What you need to know about Parcel 2

Bundling JavaScript files is a technique to enhance website performance by reducing server requests, achieved by combining multiple files into one, thus improving user experience. The introduction of module bundlers like Parcel has simplified this process, allowing developers to manage complex build requirements with minimal configuration. Parcel 2, the latest version, offers numerous enhancements, including automated differential bundling, an overhauled plugin system, and default tree shaking for optimized performance. Its Rust-based JavaScript compiler significantly improves build speed, while features like automatic code splitting and improved error diagnostics further enhance developer efficiency. Parcel 2 supports modern browsers by generating native ES modules, reducing bundle sizes and load times, and provides image optimization tools that maintain quality while decreasing file size. With its focus on usability and performance, Parcel 2 is suitable for projects ranging from small-scale applications to large, complex systems.
