Answer 1

Make sure you have these 2 things in place:

1. In your package.json, include heroku-postbuild line, in my case is like this, (it might change if you need to do more than one install)

        "scripts": { 
        "heroku-postbuild": "npm install --prefix client && npm run build --prefix client"
      },

2. In your index.js file, add a condition for production

    if (process.env.NODE_ENV === "production"{
      app.use(express.static("build"));
      app.get("*", (req, res) => {
        res.sendFile(path.resolve(__dirname,  "build", "index.html"));
      });
    }

Express will serve up production assets like our main.js file, or main.css file!

Finally- Express looks if the request is for an asset Express will serve up the index.html file if it doesn't recognize the route
