Dev

Run target/node/npm test -- --coverage --watchAll to get unit tests constantly running. This has a mini console which can be used to re-run tests or to re-create jest snapshots

Run target/node/npm run --scripts-prepend-node-path to start up a server and open a browser w/ the UI constantly updating

I use pre-commit to run prettier and eslint as part of the pre-commit hook and checks

Tools

• prettier - format text
• eslint - find common bugs and such
• jest - testing framework. We use snapshots heavily
• testing-library - the tool to help test React w/ async, events and DOM changes etc
• nock - stub out REST calls
• We use React functional components and hooks instead of classes/objects
• We use a proxy which forwards a running nessie on port 19120 to the port where npm run runs the webserver (3000) avoids having to deal w/ xss
