Developer docs

This is a browser app, written in javascript. The primary technologies we use are React, the HTML 2d canvas API, and RxJS. We use babel for es6 support, and webpack for the build.

The application architecture looks a lot like redux, but was developed before redux was a thing. So, we can use redux dev tooling, and the reselect lib, but we currently do not use redux itself. The async model is in the direction of redux-observable, with action side-effects invoking rx streams that will then dispatch later actions.

• Architecture overview
• State updates, in detail
• Debug strategies, widget hierarchy, etc.
• Writing an action handler

Build

The build is based on npm and webpack.

• Ensure that git and node are installed
  • On OSX, install brew http://brew.sh/
  • brew install git
  • brew install node
• git clone https://github.com/acthp/ucsc-xena-client.git
• cd ucsc-xena-client
• npm install
• npm start
• browse to http://localhost:8080/webpack-dev-server/heatmap/

There may be npm warnings about missing redux libraries, but these can be ignored. We're not using redux. We're just using redux tooling.
