Bob The Bundler

Bob The Bundler is a TypeScript build and bundle tool designed primarily for monorepos, widely used by The Guild's open-source projects. Its current stable version is 7.0.1, with major releases introducing breaking changes, often around module systems and Node.js compatibility. Key features include building ESM and CommonJS compatible npm packages, verifying module imports for usability, and enabling incremental builds for performance in monorepo setups. It supports pnpm workspaces and offers configurable TypeScript `tsconfig` paths. Bob emphasizes a strict, convention-based approach to bundling, providing a robust solution for complex JavaScript/TypeScript projects that require precise control over build outputs and types.
