I know that Epic React 2 and Epic Web are completely different courses. Given that I’m already on the verge of completing Epic React 1, I’m currently confused about how to proceed next. Should I go for Epic React 2 to solidify my React knowledge and learn about React 19? Or should I pivot towards Epic Web, which offers a broader, full-stack curriculum that could help me become a more well-rounded developer? I’d appreciate any guidance on which path might be more beneficial at this point in my learning journey. What should I learn next?…

In this recording, I talk about a recurring challenge I face when building proprietary solutions—constantly switching between frameworks like Next.js, React Router, and TanStack. I tend to shift tools when I hit roadblocks (like authentication issues), which makes it hard to commit and go deep with one tech stack. I’m reaching out to ask Kent for advice on how to stay focused and build with confidence without always second-guessing my choices. Stuck in Stack Switching: How Do You Commit to One?…

I’m transitioning from SPAs with REST APIs to SSR applications using React Router Framework. While I’ve used layout routes and tools like SWR/React Query for route protection in React Router DOM, I just found out that actions in React Router Framework are still vulnerable to unauthorized POST requests. I use JWT auth with tokens stored in cookies—do I need to verify the JWT in every action on each route, or is there a global solution like Fastify’s onRequest hook?

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? Make your test fail Should I write a test or fix a bug?

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? 𝕏 Post What are your thoughts about Qwik and hydration?…

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.
