Notes

Migrating to TypeScript, Pain points

  • Start with loose TypeScript rules
  • Iteratively and over time, rather than one giant PR

Should we use Next.js rather than create-react-app?

  • Excited about Remix
  • Next.js is pretty solid

Testing library

  • Usually don't test lower level of components that doesn't have much logic
  • More focus on integration test and e2e test
  • Doesn't worth aiming for 100% testing coverage
  • Code coverage < Use-case coverage

Career advise for beginners

  • Be a nice person
  • Communication

RTL(React testing library)

Integration test in general

  • rarely use snapshots as it contains many irrelevant information
  • "I don't write tests, I write proofs"

Communication advise

  • Sharing everything that I do

Functional Component vs Class Component

  • 64%: 100% functional component

Linter on your test

  • Yes, recommend that
  • Writing in TypeScript as well

Take aways

  • I need to (want to) learn TypeScript
  • I need to (want to) learn Testing
