Setup

docker pull mongo:4.1.9-bionic
npm install
docker run --rm -p 27017:27017 --name mongo-9k -v $HOME/mongo-9k:/data/db -d mongo:4.1.9-bionic

Load data

Login to github; goto settings; generate a personal access token. Write the token to github-token.txt (don't commit this file!). Then run load_data.js with the token passed as an environment variable.

token=`cat github-token.txt` node load_data.js

To see the map data, you need a google key. Login to google maps api and get a javascript maps API key. Enable the javascript maps API and the geocoding API. Restrict the key to only use these 2 APIs. Write it to a file called public/google-maps-key.txt. You'll need to provide credit card details to google to get the key.
