Heroku Error: ENOENT, stat '/app/build/index.html'

Question

I'm trying to deploy to a hero, but Im getting Error: ENOENT, stat '/app/build/index.html' when I go to my address. Otherwise, deploying the application does not give me any error. Can someone explain what I'm doing wrong. Here is my code and code structure.

server.js

 var express = require('express'), server = express(), bodyParser = require('body-parser'), logger = require('morgan'), methodOverride = require('method-override'); // for heroku var port = process.env.PORT || 5000; server.use(express.static(__dirname + '/build')); server.use('/src', express.static(__dirname + '/build/src')); // js server.use('/assets', express.static(__dirname + '/build/assets')); // css, images server.use('/vendor', express.static(__dirname + '/build/vendor')); // other server.use(logger('dev')); server.get('/', function(req, res, next) { res.sendfile('index.html', { root: __dirname + '/build' }); }); server.listen(port, function() { console.log("Listening on " + port); });

Answer 1

Figured it out. This was my .gitignore file, in which I included the /build folder.

Answer 2

Try something like this:

 res.sendfile( __dirname + '/build/index.html' );
