localForage-cordovaSQLiteDriver

SQLite driver for Cordova apps using localForage.

Requirements

  • for earlier versions of localforage, please use the v1.2.x releases

Install Dependencies

• install Cordova-sqlite-storage plugin cordova plugin add https://github.com/litehelpers/Cordova-sqlite-storage.git
• install localForage-cordovaSQLiteDriver
  • via npm with: npm i --save localforage localforage-cordovasqlitedriver (ionic 2 users might prefer ths one)

CHANGELOG

v1.3

Reduce driver size (almost by 50%) by "inheriting" the method implementations of the localforage.WEBSQL driver.

v1.2 BREAKING CHANGE

Add support for newer versions of Cordova SQLite storage plugin (v0.8.x & v1.2.x).

UPGRADE WARNING: The default storage location for SQLite has changed in newer versions of Cordova SQLite storage plugin. The new "default" location value is NOT the same as the old "default" location and will break an upgrade for an app that was using the old default value (0) on iOS. If you are upgrading to a newer version of localForage-cordovaSQLiteDriver you need to verify where your previous storage location was and update the location property of the localForage database. Otherwise the default is 'default'. This is to avoid breaking the iCloud Design Guide. See here for further details.

v1.1

Try using the getSerializer() (available in localforage v1.3) as the prefered way to retrieve the serializer.

Setup Your Project

• Include localforage and localForage-cordovaSQLiteDriver in your main html page, after the cordova include.
• Call defineDriver and setDriver to make localForage use the cordovaSQLiteDriver.

<script src="cordova.js"></script>

<script src="lib/localforage/dist/localforage.js"></script>
<script src="lib/localForage-cordovaSQLiteDriver/dist/localforage-cordovasqlitedriver.js"></script>
<script>
localforage.defineDriver(window.cordovaSQLiteDriver).then(function() {
    return localforage.setDriver([
    	// Try setting cordovaSQLiteDriver if available,
      window.cordovaSQLiteDriver._driver,
      // otherwise use one of the default localforage drivers as a fallback.
      // This should allow you to transparently do your tests in a browser
      localforage.INDEXEDDB,
      localforage.WEBSQL,
      localforage.LOCALSTORAGE
    ]);
}).then(function() {
  // this should alert "cordovaSQLiteDriver" when in an emulator or a device
  alert(localforage.driver());
  // set a value;
  return localforage.setItem('testPromiseKey', 'testPromiseValue');
}).then(function() {
  return localforage.getItem('testPromiseKey');
}).then(function(value) {
  alert(value);
}).catch(function(err) {
  alert(err);
});
</script>
