What is the relationship between Rsbuild and Rspack?#

Rspack is the base bundler for Rsbuild. The goal of Rsbuild is to provide out-of-the-box building capabilities for Rspack users, allowing developers to start a web project with zero configuration.

The main differences between Rspack and Rsbuild are:

• Rspack projects need to be configured from scratch, while Rsbuild provides default best practice configurations and supports extending Rspack configurations.
• Rspack projects require integration with loaders and plugins from the community to support different scenarios, while Rsbuild provides official plugins and default support for common frontend frameworks and build capabilities.
• The capabilities of Rspack CLI are comparable to Webpack CLI, with relatively streamlined functionality, while Rsbuild provides a more powerful CLI and a more complete dev server.
