API wrapper for [Trafikverket Öppet API](https://api.trafikinfo.trafikverket.se/) writen in TypeScript using built in Node.JS modules where possible to minimise dependencies. This package also aims to implement all available schema versions with correct typings so that future changes to the API wont break existing code.

### Single Shot

This will send a one off query to Trafikverket Open API and return the queries results ending the whole transaction.

### Streaming

This will first send an initial request to Trafikverket Open API like single shot but will then subscribe to Server Side Events and continously emit new updated data.
