What do you think about mutation testing applied to components? Feb 20, 2025

Show notes

I’d love to hear your thoughts on mutation testing when applied to components. In my experience, it doesn’t seem to make much sense because it often reports that tests still pass after altering aspects that aren’t relevant to the component’s behavior. To me, this type of testing seems more suited for pure unit tests. What’s your perspective on this?

When is a Promise not good enough, and I need a Web Worker? Jan 17, 2025

Show notes

I just finished Expensive Calculations in React Performance. Why do we need a Web Worker instead of just wrapping the long-running function in a Promise that resolves when the function completes?

What are your thoughts about Qwik and hydration? Jan 07, 2025

Show notes

What do you think about resumability and Qwik? About 9 months ago, there was talk about Wiz and Angular working more closely together (Wiz was the tool that inspired Qwik). But Angular only committed to working on partial hydration support, not the full resumability like Qwik. So do you think React developers should care about this? If so, should they use partial hydration tools like Astro today or wait for something like resumability to be added to React?

Dependent driven motivation and embracing AI Jan 06, 2025

Show notes

I would like to know how you get motivated knowing that you have dependents and stay strong in the event of layoff. How do you handle the fear of AI taking over job?

P.S. I didn't really mention much about AI so feel free to ask a follow-up on this for a more specific answer, but I would say that AI is just an important tool we need to learn and keep using the best tools to get the best benefits.

Does the testing trophy need updating for 2025? Dec 09, 2024

Show notes

In 2024, we live in a world where the defacto for creating React applications is SSR (e.g. Remix, react router v7, Next, TanStack). Coupled with the rise in performance, reliability and reduction of cost in running e2e tests by playwright and now vitest's Browser Mode, is it time to consider reworking the Testing Trophy to make e2e tests the largest proportion of the trophy?

This is starting to make more and more sense to me as e2e tests are becoming as cheap to execute as integration tests, whilst integration tests are more complex to write in a SSR application without mocking client side or server side code.

Balancing Conventions and Flexibility in Large Codebases Dec 06, 2024

Show notes

I’m curious about your thoughts on balancing conventions in large codebases. For context, I’m working in a project with ~20 developers across four separate teams. Where do you think we should draw the line between enforcing conventions for consistency and leaving room for flexibility in individual contributions?
