I'm running my heroku app locally using heroku local web with this being the only line in my Procfile:
web:node index.js
How can I get it to print live logs while running locally?
I found this answer, but there are some things missing from that explanation, and I'm struggling with it, since I'm new to heroku. Any help is appreciated.

I'm trying to deploy a nodejs app on heroku for the first time, but I'm stuck at the command "heroku open" since it gives me an application error and no information as to where it crashed. The app runs locally without problem.
How would you proceed to debug this?
Thanks for your advice and time.
If running heroku local does not help, run a remote shell:
heroku run -a <your app name> /bin/bash, and there run npm start to see the logs and debug the issue on the Heroku server.
When running your app "locally", have you tried running heroku local? This runs the app through Heroku, but on local server.
I have a shiny app and want to deploy it to Heroku. I tried to follow the steps as mentioned in:
https://github.com/btubbs/heroku-buildpack-shiny
I created a git Git repository and put the R files into it. Then, I created an app in heroku and tell Heroku to use a custom buildpack for my app. But, I was not be able to enable Heroku websockets support.
Error is:
Couldn't find that feature.
I can't figure out how to deal with this problem. Is there any other way to deploy the shiny app to Heroku?
Have you seen https://github.com/virtualstaticvoid/heroku-docker-r?
Check out the example shiny app too. To specify additional dependencies, you can still use init.R.
To deploy using Docker, you might have to move your current Heroku app to a container stack. This can be done with the heroku stack:set CLI command:
$ heroku stack:set container
Here's a minimal example. Basically:
Create run.R file with the following
library(shiny)
port <- Sys.getenv('PORT')
shiny::runApp(
appDir = getwd(),
host = '0.0.0.0',
port = as.numeric(port)
)
Commit to git
Create a new heroku app with
heroku create --buildpack https://github.com/virtualstaticvoid/heroku-buildpack-r.git
git push heroku master
That's all there is to it.
Another way would be to deploy using Docker. I am not an expert, but it took me a couple of days to deploy an app using this soluation. Many tutorials exist and could bring you to achieving this.
I am working on a new project that is using heroku, I get this error when I try to run the app locally:
Moped::Errors::ConnectionFailure at / Could not connect to any secondary or primary nodes for replica set <Moped::Cluster nodes=[<Moped::Node resolved_address="127.0.0.1:27017">]>
and I think it has something to do with Heroku because if I type
$ heroku info,
i get this error:
! You do not have access to the app disrupt.
I can't find this error anywhere on the internet, on any forums and there is nothing in the Heroku documentation.
The error normally just means that the MongoDB server is not running locally. Try starting it up by running mongod. Otherwise check you mongoid.yml to see how the development and test environments are set up to connect to MongoDB.
The other error that you get from heroku looks like a separate issue. As tolgap suggests you may just not be authenticated with heroku.
I am trying to deploy a playframework application to Heroku. After deploying, I trying to access the URL Heroku gave me, it only show a welcome page as below :
Heroku | Welcome to your new app!
Refer to the documentation if you need help deploying.
Is any wrong ??
Your app is not recognized by Heroku (Heroku does not know how to start your app).
You need to create a file called Procfile in the top directory of your Play! application:
web: play run --http.port=$PORT $PLAY_OPTS
You will more details in this documentation.
I have a Rails 2 application running well on my local machine at the moment. But fails on Heroku, here's the log: http://pastie.org/1957572
I can't figure out why the path is "app/app/model/.." instead of just "app/model...", is there anything I need to config my Rails app for Heroku?
Thanks!
You probably figured this out, but it's because /app is the root folder for apps on Heroku
It's like if you had it on your own VPS and it was in /var/www, then the error would read like "/var/www/app..."
