Jiahan Chen(@jiahan_c):I used to dislike webpack’s loader design, but over time I’ve come to appreciate just how much it gets right: • Easy to parallelize: Loaders are standalone modules, so they can run in workers with little effort. I saw Rspack’s parallel loader feature cut babel-loader time by 80% in one large project • Composable: Loaders can be combined and ordered as needed to build flexible transformation pipelines • Cacheable: Loaders are usually stateless, making their results easy to cache and reuse • Portable: The same loader can run on webpack, Turbopack, and Rspack
