This project was a proof of concept written in Typescript, using the NS (dutch railroad company) API, to build a travel assistent app that would pro-actively help the user to find the next best connection if they miss their train, or if their selected train was cancelled or delayed.

The backend was built using [NodeJS](/nodejs)/Express and Apollo [GraphQL](/graphql) server and the frontend was made with [React](/react) and [MUI](/mui).

Some code samples and screenshots of the app are available through this gist: [https://gist.github.com/brense/bafdbcf0b656bb101be3ab5c31242ea9](https://gist.github.com/brense/bafdbcf0b656bb101be3ab5c31242ea9)
