Pub build status

Automatic YAML configuration loader for Angel.


Any web app needs different configuration for development and production. This plugin will search for a config/default.yaml file. If it is found, configuration from it is loaded into app.configuration. Then, it will look for a config/$ANGEL_ENV file. (i.e. config/development.yaml). If this found, all of its configuration be loaded, and will override anything loaded from the default.yaml file. This allows for your app to work under different conditions without you re-coding anything. :)


In pubspec.yaml:

    angel_configuration: ^1.0.0


Example Configuration

# Define normal YAML objects
some_key: foo
  a_string: "string"
  another_string: "string"

You can also load configuration from the environment:

# Loaded from the environment
system_path: $PATH

If a .env file is present in your configuration directory, then it will be loaded before applying YAML configuration.

Server-side Call configuration(). The loaded configuration will be available in your application's configuration map, which means you can access them like normal instance members.

main() {
  print( == app.configuration['foo']); // true

An instance of Configuration will also be injected to your application, and it works the same way:

import 'dart:io';
import 'package:angel_framework/angel_framework.dart';
import 'package:angel_configuration/angel_configuration.dart';
import 'package:file/local.dart';

main() async {
    var app = new Angel();
    var fileSystem = const LocalFileSystem();
    await app.configure(configuration(fileSystem)); // It's that easy!
    app.get('/foo', (Configuration config) {
      return config.some_key;

configuration also accepts a sourceDirectory or overrideEnvironmentName parameter. The former will allow you to search in a directory other than config, and the latter lets you override $ANGEL_ENV by specifying a specific configuration name to look for (i.e. production).

This package uses package:merge_map internally, so existing configurations can be deeply merged.


# default.yaml
  bar: baz
  quux: hello
# production.yaml
  quux: goodbye
  yellow: submarine
# Propagates to:
  bar: baz
  quux: goodbye
  yellow: submarine

In the Browser

You can easily load configuration values within your client-side app, and they will be automatically replaced by a Barback transformer.

In your pubspec.yaml:

- angel_configuration

In your app:

import 'package:angel_configuration/browser.dart';

main() async {

You can also provide a dir or env argument, corresponding to the ones on the server-side.


  • Now using package:merge_map to merge configurations. Resolves #5.
  • You can now specify a custom envPath.
