Modern JavaScript Bundling with Rollup: Definitive Reference for Developers and Engineers

"Modern JavaScript Bundling with Rollup"

"Modern JavaScript Bundling with Rollup" is a comprehensive and expertly crafted guide designed for developers and architects aiming to master efficient and scalable JavaScript application delivery. The book begins by tracing the evolution of JavaScript bundling, offering a penetrating look at modular JavaScript’s origins, a comparative analysis of module formats such as CommonJS and ES Modules, and the motivations that have shaped today’s complex bundling landscape. With a critical survey of leading bundlers—such as Rollup, Webpack, Parcel, and esbuild—the early chapters equip readers to navigate the modern application ecosystem, from single-page applications to micro-frontends.

Diving deep into the architecture and inner workings of Rollup, the book provides authoritative coverage on configuration techniques, plugin systems, and advanced extension patterns. Readers will benefit from detailed explorations of input/output options, plugin development, module resolution, code splitting, and tree shaking—accompanied by practical strategies for managing large-scale builds, performance optimizations, and bundle analysis. Real-world case studies illuminate how advanced configurations, custom plugins, and integration with tools like Babel and TypeScript can be harnessed to solve complex architectural challenges.

Beyond code, "Modern JavaScript Bundling with Rollup" addresses the broader developmental concerns crucial for long-term project success: seamless integration of non-JavaScript assets, universal application patterns, supply chain security, compliance, and ongoing maintainability. The book closes with a forward-looking perspective on emerging patterns, such as native ESM support, micro-bundling, edge computing, and the future trajectory of JavaScript tooling. Expertly structured and rich in technical depth, this work stands as an indispensable reference for any team or individual intent on professional-grade JavaScript delivery.
