Node.js with a quick application crash on Heroku, works locally

Question

I have Node.js with express launch normally locally, but it crashes when I try to run it on Heroku.

When I deploy and go to the heroku subdomain:

• HTML loading but no CSS
• When updating, nothing loads and I get a general application error
• Looking at the logs, it seems that the application crashed.

Any ideas why the hero continues to crumble? The best guess is related to my static files.

Here are the logs:

Here is my package.json:

 { "name": "myapp", "version": "0.0.1", "engines": { "node": "0.10.26", "npm": "1.4.20" }, "scripts": { "start": "node app.js" }, "dependencies": { "express": "~4.2.0", "body-parser": "^1.4.3", "node-compass": "0.2.3", "ejs": "~1.0.0", "express-ejs-layouts": "~1.1.0", "mailgun-js": "^0.5.1" } } 

I have css and js in a shared folder, and I have this line in app.js:

 app.use(express['static'](path.join(__dirname, 'public'))); 

Answer 1

I moved the line of code referring to static files (express.static) up above the other lines of code, and now it works fine on Heroku.

 app.use(express.static(__dirname + '/public')); app.engine('html', require('ejs').renderFile); app.set('view engine', 'html'); app.set('layout', 'layout'); // defaults to 'layout' app.use(require('node-compass')({mode: 'expanded'})); app.use(expressLayouts); app.use(bodyParser.urlencoded({ extended: false }));
