Via trial and error and using the heroku rollback it seems that the problem isn't in my app.js file but in the node_modules. However I can't seem to find a fix. I've tried reinstalling the node_modules.
It works locally but not when I deploy it on Heroku.
also suddenly I have a package-lock.json file. perhaps thats is a clue?

It's complaining about the decimal128 module, I would double check the relative path to the module from the file that is requiring it. Looks like right now it's looking for it in the same folder as the file "/decimal128".

I fixed it myself by going through everything updating everything and downgrading mongodb to "mongodb": "2.2.33"

Error while deploying project to heroku "return process.dlopen(module, path.toNamespacedPath(filename))"

While I was able to push successfully my master branch to Heroku and Heroku confirms my app is deployed successfully, yet, the app is not deployed despite that is shows below deploy success message: "Deploy to Heroku".
This is the whole console when log the error.

Error: Cannot find module 'polka' on Heroku

I'm trying to deploy my sapper/svelte app to heroku but getting 'Error: Cannot find module 'polka'' this error. Interesting thing is that, it was perfectly fine and working. My package.json is correct and I am not checking my modules into git either. I tried disabling caching but it is no good. Anyone have any ideas?

It turns out polka's version on my package.json was set to 'next'. So I changed it to it latest stable version and deleted package.lock.json file and ran 'npm install' to create a new lock file and then pushed it to heroku. Works perfectly fine.

How to set up nodebootstrap at Heroku?

I'm using nodebootstrap to start a new nodejs project (http://nodebootstrap.io/) and it's running fine locally. But when I tried to deploy it to heroku, it showed me the follow errors:

Anybody has any idea how to fix this?
Problem solved - I have some unresolved dependency issue that I didn't found when running locally in dev mode

Deployment of a MEAN stack full app to Heroku

I have successfully deployed some simple nodeJS applications using the Heroku platform.
Now I want to deploy a full application using:
1) a MongoDB database hosted at MongoLab;
2) AngularJS+Bootstrap for the front-end component;
Is this possible to deploy to Heroku?
If so, what changes do I need to apply to the git repo and the Procfile to make it work?
Right now, my github repo looks like this:
Is this the correct structure?
I'm aware of the need to listen on: process.env.PORT instead of a fixed one and I'm also aware of building the package.json automatically using npm init.
For some reason, I can't deploy and I get this error log:

Error with mongodb driver on Heroku: Cannot find module 'mongodb-core'

I've tried various versions of mongodb driver, to no avail.
if you use mongodb-core, you should specify it in package.json like here:
"dependencies": {
"express": "~4.9.x"
, "pg": "~4.4.x"
, "mongodb": "2.0.14"
, "mongodb-core": "~1.0"
},
after pushing it to git, check the log:
remote: -----> Build succeeded!
remote: ├── express#4.9.8
remote: ├── mongodb#2.0.14
remote: ├── mongodb-core#1.0.5
remote: └── pg#4.4.1
