Crudify: Automate Your Mongoose CRUD Operations in NestJS

Are you tired of writing repetitive CRUD logic for your Mongoose models? Meet Crudify, a NestJS library designed to simplify your development workflow by automatically generating RESTful CRUD endpoints. With just a few lines of code, you can set up a fully functional API, complete with Swagger documentation and built-in logging.

📚 What is Crudify?

Crudify is a powerful tool for NestJS developers who work with Mongoose. It reduces boilerplate code by automating the creation of CRUD (Create, Read, Update, Delete) endpoints for your models. But that’s not all! It also provides automatic Swagger documentation and integrates a logger to handle uncaught errors, making your API more maintainable and developer-friendly.

With Crudify, you can:

• 🚀 Automatically generate CRUD endpoints for your Mongoose models.
• 📖 Get fully functional Swagger UI without any additional setup.
• 🛠️ Customize endpoints to fit your specific needs.
• 🧰 Simplify debugging with integrated logging.

🛠️ Quick Setup

1. Install Dependencies

npm install ncrudify

2. Define Your Model

import { Prop, Schema, SchemaFactory } from '@nestjs/mongoose';
import { Document } from 'mongoose';

@Schema()
export class User extends Document {
  @Prop({ required: true }) name: string;
  @Prop({ required: true, unique: true }) email: string;
  @Prop() age: number;
}

export const UserSchema = SchemaFactory.createForClass(User);

3. Create a Service

import { Injectable } from '@nestjs/common';
import { Model } from 'mongoose';
import { InjectModel } from '@nestjs/mongoose';
import { CrudifyService } from 'ncrudify';

@Injectable()
export class UserService extends CrudifyService<User> {
  constructor(@InjectModel(User.name) userModel: Model<User>) {
    super(userModel);
  }
}

4. Build a Controller

import { Controller } from '@nestjs/common';
import { UserService } from './user.service';
import { Crudify, CrudifyController } from 'ncrudify';

@Crudify({ model: { type: User } })
@Controller('users')
export class UserController extends CrudifyController<User> {
  constructor(public service: UserService) {
    super(service);
  }
}

🌐 Swagger Integration

Crudify makes it effortless to set up Swagger documentation for your API. Swagger automatically documents all your CRUD endpoints, making it easier to test and share your API with your team or external users.

Once set up, you can access the Swagger UI at http://localhost:3000/api, where you’ll find a user-friendly interface to interact with your API.

1. Import CrudifySwaggerModule in AppModule:

import { Module } from '@nestjs/common';
import { MongooseModule } from '@nestjs/mongoose';
import { CrudifySwaggerModule } from 'ncrudify';

@Module({
  imports: [
    MongooseModule.forRoot(process.env.MONGODB_URI),
    CrudifySwaggerModule,
  ],
})
export class AppModule {}

2. Setup Swagger in main.ts:

import { NestFactory } from '@nestjs/core';
import { CrudifySwaggerModule } from 'ncrudify';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  CrudifySwaggerModule.setupSwagger(app);
  await app.listen(3000);
}
bootstrap();

🧰 Integrated Logging

Crudify includes a logger to capture and manage uncaught errors, making your debugging process more efficient. The logger is based on Errsole, a tool designed to help developers track runtime errors and improve error handling.

How to Enable the Logger

1. Import CrudifyLoggerModule in AppModule:

import { CrudifyLoggerModule } from 'ncrudify';

@Module({
  imports: [CrudifyLoggerModule],
})
export class AppModule {}

2. Access the Logger UI

By default, the Crudify Logger listens on http://localhost:3001. You can access this interface to see all uncaught errors, including stack traces and request details, which makes identifying and fixing issues faster.

Customize the Logger

You can adjust the logger’s configuration by providing custom options, such as log levels or output destinations, to match your project’s needs.

🔎 Advanced Query Filters

Crudify supports powerful query filters using a simple format:

field=[$operator]:value

Examples

• age=[$gt]:30 - Find users older than 30.
• name=[$eq]:John - Find users named John.

Supported Operators

• $eq: Equal to
• $ne: Not equal to
• $gt: Greater than
• $lt: Less than
• $gte: Greater than or equal to
• $lte: Less than or equal to
• $cont: Contains (for strings)
• $excl: Does not contain (for strings)
• $in: In a set of values
• $notin: Not in a set of values
• $isnull: Is null
• $notnull: Is not null
• $between: Between two values
