Key Information

The challenge is finished.

Challenge Overview

Describe what you want to accomplish. 

This challenge is part of a new project involving React Native.  The eventual goal is to have a way to build React Native apps for Hercule's embedded devices that communicate with the device over websockets, using the proprietary XRE messaging protocol.  They would like to see if we can build a React Native piece that sits on a server and communicates with clients, sending them XRE messages to draw the React Native components.

Basically, we are going to stream apps to a client and update the client based on actions that raise events from the client to the server.


We have an existing codebase that implements some portions of what we are eventually going to want to see.  This challenge will clean up and formalise some parts of it and will also add a few new features.


These tickets compose the requirements for this challenge:


The server side "screens" will be implemented in React Native, using React classes. 
The goal is to make sure the React Native definition is generic, not custom to XRE.  The normal React Native development process will apply on the server.


In the forum is the XRE specification.  It has a section called "Establishing the XRE Connection" that should be followed for the connection flow.  In addition, you can use Charles to see the messages sent back and forth between the HTML XRE Receiver provided and the remote server to get an idea of the flow as well.

Native validation

To prove out the solution, we need to ensure that a native mobile build of an app matches what is displayed in XRE.  Please provide documentation on how to compile each example and run it in Android or iOS, and please also provide this information as part of your submission video.


Your submission should be a patch file in Git against commit hash 

NOTE:  You are free to change, reorganize, and refactor the code as you see fit.  You are not required to stick to any past decisions on architecture.

Please make sure your updated README covers:

1.  How to deploy the server-side to Heroku
2.  How to configure the client XRE receiver to connect to the server and work with the different apps available
3.  What the React Native app looks like

A video is required, but it only needs to cover the validation (XRE and native), not the setup.  Having the setup details only in the README is fine.
