rewo 1.0.5

Rewo — a modular Dart backend framework. REST APIs, DI, JWT auth, OpenAPI, hot-reload dev, and CLI project scaffolding. Spring-inspired, Express-simple.

Rewo (rewo)

Spring power. Flutter simplicity. Express ease.

Rewo is a modular Dart backend framework for building REST APIs. Scaffold a new project in one command, add modules, compile to a native binary — one server, all APIs included.

Install

Add to your pubspec.yaml:

dependencies:
  rewo: ^1.0.5

Or scaffold a full project with the CLI:

dart pub global activate rewo
rewo create my_api

Or scaffold without global install (from any project that has rewo):

dart pub global activate rewo
rewo create my_api

---

Quick start (new project)

rewo create my_api
cd my_api
dart pub get
cp .env.example .env

Development (hot reload)

rewo run --dev

Or the equivalent:

rewo dev

Optional custom port:

rewo run --dev 3000

Production

rewo run

Optional port:

rewo run 3000

Production binary (deploy)

dart compile exe bin/server.dart -o server
./server

Requires global CLI once:

dart pub global activate rewo

Your project layout:

my_api/
  bin/server.dart       # entry point
  bin/dev.dart          # hot-reload dev server
  lib/app.dart          # register modules here
  lib/modules/          # your API modules
  test/
  .env

---

Add an API module

// lib/modules/hello_module.dart
import 'package:rewo/rewo.dart';

class HelloModule implements RewoModule {
  @override
  String get name => 'hello';

  @override
  void register(Rewo app) {
    app.get('/api/hello', (_) async => {'message': 'Hello World'});
  }
}

Register in lib/app.dart:

static List<RewoModule> get modules => [
  HelloModule(),
];

Minimal app (no scaffold)

import 'package:rewo/rewo.dart';

void main() async {
  await Rewo.run((app) {
    app.get('/hello', (_) async => {'message': 'Hello World'});
  }, config: AppConfig(port: 8080));
}

---

Configuration (.env)

PORT=8080
HOST=0.0.0.0
ENV=development
JWT_SECRET=change-me-in-production
SERVER_ENGINE=native
STORAGE_PATH=./storage

---

Run the server

Requires dart pub global activate rewo once.

Development (hot reload)

rewo run --dev
# or
rewo dev

Saves in lib/ restart the server automatically. Custom port: rewo run --dev 3000.

Production

rewo run

Custom port: rewo run 3000.

Deploy (compiled binary)

dart compile exe bin/server.dart -o server
./server

Place .env next to the binary, or set PORT, JWT_SECRET, etc. in your environment.

Commands

rewo create my_api                        # scaffold project
rewo run --dev                            # dev — hot reload
rewo dev                                  # same as rewo run --dev

rewo run 3000                             # production on port 3000
dart compile exe bin/server.dart -o server   # build binary
./server                                  # run compiled binary
dart test                                 # tests
