禁用使用babel-preset-env进行的承诺转译吗? [英] Disable promise transpilation using babel-preset-env?

问题描述

我正在使用babel-preset-env(通天塔6)，我找不到如何禁用承诺"转译的方法.

I'm using babel-preset-env (Babel 6) and I can't find out how to disable the "promise" transpilation.

我尝试使用:

{
  "presets": [
    [
      "env",
      {
        "exclude": ["transform-async-to-generator", "es6.promise"]
      }
    ]
  ],
  "plugins": [
    "transform-object-rest-spread",
    "transform-class-properties",
    [
      "fast-async",
      {
        "spec": true,
        "compiler": { "promises": true, "generators": false }
      }
    ]
  ]
}

并且，尽管它不会引发任何错误(与通过无效选项时会发生的错误不同)，但它仍会将承诺转换为runtimeGenerator函数.

and, while it doesn't throws any errors (unlike it happens when an invalid option is passed), it still transpiles promises into runtimeGenerator functions.

我如何使babel-preset-env能够翻译所有内容但保留诺言?

How can I make so that babel-preset-env will transpile everything but preserve promises?

推荐答案

好吧，现在有了实际的.babelrc并提及fast-async，依此类推...像这样的.babelrc似乎足以使用而不是regenerator-runtime等.

Okay, now with the actual .babelrc and mention of fast-async and so on... A .babelrc like this seems to be enough to use fast-async instead of regenerator-runtime etc.

{
  "presets": [
    [
      "env",
      {
        "exclude": ["babel-plugin-transform-async-to-generator", "babel-plugin-transform-regenerator"]
      }
    ]
  ],
  "plugins": [
    [
      "fast-async",
      {
        "spec": true,
        "compiler": { "promises": true, "generators": false }
      }
    ]
  ]
}
