gulp-ionic-channels

Information

This plugin facilitates the handling of Ionic Platform's deploy channels to use a single codebase for several versions of your application.

Usage

This plugin is best used when piped with gulp-ng-constant to generate angular constants such as the deploy channel.

Gulpfile example

gulpfile.js

var gulp = require('gulp');
var ionicChannels = require('gulp-ionic-channels');
var ngConstant = require('gulp-ng-constant');
 
 
gulp.task('config', function() {
  gulp.src('./config.json')
  .pipe(ionicChannels({
    channelTag: 'staging'
  }))
  .pipe(ngConstant())
  .pipe(gulp.dest('.'));
});

Input configuration

config.json

{
  "staging": {
    "appId": "fr.theodo.updaty-staging",
    "appName": "Updaty Staging"
  },
  "prod": {
    "appId": "fr.theodo.updaty",
    "appName": "Updaty"
  }
}

Javascript Output

Piping this plugin with gulp-ng-constant will allow the generation of a javascript file containing constants included in the requested deploy channel (from the input configuration), along with the version from your package.json file and the tag of the channel itself.

Apart from the 'Multiple Environments' section of their documentation (which is incompatible with our plugin as it is already handled by it), the other options can be used with no issue.

config.js (output)

angular.module("config", [])
 
.constant("appId", "fr.theodo.updaty-staging")
 
.constant("appName", "Updaty Staging")
 
.constant("version", "0.0.1")
 
.constant("channelTag", "staging")
 
;

Special thanks

Thanks to the developers/maintainers of gulp-ng-constant, as most of their code was used to create the skeleton for this plugin.
