Fight!

Popularity

Rollup is a more established and widely used bundler with a larger community and ecosystem. It has been around for longer and is often the go-to choice for many JavaScript developers. On the other hand, @parcel/core is a relatively newer bundler but has gained popularity due to its simplicity and zero-config approach.

Configuration

Rollup requires manual configuration through a configuration file, which gives developers more control and flexibility over the bundling process. @parcel/core, on the other hand, follows a zero-config approach, automatically detecting and bundling dependencies without the need for explicit configuration. This makes it easier and quicker to set up a project with @parcel/core.

Features

Rollup provides a rich set of features and supports advanced bundling techniques such as tree-shaking, code splitting, and dynamic imports. It also has a plugin ecosystem that allows developers to extend its functionality. @parcel/core focuses on simplicity and aims to provide a minimalistic and intuitive bundling experience. It supports common features like code splitting and caching but may not have the same level of advanced features as Rollup.

Performance

Rollup is known for its excellent performance and is optimized for creating small and efficient bundles. It achieves this through tree-shaking and other optimization techniques. @parcel/core also focuses on performance and aims to provide fast and efficient bundling. While both bundlers are performant, Rollup has a longer track record and is often considered the benchmark for bundler performance.

Developer Experience

Rollup has a mature and well-documented ecosystem with a large number of plugins and community support. It provides detailed error messages and has a wide range of configuration options, which can be overwhelming for beginners. @parcel/core, on the other hand, aims to provide a simpler and more beginner-friendly experience. It has a smaller plugin ecosystem but offers a streamlined and intuitive workflow.

Scalability

Rollup is a highly scalable bundler and is suitable for both small and large projects. It provides fine-grained control over the bundling process, making it easier to optimize and customize the output. @parcel/core is also scalable and can handle projects of various sizes. Its zero-config approach makes it particularly well-suited for small to medium-sized projects or for developers who prefer a more opinionated setup.
