Additional Details, how to run locally

It is good to follow Heroku's node.js tutorial to get an understanding of how node.js works on Heroku and to configure your local environment.

Grab a copy of the code

You'll want to create your own .env file with the MongoDB URI in it:

MONGODB_URI=mongodb://<<username>>:<<password>>@<<your instance>>.mlab.com:<<port number>>/<<your instance>>

Run npm install in the directory you've downloaded

There is a launch.json file part of the project to make it easy to debug with VSCode, run in VS code and look at the Debug Console to see what port it is running at (typically 5000) open your web browser to http://localhost:5000 and view it locally.

Troubleshooting Helpful notes:

Error Logs

To view error logs:

heroku logs --tail -a <<appname>>

Kill Local Instance

To kill the local development environment:

Sometimes the local heroku development enviornment may die in the background, this stackoverflow tip was helpful:

Lists all processes on port 5000:

lsof -i :5000 

Find the PID and then kill the process with this command:

sudo kill -9 <<pid>>

Best Performance

For best performance, ensure that the app is running in production mode (it should be already by default):

heroku config:set NODE_ENV=production -a <<your app aname>>

Special thanks to the following tools and utilities:

The puppeteer buildpack used to scrape trailhead profiles:

heroku buildpacks:set jontewks/puppeteer

Node JS:

heroku buildpacks:set heroku/nodejs

Additional Addons:
