Implementation of my thesis project, Unstable Label - a speculative data labeling application.

Starter create-react-app and Express

Glitch only serves content on one port. This is typically not an issue, unless you're trying to run both a webpack development server for front-end work and a back-end server in the same project, at the same time — you get one port for serving resources, but both the front-end and back-end servers each want their own port! This is a common scenario when you're building your front end with create-react-app, and your back end with Express.

This starter app will get you on your way with this scenario!

Forwarding requests via a proxy

In package.json...

1. if you set your start script to "npm run production", it will build the React app and Express will serve the static bundle over port 3000.

2. if you set your start script to "npm run development", it will concurrently start the webpack dev server/watcher and the Express server. The latter will be listening on port 3001, but you don't need to change anything in your code because: proxies!

As it stands, the server listens for requests to /api; to get this working in development mode, we're using http-proxy-middleware in src/setupProxy.js to forward any incoming request to /api/whatever/endpoint/you/have over to the target, i.e., the Express server.

Live-reloading and watch.json

There's a watch.json file that specifies a couple of conditions to keep Webpack and Glitch from interfering with each others' file watchers:

1. We only want to run install scripts when changes are made to the package.json and .env files. Installation can take a while, so we don't want to trigger it with any other changes.
2. We only want to restart the project when changes are made in the /server folder, or to the watch.json file. We're including watch.json in case we need to kick off a restart — a change to the throttle value will trigger this. We're also explicitly ignoring any files in the /public and /src directories from kicking off a restart — we only want the Webpack watcher to handle these files.
3. We're setting a throttle of 100, which means that the Glitch watcher will wait 100 milliseconds before restarting anything. If that seems too quick, you can increase it.

Made with Glitch

Glitch is a collaborative programming environment that lives in your browser and deploys code as you type.

Use Glitch to build anything from a good ol’ static webpage to full-stack Node apps.
