Using Firebase Database (with Imported JSON file) in Ionic

I’m new to Firebase and I previously had a JSON file consisting of data I was using in my app, this JSON file was hosted on my own sever - and was working well with my app. Now I’d like to expand the app and try using Firebase to enhance it. I’ve gone ahead and created a new account and all and imported my JSON file into firebase, now I’d like to know how I can possibly retrieve this data - I know that simply changing the path to my JSON file might not just be it! Can anyone assist?

Thanks & Regards…

There’s a plugin:
