#nextjs devs,

Since nextjs redirect can't be used inside `try/catch` block, How do you handle the redirections in server actions?

Especially when you don't want to handle `| undefined` in the return type of function in #TypeScript.

As of now I am doing redirection on client.

Is there a better way?

An SSR Performance Showdown

🔍 Comprehensive #SSR Performance Testing:
• Test setup: 2398 div elements spiral rendering on #NodeJS v22, #M1Mac with 8GB RAM

📊 Performance Rankings (requests/second):
• #fastifyhtml: 1088 (baseline templating)
• #Vue: 1028 (best full-featured performance)
• #Svelte5: 968 (pre-release version)
• #SolidJS: 907 (impacted by hydration IDs)
• #Preact: 717 (lightweight alternative)
• #React19: 572 (RC version)

🛠️ Testing Environment:
• Built using #Fastify and @fastify/vite
• Production builds tested
• Consistent styling and template implementations
• No client-side reactivity features

💡 Key Findings:
• #Vue and #Svelte offer best balance of performance and ecosystem maturity
• Hydration markers impact performance (demonstrated in #SolidJS)
• Simple templating (#fastifyhtml) outperforms full frameworks

Web devs keep introducing new frameworks and changes to make sure current ai never becomes capable of replacing them 😄

Excuse my language, but this is the first thing that came into my head when reading this - Fuck yes! - https://react.dev/blog/2024/04/25/react-19#ref-as-a-prop #react19

Hearing about all the changes in #React19 is giving me anxiety. I've been working on #React apps at my past four or five jobs now, but I just have no interest in relearning #ReactJS for the upteenth time, and I'm worried that is going to impact my ability to get another job if I ever decide to go back to work.
