Ionic app as a part of native app, like a standalone module.
Can I refer this guide to implement it? Have any precautions?
You can embed an ionic app as part of a webview as discussed in that guide.
However you will not be able to use ionic build <platform> you’ll need to copy the www directory manually into your existing application and make sure you reference the directory correctly within your existing application so that it can find the html/JS/CSS etc.
You might also have difficulties with plugins as they are included as part of the cordova build process.
Thanks for reply, I think so too.
