Elysia routing controllers

modular and concise template with decorators and services (inspired by nestjs)

• Elysia RESTAPI starter example
• Decorators for GET, POST, PUT and DELETE methods
• Familiar middleware like express (beforeHandle)
• by default, all requests are logged in the console ('GET -- /swagger -- 200 2023-10-02T00:48:20.857Z')
• swagger included, everytime you register new controller,view all routes (http://localhost:3500/swagger)

example controller

import { t } from 'Elysia';
import TasksService from './tasks.service';
import { AuthRoute } from '../../middlewares';
import { Delete, Get, Post, Put, BaseController } from '../../utils';

let TaskBody = t.Object({ title: t.String() });
let TaskResponse = t.Object({ id: t.Number(), title: t.String() });
let TaskListResponse = t.Array(TaskResponse);
let TaskParams = t.Object({ id: t.Numeric() });
let TaskQuery = t.Object({ limit: t.Optional(t.Numeric()) });

class TasksController extends BaseController {
  routes = []; // step 1

  constructor(public tasksService: TasksService) {
    super('/tasks'); // step 2
  }

  @Get('/', { query: TaskQuery, response: TaskListResponse })
  async index(ctx: any) {
    return tasksService.getAllTasks(ctx.query.limit);
  }

  @Post('/', {
    body: TaskBody,
    response: TaskResponse,
    beforeHandle: AuthRoute,
  })
  async create(ctx: any) {
    return tasksService.createTask({ title: ctx.body.title });
  }

  @Get('/:id', { params: TaskParams, response: TaskResponse })
  async show(ctx: any) {
    return tasksService.getTask(ctx.params.id);
  }

  @Put('/:id', { params: TaskParams, body: TaskBody, response: TaskResponse })
  async update(ctx: any) {
    return tasksService.updateTask({
      id: ctx.params.id,
      title: ctx.body.title,
    });
  }

  @Delete('/:id')
  async destroy(ctx: any) {
    return tasksService.deleteTask(Number(ctx.params.id));
  }
}

const tasksService = new TasksService();
//step3
export default new TasksController(tasksService).start();
//in server.ts add: app.use(TasksController)

Create Turso db

• make sure you already installed Turso CLI

turso db create mydatabasename

Get the db url

turso db show mydatabasename

Get the db token

turso db tokens create mydatabasename

Update the .env file with the token and url from the above commands

bun install

• if you want to switch to local sqlite see this quide

Run the application

To start the development server run:

npm run dev

Open http://localhost:3500/ with your browser to see the result.

make sure in your tsconfig.json you have:

"experimentalDecorators": true
