I have a node.js/express app, I would like to run the command gulp build to generate my static assets when deploying with heroku, just before my node command lcm server, as I keep my public folder in my .gitignore file.
I'm having trouble finding how I can run this command during my heroku deployment.
So far my Procfile is:
web: lcm server
This doesn't seem to work -
gulp build
web: lcm server
Make a Procfile
Begin by making a blank file named Procfile and placing it within the root of your project. Procfile is short for “Process File” and used to explicitly declare what command should be executed to start your app. By default, a Procfile is not required, but it’s good form for Node-based projects to create one.
If a Procfile isn’t defined, then one will be created automatically using npm start as the web process type.
Possible solution
Try this one:
web: node node_modules/gulp/bin/gulp build
The line above lets us use the locally installed version of Gulp provided by Node’s Package Manager (NPM) instead of having to use a globally installed version.

I always create a file called server.js as entry point of my Node.js app and I always deploy to Heroku with that file but... How does Heroku know that server.js the file that it should to execute?
What if my server file is called anotherName.js? How can I tell to Heroku to deploy anotherName.js?
If you have a Procfile, Heroku will look there first.
If no Procfile exists, Heroku will try to run the start sript defined in your package.json.
What if my server file is called anotherName.js? How can I tell to Heroku to deploy anotherName.js?
Either by modifying (or creating) your Procfile or by changing the start script in your package.json.
I'm trying to deploy an application through Heroku which is just an index.html page with some javascript and css.
I've connected my Github repository to it as a deployment method, but it never seems to work.
Every time I type "heroku logs", it spits back out:
"npm ERR! missing script: start" first.
From what I've searched, it tells me that I need to add "start": "somefile.js" as a starting point in package.json, but this is a very simple index.html page with javascript invoked from whenever a couple buttons are pressed.
How am I meant to get past this?
Heroku isn't really built for hosting static websites that have no dynamic server backend. If you want to do that, you should look into using a proper static file host like Amazon S3, Netlify, etc.
However -- if you DO want to do this on Heroku, you can do so by creating a really simple application (here's an article which shows you how to do it using Ruby): https://devcenter.heroku.com/articles/static-sites-ruby
Agree with #rdegges, you need some sort of http server. A basic node http server is pretty trivial to implement as well.
A full tutorial is available, but the keys steps are:
Make sure you have [node, npm, heroku CLI] installed.
In the root of your project directory, run npm init - (this will create a package.json in your root project directory)
Run npm install --save express - (this will add express as a dependency to the package.json file)
Create a file named Procfile in the root directory.
(contents: web: npm app.js)
Create a file named app.js in the root directory. (contents below)
Commit your changes, push to Heroku - git push heroku master
That should do it. Make sure all your files are in a directory called public as specified in the app.js file or change that to reflect where they actually are.
app.js:
var express = require('express');
var app = express();
app.use('/', express.static('public'));
app.listen(process.env.PORT || 8080);

I created a app for Angular manually, his structure and all stuff.
To run it locally I'm using http-server.
How can I deploy it to Heroku in order to inform what server to run (probably in Procfile)?
Create a Procfile just called Procfile (no extension) in the root of your app. Within that file use web: to tell heroku what to run. For example:
web: coffee server.coffee
I have seen very similar posts, that however did not help me to find a solution to my problem.
I am following step by step the guide to upload a project on heroku.
However when I type the command:
ps:scale web=1
The result is:
no such process type web defined in Procfile
I have created a file "Procfile" being careful at the capitalization. but nothing.
What else can I do to solve this problem??
Thanks in advance.
Follow on this heroku procfile
:
We have to define web process type in your Procfile and make sure name Procfile exactly, and not anything else. For example, Procfile.txt is not valid.
Example:
a: Python:
web: gunicorn gettingstarted.wsgi --log-file -
b: String MVC Hibernate
web: java $JAVA_OPTS -jar target/dependency/jetty-runner.jar --port $PORT target/*.war
This declares a single process type, web, and the command needed to run it. The name web is important here. It declares that this process type will be attached to the HTTP routing stack of Heroku, and receive web traffic when deployed.
Procfiles can contain additional process types.
worker: bundle exec rake jobs:work
Hopefully you've fixed your problem after all this time, but just in case you haven't...
I've run into this problem when my Procfile doesn't exist (a web app that I'm porting to Heroku) or doesn't match the dyno type that I'm trying to deploy (see Heroku No such process type web defined in procfile for an example of that).
You've created your Procfile, but what did you put in there? For a website Node.js app, you'll need to put in:
web: node app.js
(Obviously you'll replace app.js with index.js or wherever your app starts)
For more about Procfiles (or for other languages than Node.js), see https://devcenter.heroku.com/articles/procfile
Has anyone tried deploying a Revel app using Dokku?
I tried "https://www.digitalocean.com/community/tutorials/how-to-use-the-dokku-one-click-digitalocean-image-to-run-a-go-app" and it deployed successfully.
However, when I try a new Revel app, it gives me this error
remote: mv: cannot stat `/build/app/.heroku/g/bin/*': No such file or directory
This is the .godir that I created:
myappname
This is the Procfile:
myappname
What am I doing wrong?
Thanks
Since Revel is a web app (receiving incoming HTTP traffic), you need to declare a web process type in your Procfile, i.e.:
web: myappname ## Procfile requires a Unix process declaration
This tells Dokku what command to run to start the web process on the server -- in this case myappname.go in your project root.
Leave off the .go file extension in the Procfile.
Dokku is a "Docker powered mini-Heroku" so Heroku's support docs are relevant:
The unix process model is a simple and powerful abstraction for running server-side programs. Applied to web apps, the process model gives us a unique way to think about dividing our workloads and scaling up over time. The Heroku Cedar stack uses the process model for web, worker and all other types of dynos.
-- from Process Types and the Procfile - Heroku Dev Center
Note that the standard Go Buildpack for Heroku/Dokku needs either a Godeps directory, or the deprecated method of including a .godir file.
You need to use the revel buildpack instead of the Go one. The buildpack will generate the Procfile for you.
Be sure to:
Add a .env file with this in your project: BUILDPACK_URL=https://github.com/revel/heroku-buildpack-go-revel.
Add a .godir file with the argument you use to run your app, e.g. github.com/yourcompany/yourrepo.
