Why Tunder?

Tunder is a framework for creating server side apps that are easy to use and easy to maintain. It was heavily inspired by some famous frameworks like Laravel for PHP, Ruby on Rails for Ruby and Adonisjs for Node.js. So Tunder was created to be the referenced framework for Dart language.

Tunder at a Glance

Keep reading this page if you want to take a look at a brief summary of how to use Tunder as your backend framework for dart language.

Route System

Tunder has it's own route system implemented from scratch using the core dart:io library. Here is how you can define your routes:

web() {
  Route.get('/', () => 'Hello World');
  // or
  Route.get('/', HomeController, 'index');

Tunder will automatically create an instance of the HomeController class and inject all dependencies needed into it.

Why do we use dart:mirrors?

There is a known issue with mirrors library from the Dart team that we are aware of. However we are still using mirrors because we need reflection system in Dart, and for now, mirrors is the only option to use reflection without generators. We don't use generators because they don't provide a good Developer Experience (DX) and overtime increases build time to your app which is something that we're avoiding at most. Read this issue on Github for further details and examples about using mirrors, it's pros and cons etc.


Controllers is one important peace of a MVC framework like Tunder. Here is how a controller looks like:

import 'package:tunder/http.dart';

class HomeController extends Controller {
  index() {
    var date = 3.days.ago; // did you know that you can use dates like this? Looks like rails right? ;D

    return 'Hello World! Three days ago was: ${date}';

Database Migrations

Tunder provides a database migration system out of the box and here is sample migratino for the users table:

import 'package:tunder/database.dart';

class Migration_2022_08_08_143401 extends Migration {
  final id = '2022_08_08_143401';
  final name = 'Create users table';

  up() async {
    await Schema.create('users', (table) {

  down() async {
    await Schema.drop('users');

Database Queries

Let's retrieve the users table you could create in a new controller for users:

import 'package:tunder/database.dart';
import 'package:tunder/http.dart';

class UsersController extends Controller {
  index() async {
    final query = Query('users')

    return query.paginate();

This will return a json string in the following format:

  "data": [
      "id": 1,
      "name": "John Doe",
      "email": "",
      "created_at": "...",
      "udpated_at": "...",
      "deleted_at": null
  "meta": {
    "currentPage": 1,
    "perPage": 10,
    "total": 15,
    "from": 1,
    "to": 10,
    "lastPage": 2,


The middleware system is super simple and works out of the box with the Routing sysmtem. Actually, the routing system was designed with Middlewares in mind. So here is an example of a Middleware class:

import 'dart:async';

import 'package:tunder/http.dart';

class ExampleMiddleware extends Middleware {
  FutureOr<Response> handle(Request request, next) async {
    // do something before the request is handled
    Response response = await next(request);
    // do something after the request is handled with the response
    return response;

Now, here's how you can use your new middleware in your routes definitions:

web() {
  Route.middleware(ExampleMiddleware).group(() {
    Route.get('users', UsersController, 'index').name('users.index');'users', UsersController, 'store').name('');
