Generate JavaScript README files, API docs, and module guides automatically. Codec8 handles CommonJS, ESM, and everything in between.
JavaScript projects often have no strict type information to anchor documentation on. You end up with a README that was accurate six months ago and an API that only you understand.
Tailored documentation features for JavaScript codebases
Extracts JSDoc comments and infers argument types from usage patterns
Documents both CommonJS (require) and ESM (import/export) module shapes
Generates npm install commands, scripts table, and peer dependency warnings
Produces callback vs Promise vs async/await usage examples from your actual code
From zero to published docs in under a minute

Codec8 reads your JavaScript source code, dependencies, and structure, then generates README, API docs, architecture diagrams, and setup guide.
