  5. Plug and play
    • Can be used alongside your other non nestjs-prisma-crud controllers.
    • You can still use PrismaCrudService and @AccessPolicy in your custom controllers if you want to retain some of nestjs-prisma-crud's functionalities.

Quickstart

Assumes both NestJS and Prisma2 are already setup. See Getting Started.

  1. Install nestjs-prisma-crud and nestjs-prisma-crud-schematics:

    npm i nestjs-prisma-crud
    npm i nestjs-prisma-crud-schematics --save-dev
    
  2. Generate the entire crud module with a single command (replace post with your model's name):

    nest g -c nestjs-prisma-crud-schematics crud-resource post
    
  3. Setup your service and controller

    // post.service.ts
    import { Injectable } from '@nestjs/common';
    import { PrismaCrudService } from 'nestjs-prisma-crud';
    
    @Injectable()
    export class PostService extends PrismaCrudService {
        constructor() {
            super({
                model: 'post',
                allowedJoins: ['comments.author'],
            });
        }
    }
    
    // post.controller.ts
    import { PostService } from './post.service';
    
    @Controller('post')
    export class PostController {
        constructor(private readonly postService: PostService) {}
    
        @Get()
        async findMany(@Query('crudQuery') crudQuery: string) {
            const matches = await this.postService.findMany(crudQuery);
            return matches;
        }
    }
