System prerequisites

Neo4j v3.5.x needs to be installed, up and running [?]
Neo4j plugin APOC needs to be installed and not restricted [?]
Node.js v8.x should be used (greater major versions might work)
Managing multiple Node.js versions is fairly simple with nvm [?]
Using npm in favor of yarn is recommended for this project
Nginx and pm2 should be used when the app runs remotely [?]

Environment setup

See the configuration values in .env file. It's recommended to copy this file and name it .env.local because that's ignored by Git. The SMTP setup is optional. By default all emails are sent to Ethereal for debugging and the respective URLs are being logged in the server console.
