Simple Todo API - Adonisjs Typing CST Test
Simple Todo API — Adonisjs Code
Demonstrates a simple AdonisJS controller and model for managing Todo items via REST API.
// app/Models/Todo.js
const Model = use('Model');
class Todo extends Model {}
module.exports = Todo;
// app/Controllers/Http/TodoController.js
const Todo = use('App/Models/Todo');
class TodoController {
async index({ response }) {
const todos = await Todo.all();
return response.json(todos);
}
async store({ request, response }) {
const data = request.only(['title', 'completed']);
const todo = await Todo.create(data);
return response.status(201).json(todo);
}
}
module.exports = TodoController;
// start/routes.js
Route.get('/todos', 'TodoController.index');
Route.post('/todos', 'TodoController.store');Adonisjs Language Guide
AdonisJS is a fully-featured, opinionated Node.js web framework for building server-side applications, APIs, and full-stack web apps with a focus on developer productivity and stability.
Primary Use Cases
- ▸RESTful APIs and GraphQL backends
- ▸Full-stack web applications
- ▸Real-time apps via WebSockets
- ▸Enterprise-scale server-side applications
- ▸Prototyping and MVPs with structured architecture
Notable Features
- ▸Structured MVC architecture
- ▸Built-in ORM (Lucid) for database management
- ▸Authentication and authorization system
- ▸WebSocket support for real-time features
- ▸Queues, caching, and scheduled tasks
Origin & Creator
Created by Harminder Virk in 2015, maintained by the AdonisJS core team and community.
Industrial Note
AdonisJS is often used for building full-stack Node.js applications, APIs, real-time systems, and enterprise-grade backends where consistency, structure, and developer productivity are important.
Quick Explain
- ▸AdonisJS provides a structured MVC architecture with built-in support for routing, ORM, validation, authentication, and more.
- ▸It emphasizes convention over configuration, offering a cohesive and batteries-included ecosystem.
- ▸Supports synchronous and asynchronous programming via modern JavaScript/TypeScript.
- ▸Integrates easily with relational databases, caching, queues, and WebSockets.
- ▸Designed for both small applications and scalable enterprise-grade projects.
Core Features
- ▸Routing and controllers
- ▸Lucid ORM for relational databases
- ▸Middleware and service providers
- ▸Validation and exception handling
- ▸Real-time WebSocket channels
Learning Path
- ▸Week 1: Learn Node.js and TypeScript basics
- ▸Week 2: Understand AdonisJS routing and controllers
- ▸Week 3: Work with Lucid ORM and migrations
- ▸Week 4: Implement middleware, authentication, and WebSockets
- ▸Week 5: Testing, deployment, and performance tuning
Practical Examples
- ▸Build a CRUD REST API with Lucid ORM
- ▸Create a real-time chat application using WebSockets
- ▸Implement JWT-based authentication and authorization
- ▸Schedule tasks with AdonisJS queues
- ▸Integrate third-party APIs and services
Comparisons
- ▸AdonisJS vs Express -> AdonisJS is opinionated and batteries-included; Express is minimalistic
- ▸AdonisJS vs NestJS -> Both TypeScript-friendly; NestJS uses decorators and dependency injection heavily
- ▸AdonisJS vs Koa -> Koa is middleware-centric and lightweight; AdonisJS is full-featured
- ▸AdonisJS vs Sails -> Sails is MVC and ORM-heavy; AdonisJS is modern and TypeScript-native
- ▸AdonisJS vs LoopBack -> LoopBack focuses on APIs; AdonisJS provides full-stack capabilities
Strengths
- ▸Structured and opinionated framework reduces boilerplate
- ▸Batteries-included with authentication, validation, ORM, and more
- ▸Supports TypeScript natively
- ▸Great for enterprise apps with complex backends
- ▸Strong conventions for maintainable code
Limitations
- ▸More heavyweight compared to lightweight frameworks like Express or Fastify
- ▸Opinionated structure may limit flexibility for unconventional architectures
- ▸Smaller ecosystem than Express.js
- ▸Learning curve for beginners unfamiliar with MVC
- ▸Less suitable for tiny microservices
When NOT to Use
- ▸Tiny microservices where minimal overhead is desired
- ▸Projects requiring minimal structure or unconventional architecture
- ▸Node.js apps that prefer lightweight frameworks like Express
- ▸Projects where TypeScript is not desired
- ▸Simple static sites with no backend logic
Cheat Sheet
- ▸node ace new my-app - create project
- ▸node ace serve --watch - start dev server
- ▸node ace make:controller - generate controller
- ▸node ace make:model - generate model
- ▸node ace migration:run - run migrations

Final Summary
- ▸AdonisJS is a full-featured Node.js framework with MVC architecture.
- ▸Provides ORM, authentication, WebSockets, validation, and queues.
- ▸TypeScript-first with a batteries-included philosophy.
- ▸Ideal for full-stack applications, APIs, and enterprise-grade backends.
- ▸Structured conventions improve maintainability and developer productivity.
Project Structure
- ▸app/ - controllers, models, middleware
- ▸database/ - migrations, seeds
