 bundleless, on the other hand, means that each source file is compiled and built separately, but not bundled together. Each output file can be found with its corresponding source code file. The process of bundleless build can also be understood as the process of code conversion of source files only.

 They have their own benefits.
 
-- bundle can reduce the size of build artifacts and also pre-package dependencies to reduce the size of installed dependencies. Packaging libraries in advance can speed up application project builds.

 - bundleless maintains the original file structure and is more conducive to debugging and tree shaking.

 而 bundleless，则是指对每个源文件单独进行编译构建，但是并不将它们打包在一起。每一个产物文件都可以找到与之相对应的源码文件。bundleless 构建的过程，也可以理解为仅对源文件进行代码转换的过程。

 它们有各自的好处：
 
-- bundle 可以减少构建产物的体积，也可以对依赖预打包，减小安装依赖的体积。提前对库进行打包，可以加快应用项目构建的速度。
