Digitransit-ui

Digitransit-ui is a mobile friendly User interface built to work with Digitransit APIs.

Service Architecture

Application is built with React. React components can access data in two different ways:

  • Routing-API queries with Relay
  • Other API with Flux model

Basically, division between alternatives is:

  • GraphQL is used to fetch data from server
  • If server endpoint does not support GraphQL, flux can be used to retrieve that data
  • Flux stores are mainly used to store application state

Installation

Installation instructions are available at GitHub

Tests

Tests run automatically in Browserstack:
