Cannot get route when deployed to heroku

Your config has been working great so far locally. When i deployed it to Heroku i started getting the following issue:

If i go to https://enjoy-copenhagen-dev.herokuapp.com everything is fine, i can navigate through the app, no issues there.

If i go to https://enjoy-copenhagen-dev.herokuapp.com/api or whichever one of my api post and get endpoints everything works.

If i try to open any other route i get Cannot GET /route-i-tried-to-open.

My server.js

const cors = require('cors');
const path = require('path');
const express = require('express');
const nodemailer = require('nodemailer');
const bodyParser = require('body-parser');
const app = express();

const mail = require('./emailSenders');

app.use(cors());

app.use((req, res, next) => {
  res.header('Access-Control-Allow-Origin', '*');
  res.header('Access-Control-Allow-Methods', 'DELETE, PUT, GET, POST');
  res.header(
    'Access-Control-Allow-Headers',
    'Origin, X-Requested-With, Content-Type, Accept'
  );
  next();
});

// support json encoded bodies
app.use(bodyParser.json());
// support encoded bodies
app.use(bodyParser.urlencoded({ extended: false }));

app.set('port', process.env.PORT || 3001);

// Express only serves static assets in production
if (process.env.NODE_ENV === 'production') {
  app.use(express.static('client/build'));
}

app.get('/api', (req, res) => {});
app.post('/api/createCustomer', (req, res) => {});
app.post('/api/retrieveCustomer', (req, res) => {});
app.post('/api/createCharge', (req, res) => {});
app.post('/api/sendEmail', (req, res) => {});

app.listen(app.get('port'), () => {
  console.log(`Find the server at: http://localhost:${app.get('port')}/`); // eslint-disable-line no-console
});

The solution is to make sure you have this in your server:

if (process.env.NODE_ENV === 'production') {
	app.use(express.static('client/build'));
}

And also add this:

app.get('*', (request, response) => {
	response.sendFile(path.join(__dirname, 'client/build', 'index.html'));
});

You can’t serve a static single page application with dynamic routes without an express server set up this way.

@sudhaparayil Try this:

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

What is ‘client’ and ‘build’ ??
