Building, Running, and Deploying

Background

This app uses React-Redux to build a Jekyl-consumable static page that gets sucked up Github Pages and turned into a single-page app. All of the commands will be run from targets defined in package.json using yarn run.

Building Dev

Prereqs:

• Install Node
• Install NPM
• Install Yarn
• Install Ruby
• Run yarn install
• Run bundle install

Two commands are required to get your local build running: dev:wds and dev:start

dev:wds starts the webpack dev server, which builds and packs the site into a bundle.js that the Jekyll server can use. It hosts this file at localhost:8080 by default, but if you have something else running there it can bump to port 8081.

Running Dev

dev:start starts the Jekyll server. Locally, the Jekyll server uses _config.dev.yml to figure out where the bundle.js content is.

Running these two commands in separate terminals will provide a seamless dev env with hot-reloading of the UI

Deploying

One file is required in order to update prod. that's the bundle.js, but it needs to be the one that GitHub Pages can access. The prod:build command builds the appropriate file. This file must be pushed up. When it is (or when a PR merges it into master), GitHub Pages will recognize it and trigger a new build.

In Short

Running Locally

Assuming all library dependencies are installed, run the following commands in separate terminals:

• yarn run dev:wds
• yarn run dev:start
• Navigate to localhost:4000
