• before-suspense is the initial state of the application.
• conf-talk-progress is where we end up--the final state of my talk--so you can follow along.
• after-suspsense is a version where every single thing that can be moved to suspense, has been moved to suspense. I did not get this far in my talk, but it's there for completeness / reference.

cd conf-talk-progress
yarn start

Note the Ken Wheeler and Wale routes do not work. I didn't bother making fake data for them. Sorry. Only the Drake and Big Sean routes work (first 2 results).

In the patches directory, there is a patched version of CRA's config/webpackDevServer.config.js that adds a little express middleware that will delay the high-res images from loading for demo purposes. It sniffs any requests including with -hd.jpeg and waits for the value of delay query parameter. The <Debugger /> request latency slider is used to set this query parameter's value for all images.
