Introduction

This is a configuration package for Angular. It allows you to dynamically load a json file at the root of your project. It also provides a provider that allows you to add configuration values in the config function of your Angular app. There is a test app using this Provider to show how to configure and use it.

Requirements

  • npm
  • angular

How to configure

  1. In your project folder, install this plugin using npm npm install git+https://[email protected]/geeklearningio/gl-angular-configuration.git --save

  2. You can use the Typescript (package/src/ConfigurationProvider.ts) or the Javascript ((package/dist/ConfigurationProvider.js)) version of the Provider.

  3. In your application's main module, inject the dependency gl-angular-configuration in order to use the Provider.

angular.module('mainModuleName', ['ionic', 'gl-angular-configuration']){

}

How to use

Dynamically load the configuration.json file (optional)

Add a configuration.json file at the root of your project.

Note: If you look at the webpack config (webpack.base.config.js) of the test-app provided with the package, you'll see that I use the CopyWebpackPlugin to copy the right configuration named after a env argument passed to the webpack cli. The command line I use is a npm script. You can find it in the package.json file of the test-app.

Remove the automatic bootstrap of your angular app. You can do it by Removing the ng-app tag of your index.html file. It will allow you to boostrap it manually after the json has been loaded.

<html ng-app="testApp">

In your application's main module, call the loadConfigurationJSON and pass a callback as a param. In the callback, get the html dom element and bootstrap manually your app.

loadConfigurationJSON(() => {
    var domElement = document.querySelector('html');
    angular.bootstrap(domElement, ["testApp"]);
});

Add a configuration at config state

In the config function of your Angular application, inject the ConfigurationProvider and call the addConfiguration function. You can also add a default configuration by calling addDefaultConfiguration. This function only changes the priority of the configuration loaded. It means that if the current configuration has a "env" param and the default configuration has also an "env" param, then it will keep the param of the current configuration, not the default one. You can specify the type of your configuration object in the Typescript version.

import {ConfigurationProvider} from "gl-angular-configuration/package/src/ConfigurationProvider";

interface ITestAppConfiguration {
    env: string
}

export class Config {
    constructor(configurationProvider: ConfigurationProvider<ITestAppConfiguration>) {
        configurationProvider.addObject({otherParam: 'test'});
    }
}

How to use the test app

the test app does not have the package as a dependency. It allows you to make changes directly to the package and use it in your test app.

You need to link the package locally. At the root of the project (containing the package and the test-app folders) type this in the terminal:

npm link

It will add gl-angular-configuration as a global npm module.

Then go in the test-app folder and type this:

npm link gl-angular-configuration

It will link it to the test-app.
