Migrate LocalStorage data from UIWebView to WKWebView
npm install cordova-plugin-ionic-migrate-localstorageThis 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.
Simply add the plugin to your cordova project via the cli:
``sh`
cordova plugin add cordova-plugin-ionic-migrate-localstorage
- LocalStorage files are only copied over once and only if no LocalStorage data exists for ionic's WKWebViewWKWebView
yet. This means that if you've run your app with before this plugin will likely not work.cordova-plugin-ionic-migrate-localstorage
To test if data is migrated over correctly:
1. Delete the app from your emulator or device
2. Remove `
`
cordova plugin rm cordova-plugin-ionic-migrate-localstorage
cordova-plugin-ionic-webview
3. Remove the `
`
cordova plugin rm cordova-plugin-ionic-webview
4. Run your app and store some data in LocalStorage
5. Add both plugins back
``
cordova plugin add cordova-plugin-ionic-webview@1.1.16
`
`
cordova plugin add cordova-plugin-ionic-migrate-localstorage
6. 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 to UIWebView. If you have a problem with this,
let us know in the issues section!
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.
This plugin is a fork of a fork of a copy of the Telerik WKWebView source, so all props go to someone else. #open-source
