Question

I am trying to deploy a node+express+mongo into heroku.

index.js

const PORT = process.env.PORT || 3200;

const CONNECTION_URL =
  "mongodb+srv://aarthi:C<password>@cluster0.prt4u.mongodb.net/BookMyShow?retryWrites=true&w=majority";

mongoose
  .connect(CONNECTION_URL, { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() =>
    app.listen(PORT, () =>
      console.log(
        `Server Running on Port:https://immense-sands-26614.herokuapp.com/`
      )
    )
  )
  .catch((error) => console.log(`${error} did not connect`));
