redux-immer | Redux combineReducers | State Container library

I was using create-react-app + JSX, so i had to open two terminals one for npm start (on port 3000 for react server) and one for node server.js (for backend on port 4000) and these two are connect through the proxy that i had on my package.json. when i have finished with development, all i had to do was:

1. remove the proxy from package.json.

2. npm run build, which makes a copy of all my code into the build folder.

3. app.use("/", express.static("build")); in my server.js file to make the build folder accessible to app.

4. app.all("/*", (req, res) => { res.sendFile(__dirname + "/build/index.html"); }); at the end of the server.js to catch all.

hope this saves some of your time.
