The State of JS 2025 results are out!

🏆 Most Adopted Tech → Vitest
🏆 Highest Satisfaction → Vite (98%) & Vitest (97%)
🏆 Highest Interest → Vitest (83%) & Rolldown (80%)

But that's not all!

A thread 🧵

Tuist now includes links to the PRs in every changelog entry so you can see the code that enabled each feature or fix 🔗

Better transparency and easier to dive into the implementation details when you need them.

found this metal-punch plate for encoding x/y coordinates on a telephone pole in columbus ohio. probably in a local grid system?

Enabling it is simple. Just add this to your Rolldown config:

```js
export default {
  experimental: {
    lazyBarrel: true,
  },
};
```

For Vite 8, you can put it under `build.rolldownOptions`

Rolldown's Lazy Barrel Optimization supports all the patterns you'd expect:

◆ `export * from './components'`
◆ `export { Component } from './Component'`
◆ `export * as ns from './module'`
◆ Mixed exports
◆ Circular references
◆ Self re-exports

Real-world impact with Ant Design as example

```js
import { Button } from 'antd';
```

◆ Without: 2986 modules, ~65ms
◆ With: 250 modules, ~28ms

That's 92% fewer modules and 2-4x faster builds.

Without any optimization, your bundler has to traverse the entire barrel file and compile all modules, even the unused ones.
But with Lazy Barrel Optimization, Rolldown only includes what you actually use and skips the rest.

You often do not use all functions or components from a library, but they are all exported from a single barrel file.

```js
// some-lib/index.js
export { a } from './a';
export { b } from './b';
// more exports here [...]

// main.js
import { a } from 'some-lib';
```

🚀 Lazy Barrel Optimization in Rolldown

Barrel files, files that re-export from other modules, are common in modern JavaScript projects but a nightmare for your build time.
Rolldown now has Lazy Barrel Optimization to fix this.

Here's how it works 🧵

database correctness seems like the only kind, database software is all formally proven and simulation tested and every other genre of software is the wild west. "actually testing web applications" is impossible in practice. i feel like this engenders an unearned sense of superiority.

Hey! Good catch! We had a temporary 404 on that deploy button SVG, but it should be back now. If you're still seeing it on your end, try a hard refresh and let us know what browser you're on.

More than 3,000 databases created in 30 days using "npx create-db"!

Always humbling. Thanks for trying it 🫶

This is such a cool use of activity data! Love the clustering + city overlay idea...and the stack is chef’s kiss. Thanks for building on Netlify 🫶

👋 we can build more IaC features! We could even become terraform provider, I think

Sounds like what we do! Let's chat :)
