Vize

[!WARNING] Vize is experimental and in its Real World Testing phase — not a completely production-ready toolchain yet. Breaking changes and behavior that diverges from Vue are expected. Review the stability guide, production-readiness checklist, and support policy before adopting it.

What Is Vize?

Vize is a Rust-native toolchain for Vue. One shared parser powers compilation, linting, type-checking, formatting, and editor tooling, so the Vue workflow runs on the same core instead of a patchwork of disconnected tools.

It plugs into the tools you already use: @vizejs/vite-plugin for Vite, @vizejs/nuxt for Nuxt, the vize package for project scripts, oxlint-plugin-vize for Oxlint, and @vizejs/vite-plugin-musea for the component gallery.

Usage

Vize is a toolchain you add to a Vue app. It does not scaffold the app itself. Pick the shortest path that matches your project; the docs have the rest.

Drop-in

On a Vue 3 + Vite app, replace @vitejs/plugin-vue with @vizejs/vite-plugin. Your SFCs stay as they are.

npm i -D @vizejs/vite-plugin

// vite.config.ts
import { defineConfig } from "vite";
import vize from "@vizejs/vite-plugin";

export default defineConfig({
  plugins: [vize()],
});

Then use the same dev / build scripts as before. This swaps SFC compilation only. Lint, format, and type-check stay on your current tools until you add them. The claim is Vue 3 SFCs in Vite — see Drop-in Scope.

Nuxt apps should use @vizejs/nuxt instead of wiring the Vite plugin by hand.

Type checking

Type-check .vue files with TypeScript 7.1 or newer and Vize's content mapper. tsrs can run the same tsconfig.

npm i -D vize typescript@beta

{
  "contentMappers": [{ "package": "vize", "extensions": [".vue"] }]
}

npx tsc --runExternalCode --noEmit -p tsconfig.json
npx tsrs --runExternalCode --noEmit -p tsconfig.json

typescript@beta is the 7.1 beta, the first release that includes content mappers. After 7.1 is stable, install typescript at 7.1 or newer and keep the same command. Details are in the type checking guide.

New setup

Create a Vue + Vite or Nuxt app first, then let vize init wire the toolchain.

Vue + Vite:

npm create vue@latest my-app
cd my-app
npx vize init

Nuxt:

npm create nuxt@latest my-app
cd my-app
npx vize init

init can add the Vite plugin or Nuxt module, Oxlint, vize fmt, vize check, and a VS Code recommendation. If you already have Vite+, run vpx vize init instead.

Migration

For an existing Vite, Vite+, or Nuxt project, preview the plan, then apply it:

npx vize init --dry-run
npx vize init

init is idempotent and lets you choose surfaces. Existing vize.config.* is left as-is. A second run adds no duplicate plugin, script, or dependency. The first run may still add vize:* scripts and update a plain vite.config.* or nuxt.config.*.

Non-interactive:

npx vize init --yes --lint --bundler --fmt --typecheck --editor

If you only want the compiler, use the drop-in swap above. Custom vue({ ... }) options and unusual Vite configs are not rewritten automatically. See Project Setup.

Vize is in its Real World Testing phase: fix requests and PRs are very welcome, and we are looking for reasonably large Vue projects to use as test beds.

Type-check ratios compare Vize with vue-tsc, the type checker Vue projects run today. vue-tsc drives the JavaScript TypeScript compiler while Vize drives native tsgo, so the ratio covers the whole toolchain rather than the Vue layer alone; the per-engine-class tables in the full snapshot rank same-engine tools against each other to isolate that layer. Each timed invocation passes diagnostic-work validation. Diagnostic coverage differs between tools; these ratios do not prove accuracy parity or a performance improvement over an earlier Vize version. Rejected comparators have no published timing or rank.

Nuxt measures the entire build pipeline, not isolated SFC compilation. Most build work is shared by both variants. Its ratio is 0.95x; a ratio below 1 means Vize was slower in this run.

See the Blacksmith benchmark snapshot for per-variant timings, diagnostic counts, rejected measurements and methodology.
