import React, { Component } from 'react'
import Turbolinks from 'react-native-turbolinks'

export default class App extends Component {

  componentDidMount() {
    Turbolinks.addEventListener('turbolinksVisit', this.handleVisit)
    Turbolinks.addEventListener('turbolinksError', this.handleError)
    Turbolinks.startSingleScreenApp({url: 'http://MYIP:9292'})
  }

  handleVisit = (data) => {
    Turbolinks.visit({url: data.url, action: data.action})
  }

  handleError = (data) => {
    alert(data.description)
  }

  render() { return null }

Running the Demo

This repository includes a demo application to show off features of the framework. The demo bundles a simple HTTP server that serves a Turbolinks 5 web app on localhost at port 9292.

To run the demo, clone this repository to your computer and change into its directory. Then, Open file Example/app.json and change baseUrl with your IP and start the demo server by running Example/demo-server from the command line.

Once you’ve started the demo server, explore the demo application in the Simulator by running react-native run-ios or react-native run-android on Example folder.
