Migrate LocalStorage from UIWebview to ionic webview
This plugin can be used in conjunction with
cordova-plugin-ionic-webview
to persist LocalStorage data when migrating from UIWebView
to ionic's WKWebView
. All related
files will be copied over automatically during startup so the user can simply pick up where they
left of.
How to use
Simply add the plugin to your cordova project via the cli:
cordova plugin add https://github.com/kas84/cordova-plugin-migrate-localstorage
Notes
LocalStorage files are only copied over once and only if no LocalStorage data exists for ionic's
WKWebView
yet. This means that if you've run your app withWKWebView
before this plugin will likely not work. To test if data is migrated over correctly:- Delete the app from your emulator or device
- Remove the
cordova-plugin-ionic-webview
andhttps://github.com/kas84/cordova-plugin-migrate-localstorage
plugins - Run your app and store some data in LocalStorage
- Add both plugins back
- Run your app again. Your data should still be there!
Once the data is copied over, it is not being synced back to
UIWebView
so any changes done inWKWebView
will not persist should you ever move back toUIWebView
. If you have a problem with this, let us know in the issues section!
Background
One of the drawbacks of migrating Cordova apps to WKWebView
is that LocalStorage data does
not persist between the two. Unfortunately,
cordova-plugin-ionic-webview
does not offer a solution for this out of the box.
