browser-pack-flat

Browserify plugin that bundles modules into a single scope, similar to Rollup, eliminating the require runtime wrapper. Current stable version is 3.5.0. Maintained sporadically; no major release since 2020. Differentiator: drastically reduces bundle size and execution overhead by rewriting require() calls to variable references and flattening module scopes. Unlike default browser-pack, it removes the per-module function wrapper and runtime, at the cost of potential execution order differences and incompatibility with certain patterns (e.g., wrapped require, factor-bundle). Supports an ecmaVersion option and IIFE removal via iife:false.
