@marginallyuseful/soll-turbopack

Turbopack integration for soll — scans production builds for chunk-to-source mappings.

Usage

CLI (CI pipelines)

next build
soll-turbopack .next/
npx playwright test

Programmatic

import { scanTurbopack } from "@marginallyuseful/soll-turbopack";

scanTurbopack({ buildDir: ".next" });

How it works

1. Walks the .next/ build output for JS files with sourcemaps
2. Parses each sourcemap's sources[] array
3. Strips turbopack:///[project]/ prefixes, filters framework/runtime/vendor entries
4. Writes chunk→source mappings to the soll bundler plugin store

The @marginallyuseful/soll-playwright fixture reads these mappings for test selection.

Requirements

Set productionBrowserSourceMaps: true in next.config for client-side sourcemaps. Server-side chunks always have sourcemaps regardless of this setting.
