Nust Module for Nuxt

Nust is a nuxt module that allows NestJS like backend structure in nuxt, Standardizing your backend with CRUD structure, powering nuxt backend with features like:

• 🎮  Controllers
• 🖌️  Decorators
• 🛎️  Injectable providers/services
• 🪄️  Parameter extraction
• ✅️  Body/DTO Validation (using class-validator)
• 🔄️  Transformers (using class-transformer)
• 🔒️  Guards
• 📖️  OpenAPI documentation support, Nestjs like Api documentation decorators for better Swagger and Scalar support

Usage

1. Install the module to your Nuxt application:

npm i nuxt-nust

2. Add nuxt-nust to list of modules in your nuxt.config.ts file, along with nust configuration:

// nuxt.config.ts
export default defineNuxtConfig({
  modules: ['nuxt-nust'],
  nust: {
    controllersFile: 'server/nust/index.ts', // Path to controllers export file in your project relative to root folder
    debug: false, // Enable to show the routes added by your controllers in the logs
  }
})

3. Create a file in your project to export all controllers that sits under the path specified in the previous step, for example: server/nust/index.ts

// server/nust/index.ts
import { type NustControllers } from '#nust'

export default {
  // Here you'll be adding your controller classes
  // Example:
  // post: PostController
} satisfies NustControllers

4. Update the tsconfig.json files by adding the following lines:

{
  "extends": "../.nuxt/tsconfig.server.json",
  "compilerOptions": {
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "strictPropertyInitialization": false
  }
}

5. That's it! You can now use Nust Module in your Nuxt app ✨

Example of adding a controller, lets call this one CatController

1.Create a controller file under the nust directory, server/nust/cat/Cat.controller.ts

import { Controller, type H3Event } from '#nust'

@Controller('cat')
export class CatController {

  @Get('')
  findAll(event: H3Event) {
    return `this action returns all cats`
  }
  
}

2. Add controller to server/nust/index.ts file

// server/nust/index.ts
import {type NustControllers} from '#nust'
import { CatController } from "./cat/Cat.controller";

export default {
  cat: CatController
} satisfies NustControllers

3. Restart nuxt service
4. Now the endpoint /api/cat is available

Concept

Turn your server structure from this:

From this:

server/
├── api/
│   ├── cat/
│   │   ├── index.get.ts   //Find all
│   │   ├── index.post.ts  //Create
│   │   ├── [id].get.ts    //Find one
│   │   ├── [id].patch.ts  //Update
│   │   └── [id].delete.ts //delete
│   └── dog/
│       ├── index.get.ts   //Find all
│       ├── index.post.ts  //Create
│       ├── [id].get.ts    //Find one
│       ├── [id].patch.ts  //Update
│       └── [id].delete.ts //delete
└── utils/
    ├── catUtilss.ts
    └── dogUtils.ts

To this: (Just and example, structure can be however you like)

server/
├── nust/
│   ├── cat/
│   │   ├── dto/               // For example, you can add your CRUD dto's here
│   │   │   ├── CreateCat.dto.ts
│   │   │   └── UpdateCat.dto.ts
│   │   ├── entity/            // For example, you can add your resource relevent types here
│   │   ├── cat.controller.ts  // Has all the CRUD methods
│   │   └── cat.service.ts     // cat service provider, can be used to hold all logic, allowing it to be injected to any controller and reuse the logic
│   └── dog/
│   │   ├── dog.controller.ts  // Has all the CRUD methods
│   │   └── dog.service.ts     // dog service provider
└── index.ts                   // controllersFile, a file that exports an object of all controllers

If you've worked with other backend focused frameworks you'd find this structure familiar, where the logic for a CRUD resource all sits under one folder/module, helps keep the backend code organised and its logic reusable.

Resource controllers?

Your event handler changes from this:

//index.get.ts
export default defineEventHandler((event)=>{
  //...
  return //
})
//index.post.ts
export default defineEventHandler((event)=>{
  //...
  return //
})
//[id].get.ts
export default defineEventHandler((event)=>{
  //...
  return //
})
//[id].post.ts
export default defineEventHandler((event)=>{
  //...
  return //
})
//[id].delete.ts
export default defineEventHandler((event)=>{
  //...
  return //
})

To this:

import {Controller, Get, Post, Delete, Body, Param} from '#nust'

@Controller('cat') // Prefix can be defind here or you can just add it to each method
export class CatController {
  // Get all
  @Get('')
  findAll() {
    //...
  }

  // POST Create
  @Post('')
  create(event: H3Event, @Body(CreateCatDto) dto: CreateCatDto) {
    //...
  }

  // Get one
  @Get(':id')
  findOne(event: H3Event, @Param('id') id: string): CatEntity {
    //..
  }

  @Patch(':id')
  update(
    event: H3Event,
    @Param('id') id: string,
    @Body(UpdateCatDto) dto: UpdateCatDto,
  ) {
    //...
  }

  @Delete(':id')
  delete(event: H3Event, @Param('id') id: string) {
    //...
  }
  
  @Any('get-random-cat')
  otherNoneStandardCRUDmethod(event: H3Event) {
    //...
  }
}
