2 years ago You can create and use custom plugins with SWC.
Warning: Passing the AST to the JS Plugin system is a performance bottleneck.
Therefore, we are considering two approaches for the next SWC major version:
Creating a plugin system in Rust (#2337) Solve the bottleneck to keep a JS plugin system (#2175)
感觉他们也很纠结，rsut plugin 当然速度快性能高，但是 rust 本身门槛就很高。js plugin 必然效率比 rust plugin 要低很多，同时这种需要 rust 和 js 交互的性能损耗可能会高于纯 js 写（我理解 n-api 这种方式还是比较适合低频 + 简单的输入 + 简单的输出 + 大量的计算耗时）。不知道 swc 是只用 rust 做了 ast 部分还是也做了其他部分比如 plugin（理论上说应该不需要）
