babel vs babel-core vs babel-runtime [英] babel vs babel-core vs babel-runtime

问题描述

我的节点webpack项目使用三个babel库.这些和如何使用有什么区别?

My node webpack project uses three babel libraries. What's the difference between these and how are they being used?

"dependencies": {
  "babel-runtime": "^5.8.24"
}

"dev-dependencies": {
  "babel": "^5.8.23",
  "babel-core": "^5.8.23"
}

推荐答案

babel-core是API.对于v5，babel程序包是CLI，并且取决于babel-core.对于v6，babel-cli程序包是CLI(尽管CLI bin命令仍然是babel)，而babel程序包不执行任何操作. babel-runtime我想这只是运行时(polyfill和助手)来支持已经转换的代码.

babel-core is the API. For v5 the babel package is the CLI and depends on babel-core. For v6, the babel-cli package is the CLI (the CLI bin command is still babel though) and the babel package doesn't do anything. babel-runtime I guess is just the runtime (polyfill and helpers) to support code that's already been transformed.
