Rollup integration

// rollup.config.js
import { tracelessStyle } from "traceless-style/rollup";

export default {
  input: "src/index.ts",
  output: { dir: "dist", format: "esm" },
  plugins: [tracelessStyle()],
};

Options

tracelessStyle({
  srcDir: "src",
  dev:    false,
});

Hooks used

• buildStart — full extraction (Pass 0/1/2).
• transform — per-file tl.create rewrites.

CSS output lands in public/traceless-style.css.

Importing the CSS

The Rollup plugin does not auto-inject the stylesheet. Add an import:

// src/index.ts
import "../public/traceless-style.css";

…or use a CSS-handling Rollup plugin (e.g. @rollup/plugin-postcss) that picks it up.

When to use Rollup vs Vite

Vite uses Rollup under the hood, so the Vite plugin already covers most use cases. Use the raw Rollup plugin when:

• You're building a library and need fine-grained Rollup control.
• You're using Rollup directly (no Vite dev-server layer).
• You need the plugin in a tool that wraps Rollup (e.g. Astro's component island bundler).
