What’s New in Vue 3.5 – A Quick Guide for Developers

Vue.js continues to evolve — and the release of Vue 3.5 proves that Evan You and the core team are serious about performance, DX, and modern app architecture.

Whether you're just getting started or maintaining large-scale apps, Vue 3.5 introduces updates that can impact your workflow, speed, and app structure.

Let’s walk through the most important highlights.


🔥 1. <script setup> Enhancements

Vue 3.5 improves ergonomics around <script setup> — now the preferred way of writing components.

What’s new:

  • DefineProps auto type inference: No need to manually type props if using TS.

  • defineModel() Improvements: More flexible support for two-way bindings.

vue
<script setup lang="ts"> const modelValue = defineModel<string>() </script>

This makes building form components and reusable inputs far cleaner.


⚙️ 2. Server-Side Rendering (SSR) Optimizations

Vue 3.5 enhances SSR performance, reducing render time and bundle size.
If you're using Nuxt 3 or building SSR apps manually, you’ll see performance gains right away.


🧩 3. Custom Directive Improvements

Now you can use argument and modifier inference for custom directives in TypeScript. That’s huge for building things like tooltips, drag-and-drop, or gesture-based components.

ts
interface VTooltipBinding { value: string modifiers: { top: boolean } arg?: string }

🧪 4. Compiler Updates

Vue’s compiler now outputs more optimized code during build time — which means:

  • Smaller production builds

  • Smarter handling of slots and conditionals

  • Better support for devtools debugging


🧰 5. Tooling Upgrades

  • Official Vue language tools for VSCode have been updated.

  • Volar 2 now supports more granular type inference in <script setup> files.

  • Improved DX when working with Vite, especially in monorepos.


🧠 Should You Upgrade?

If you're already on Vue 3, upgrading to 3.5 is non-breaking and highly recommended.
If you're on Vue 2 — it's seriously time to consider migrating (and now’s the best moment).


🚀 Building With Vue 3.5

At ICreator Studio, we’ve already started integrating Vue 3.5 features into our latest admin templates — especially the <script setup> enhancements and improved DX tooling.

Whether you're building dashboards, SaaS apps, or internal tools, Vue 3.5 gives you the flexibility and power to move faster — with cleaner code.


🏁 Final Thoughts

Vue 3.5 is a major leap forward in developer experience without breaking existing apps. If you haven’t explored it yet, now’s the perfect time to upgrade and simplify your codebase.
