Vue 3 over Vue 2

So, Vue.js 3, it’s got a lot of cool updates over Vue.js 2. First of all, it’s smaller. That’s right, the bundle size got trimmed down, which means faster downloads and quicker load times for your users. And who doesn’t love a fast app, right?

Now, performance

is a big deal too. Vue 3 took things up a notch here. Rendering? Yep, faster. Handling big lists? Vue 3 does it better. You’ll definitely notice things running smoother, especially with more complex apps.

But let’s talk about the Composition API

— this is huge. It’s a more flexible way of writing components, making your code cleaner and easier to maintain, especially in larger projects. You can organize logic better, and if you’re coming from React or like a function-based approach, this is gonna feel more natural. Don’t worry, the old Options API is still there, but the Composition API is a game-changer for some.

Oh, and if you love TypeScript,

Vue 3 has your back with better TypeScript support. No more jumping through hoops to get types working properly, and that’s pretty nice if you’re all about catching errors early.

Another improvement

is tree-shaking. Vue 3’s architecture allows it to get rid of unused code more effectively, meaning your final build only includes the stuff your app actually uses. That’s a win for performance and efficiency.

Also, the reactivity system got an overhaul. Vue 3’s reactivity is now more powerful and efficient. It’s easier to understand and manipulate reactive data, especially when working with complex states.

Finally,

there are plenty of other new features sprinkled in, like better async component support, a more modular runtime, and some cool improvements in how v-model works.

All in all, Vue.js 3 feels like a polished, more powerful version of Vue.js 2. It’s definitely worth the upgrade, especially for new projects, and it makes working with Vue even more enjoyable.
