Tokamak

Tokamak is an isomorphic self-bundling bundler (version 0.0.15) aimed at Node.js and browser environments. It converts all modules to CommonJS (CJS) format, deliberately deviating from the ESM trend. Key differentiators include support for CJS-only npm modules and easier automatic HMR isolation. Drawbacks include lack of ESM circular dependency support and export-by-value semantics (e.g., `export let` modifications are not propagated). The bundler runs a static analysis to build a require graph, then generates a dynamic require function for the browser. Actively maintained with irregular releases.
