@marginallyuseful/soll-vite

Vite plugin for soll — produces chunk-to-source mappings for browser test selection.

Usage

import soll from "@marginallyuseful/soll-vite";
import { defineConfig } from "vite";

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

The plugin hooks into Vite's build lifecycle to extract which source files are compiled into each output chunk. This data is written as a chunk overlay that the @marginallyuseful/soll-playwright fixture reads for test selection.

How it works

1. On build completion (writeBundle), the plugin iterates over all output chunks
2. For each chunk, it extracts the module list (source files) from Vite's module graph
3. All paths are normalized to git-root-relative format
4. The chunk overlay is written to .soll/chunk-overlay via the soll NAPI binding

No sourcemap parsing is needed — the plugin uses the module graph directly.
