cordova-plugin-updater

=============================

Cordova plugin for hot update cordova www/* files.

Tested on android and ios.

Concept:

1. on startup copy all files from www to PERSISTENT storage. (if not copied before);
2. download updater.json from update server.
3. compare the version constants in downloaded updater.json and local updater.json.
4. if different - download new files from server to PERSISTENT, then override local updater.json.
5. redirect window.location.href to PERSISTENT/$start.html;

Attention: Current version requires internet connection on app startup;

dependency :

    <dependency id="cordova-plugin-file" version=">=2.0.0" />
    <dependency id="cordova-plugin-file-transfer" version=">=1.0.0" />
    <dependency id="cordova-plugin-splashscreen" version=">=1.0.0" />

Installation:

Setup Cordova:

  cordova plugin add cordova-plugin-updater.git --variable UPDATE_URL="$UPDATE_URL"

Replace $UPDATE_URL with your server url, where your updater.json and files for update.

Setup updater.json

Write a updater.json to describe files to download and version. Put it in $UPDATE_URL/updater.json; (example http://www.anrip.com/updater.json);

Structure

don't forget to delete comment lines, must be valid JSON

{
  "version": 1, //version, to see if an update is required.
  "start": "index.html", //start page of your app
  "files": [  //an array of new or different files to download
    "index.html", //this file will be downloaded from $UPDATE_URL/index.html
    "image/fon.png" //example
  ]
}

Tips

If server updater.json verison != local updater.json version, the updater wipes the cache, copies all files from www folder to cache, downloads new files, and overrides updater.json.
