Data structure for react app

I have written in react tool for Satifactory game, which is just serverless one-page manager. The tool have something like "inner database", which is holding info about game objects, like buildings and recipes.

Now it is only a JSON files where is everything stored. But I am thinking...

If there some sort of database for react, where I could write these data? I would like something which will be a little more easier to maintain.
