TanStack AI is now in Beta!

TanStack AI is no longer just a text-generation library with extras bolted on. TanStack AI has first-class dev experience for:

✅ Text and Streaming Structured Data
✅ Tool Calls
✅ Summarization
✅ Image Generation
✅ Video Generation
✅ Audio Generation
✅ Realtime voice chat
✅ Middleware
✅ Lazy tool discovery
✅ Code Mode
✅ Host-side MCP
✅ Orchestration (still experimental)
✅ Pluggable debug logging
✅ Isomorphic devtools

All with per-model type-safety that actually matters!

It’s been quite a while since I last wrote a blog post! https://t.co/3JaRH1OsTS

/improve-codebase-architecture will soon output HTML

This rocks, thanks @trq212

FINALLY! I've been saying this for a while.

Most apps would be just fine using React, Vite and TanStack Router/React Router.

Sadly, people love to overcomplicate things.

Boris Cherny, the creator of Claude Code at Anthropic, just listed 9 patterns that waste 73% of your tokens.

in this podcast he breaks down exactly how the model burns tokens before it even reads your prompt:

- the 14% you lose to CLAUDE.md before typing a word
- the 13% you pay re-reading old chat history
- the 11% from hooks you forgot you installed
- why most "Claude got dumber" complaints are wrong

if you're hitting Max limits more than once a week, you have at least 4 of these. Probably 7.

instead of another show tonight, watch this.

my own breakdown based on 400+ hours of usage is below, read it after the podcast

We've re-built Conductor from scratch to make it twice as fast.

Creating tabs, switching workspaces, and rendering files are all 50% faster, memory usage is lower, and the app is 150 MB smaller.

Introducing Conductor Allegro!

Zustand is officially more popular than Redux

❌ Don't use barrel imports in React
✅ Import components directly

Barrel imports (index.js re-exports) import the entire module even if you need one component.

This adds unused code to your bundle ↓

Oxfmt now supports Tailwind CSS class sorting!

ECMAScript excitement 😉

Congrats to @ManishEarth on unflagging @TC39 Stage 3 Temporal in V8 today. Heading for Chrome 144 🎉

By many metrics this new date/time API is the single biggest change to JS ever 🔥

It uses Boa's temporal_rs by @Jason_williams Kevin Ness & Manish 👍

This is coming from the guy who made jQuery.

If I got a compliment like this I would either faint or immediately retire. Highest honor in JS imo

[Charlie Lamb @charlietlamb]

the reason @shadcn is used in so many apps isn't that the components look good. it's the composition pattern.

the composition pattern is by far the best way to write frontend code - @fernandorojo gives a brilliant talk about it

[Fernando Rojo @fernandorojo]

Composition is all you need.

[Jarred Sumner @jarredsumner]

In the next version of Bun

`bun update --interactive` helps you select which dependencies to update.

Interesting read! https://t.co/q3JKhR6Bmz
- Every abstraction adds cognitive load.
- Duplication is better than the wrong abstraction.
- Locality matters, related code should live near each other.

Five minutes before standup…

The TS Go port now has a VSCode extension you can try.

Instant autocomplete, even on 1.5m LOC projects
