v0.6.0

Per-Module ESM Dev Server with HMR

The dev server now serves individual ESM modules instead of opaque compiled
files. Each .ts, .vue, .jsx file gets its own URL, and import specifiers
are rewritten so the browser resolves the full module graph natively:

• Relative imports (./utils) → /assets/utils.ts
• Bare imports (vue) → /@vendor/vue.js (pre-bundled)
• Alias imports (@/utils) → resolved via tsconfig paths or config aliases

Each JS module is injected with an import.meta.hot preamble for granular HMR:

if (import.meta.hot) {
  import.meta.hot.dispose(() => clearInterval(timer));
  import.meta.hot.accept();
}

On file change, the watcher walks the dependency graph upward to find the
nearest import.meta.hot.accept() boundary. Only that module is re-imported
via import("/@assets/Button.tsx?t=123") — no full page reload. Accept
callbacks receive the new module exports. Falls back to location.reload()
when no boundary is found.

TypeScript assets (HMR client, console forwarder, error overlay) are now
compiled to JS via OXC before serving to the browser.

Production Source Maps

Source maps are now fully usable in production builds:

• sourcemap: true — write .map files and append //# sourceMappingURL (default)
• sourcemap: :hidden — write .map files without the URL comment (for Sentry, Datadog)
• sourcemap: false — no source maps
• Chunked builds now generate source maps (previously discarded)
• CLI: --sourcemap hidden

tsconfig.json Paths

Volt automatically reads compilerOptions.paths from tsconfig.json in the
project root and merges them into aliases. Explicit aliases take precedence.
Supports baseUrl for path resolution.

Manual Chunk Splitting

Control chunk boundaries via config:

config :volt,
  chunks: %{
    "vendor" => ["vue", "vue-router", "pinia"],
    "ui" => ["assets/src/components"]
  }

Bare specifiers match package names in node_modules. Path patterns match by
directory prefix. Manual chunks work alongside automatic dynamic-import splitting.

Bug Fixes

• Fix alias-imported Vue SFCs silently dropping bare npm imports from the bundle

Internal

• Reorganize internal modules into Volt.JS.*, Volt.CSS.*, Volt.Dev.* namespaces
• Add Playwright browser integration tests (mix test --include integration)
