Looking for ExpoAPI allows to read/write at runtime

Hello, I’ll try to be brief about my situation:


  1. SDK Version: latest
  2. Platforms(Android/iOS/web/all): mobile devices


An app needs to load translation files (text type, JSON format) at runtime. And these translation files should be created by a program in dev runtime.


  • Dev stage:
    • Write files to project directory at the dev runtime. This feature only work in dev stage, so it should be understand like write files to the computer of the developers. These files later will be bundled to app for prod usage.
  • Prod stage:
    • Read files from the bundle at the prod runtime. Assuming the files to read is already bundled to the app but not loaded yet and waiting for app load it.

Is there anyway to do this? Thanks in advance.
