Description

React Native Debugger app version: 0.7.13 React Native version: 0.51.0 Platform: iOS Is real device of platform: No Operating System: macOS 10.13.2

When I make changes to files in my project these are not reflected in the "Sources" view of RND. I reloaded the app in the simulator and I disabled the cache in Developer Tools Settings (F1) but it does not help. This does not happen if I use the Developer Tools of Chrome to debug.

Research direction
The issue is that changes to .js files are not reflected in the Sources panel of React Native Debugger. The user suspects a caching issue. To investigate, look at how the debugger loads source files, possibly in the Electron main process or the webview's caching behavior. Check the configuration of devTools and any cache control headers. Also examine the React Native debugger's source code at https://github.com/jhen0409/react native debugger for file watching or hot reload logic. Consider setting up a minimal reproduction to verify the caching hypothesis.
