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)

• RTL Everywhere
• Testing code is just an another code

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
