scratch-webpack-configuration

Shared webpack configuration builder for Scratch projects, version 3.1.2 as of March 2026. Provides a fluent API to construct webpack 5 configurations with defaults for Scratch's build pipeline, including Babel (with optional React), CSS (postcss-loader, css-loader, style-loader), TypeScript (ts-loader), asset modules via resource queries, chunk splitting, and target-specific externals for browserslist and Node. Released under BSD-3-Clause (was AGPL-3.0 in v2). Differentiators: opinionated but extensible via clone/merge, handles Scratch-specific module rules and externals, and integrates with Scratch's semantic release config. Requires webpack 5 and peer dependencies like @babel/preset-env, babel-loader, css-loader, postcss-loader, etc.
