Heroku Cannot GET /

I am new to Heroku and believe I am following all of the steps outlined on Heroku’s website to deploy via node.js – https://devcenter.heroku.com/articles/getting-started-with-nodejs – but despite indications of success, I only see this in the browser when I go to my newly-generated herokuapp.com site.

Cannot GET /

No errors when executing

git push heroku master

My Procfile is simply

web: node app.js

I dont quite understand dynos yet, but there seems to be one running:

heroku ps
=== web (1X): node app.js
web.1: up 2014/07/03 23:55:00 (~ 18m ago)

Then:

heroku open
Opening APP-NAME… done

But https://APP-NAME.herokuapp.com/ just displays the Cannot GET / message.

    I had my dist directory included in my .gitignore file so I was not committing dist to my repo and not pushing it to Heroku. Therefore, Heroku could not find any content to serve.

    I updated my .gitignore, committed, and pushed, and my app shows up just fine on Heroku now.

    almost 3 years, but I’m answering for reference.

    • generally /dist is a build process generated directory, it’s temporary and changes a lot while working in our sources, so /dist is not versioned.
    • on your package.json you can add a script called postinstall with this build process, let’s say you have a task in gulp called build…so “postinstall”: “gulp build”
    • if you manage your project’s dependencies in bower too, npm install –save bower and “postinstall”: “./node_modules/bower/bin/bower install && gulp build”

    Just a simple example croped for your package.json

    {
       "dependencies: {
        "bower":"^1.8.0",
        "grunt":"^1.0.1",
       },
       "scripts": {
        "start": "node ./www.js",
        "build": "grunt dist",
        "postinstall": "./node_modules/bower/bin/bower install && npm run build"
       }
    }
    

    Obvious you’re probably done and better nowadays…I’m just referencing it for next consultings.
