celest 1.0.1+2

The Flutter cloud platform. Celest enables you to build your entire backend in Dart.

Celest

Celest is the Flutter cloud platform, enabling Dart and Flutter developers to define their backend infrastructure purely in Dart.

Celest offers a simple and intuitive way to define cloud functions, authentication, and database services. With Celest, you can build full-stack Flutter applications with ease, all while using the same language and tools you already know.

Getting Started

To get started with Celest, you need to install the Celest CLI. You can do this by downloading the latest release from our website.

Once you have the CLI installed, you can create a new project by running the following command:

$ celest init

You can run this command from within your Flutter project which will create a new celest/ directory for your project. Or you can run this in another directory to have a standalone Celest project.

Once you have a project, run celest start to start a local development environment.

$ celest start
✓ Celest is running on http://localhost:7777

This command will start a local server which will run in the background as you write your backend logic. As you make changes to the files in the celest/ directory, the server will hot-reload those changes so you can see them live.

To interact with the running environment, Celest will generate a Dart client which you can use in any Dart or Flutter project. This client is generated in the client/ directory of your celest/ folder. As you make changes in the local environment, this client will be updated to reflect those changes.

Example

Here is an example of a simple Celest function:

import 'package:celest/celest.dart';

@cloud
Future<String> sayHello(String name) async {
  print('Saying hello to $name');
  return 'Hello, $name';
}

This function can be called from a Dart project like so:

import 'package:my_project_client/my_project_client.dart';

Future<void> main() async {
  celest.init(environment: CelestEnvironment.local);
  final response = await celest.functions.sayHello('World');
  print(response); // Hello, World
}

In addition to Dart cloud functions, Celest offers authentication and database services out-of-the-box. To learn more about these features, and to see what else you can do with cloud functions, visit our docs.
