🍿 How TanStack Makes Server Functions Ridiculously Simple

I just got back from Amsterdam after speaking at React Summit and wow, what a week! 🇳🇱

I gave a talk called React Framework Showdown 🥊, where I pitted Next.js, TanStack Start, and React Router v7 (aka Remix) against each other in a friendly battle.

Why those three? Because they're leading the pack when it comes to modern React and honestly, each one brought something wildly different to the table.

I'll share the talk when it's live, but for now, let’s hear it from this week's sponsor👇

PRESENTED BY MENTORCRUISE

I know how frustrating self-learning can get, endless tabs open, jumping between blogs, and still feeling stuck.

That’s why I love what MentorCruise is doing.

Instead of one-off coffee chats or random advice, they connect you with vetted mentors (less than 5% get accepted!) who actually meet with you regularly. Whether you're trying to land a new role, get promoted, or level up a skill, you get consistent support, a custom plan, and real accountability.

It’s way more affordable than bootcamps and way more effective than going at it alone. Most folks hit major milestones in just 3 months.

If you’re serious about growing faster, check them out. MentorCruise is built for outcomes, not guesswork.

TanStack Server Functions work just like API routes but with superpowers: portable, framework-agnostic, and come with built-in validation.

Here’s what makes them unique:

🧪 Validation-first: Input gets validated before your function runs
​🔐 Auto-exposed: They become public HTTP endpoints without fixed URLs

✅ Step 1: Validates the input using Zod
​🧠 Step 2: If validation passes, your handler runs
​🌐 Step 3: This function becomes an HTTP endpoint you can call from anywhere No need to set up API routes manually.
​
Just write a function and it's ready to use.

Dan Abramov’s back with a brain-bending post: Suppressions of Suppressions. It’s all about what happens when you over-suppress React warnings and how lint rules can help save you from yourself.

Still confused about 'use client' and how things import across Server Components? How Imports Work in RSC clears it up beautifully.

Feeling lost in React’s recent direction? Mark Erikson breaks it down with rare clarity, real reasons, community insights, and what the future looks like.

Want that soft, frosted look in your UI? Create a blurry glass effect with this quick CSS trick (video) — no frameworks, just clean styles.

TkDodo explains why TanStack Router is winning dev hearts with type safety, nested layouts, and smart preloading.

Need to store massive files for your app? Vercel Blob now supports uploads up to 5TB with retry support and streaming.

And if you’re building AI tools, Kibo UI’s AI Suggestion component gives you a clean, horizontal suggestion bar ready to drop into any app.
