Updating json files once installed on device

I am creating an Ionic app and there are few json files in the www/dataFiles folder. I need to package these files with the app. However, once installed on the device these json files need to be updated periodically with new data from a server. I was searching for days trying to figure out how to do it and I found out that files in the www folder cannot be rewritten. I have no clue how to move forward. Do I have to save files in a different location? I would really appreciate if you can point me in the right direction.

Thank you in advance.

You can update your app and content using IONIC deploy. This would allow you to update the files in www/dataFiles as well. Another option is to use the ContentSync plugin and store your JSON files in the device’s filesystem. There’s a nice article about how to use this plugin on Raymond Camden’s website here.
