Elixir bindings for Vize, a Vue.js toolchain written in Rust. Parse, analyze, lint, and compile Vue single-file components from Elixir, including Vapor mode and its intermediate representation, plus a LightningCSS-based CSS pipeline.

{:ok, result} =
  Vize.compile_sfc("""
  <template><button @click="count++">{{ count }}</button></template>
  <script setup>
  import { ref } from "vue"
  const count = ref(0)
  </script>
  <style scoped>button { color: blue }</style>
  """, filename: "Counter.vue")

result.code  # JavaScript module
result.css   # scoped CSS

def deps do
  [{:vize, "~> 0.17"}]
end

Precompiled NIFs are downloaded for macOS, Linux (glibc and musl), and Windows, so no Rust toolchain is needed. To build from source, set VIZE_EX_BUILD=1 and install Rust 1.95 or later.

• SFCs: parse descriptors with block locations, compile to DOM, Vapor, or SSR JavaScript with scoped CSS and content hashes, generate .d.ts declarations, and collect template assets and scope IDs for bundlers. See Single-file components.
• Analysis and linting: bindings, props, emits, component usages, and template expressions from Vize's semantic analysis, plus lint diagnostics. See Analysis and linting.
• Vapor mode: compile to Vapor JavaScript, or get the Vapor IR as Elixir maps for rendering on the BEAM. See Vapor mode.
• Templates and SSR: compile standalone templates to render functions, or to SSR code that _push()es HTML. See Templates and SSR.
• CSS: compile, scope, minify, autoprefix, and bundle CSS with LightningCSS, compile Sass and SCSS, and rewrite or transform stylesheets through a parser-backed AST. See CSS.

Volt uses Vize to build Vue apps, and PhoenixVapor uses it to render Vue templates as LiveView.

Guides, a cheatsheet, and the API reference are on HexDocs.

vize compiles and analyzes Vue single-file components from Elixir, including Vapor-mode IR for BEAM-native rendering.

It is part of a frontend stack that runs inside the BEAM — builds, JS runtimes, icons, and Vue-to-LiveView compilation as supervised parts of the application instead of external toolchain processes. See the Elixir Volt organization for the rest, and Building Blocks for the Future Web for the thesis, architecture, and roadmap that tie them together.
