@babel/plugin-proposal-destructuring-private

將私有解構 var { #y: y } = this 轉換為 var y = this.#y。

範例

JavaScript
class Foo {
  x;
  #y;
  equalsTo({ x, #y: y }) {
    return this.x === x && this.#y === y;
  }
}

將轉換為

JavaScript
class Foo {
  x;
  #y;
  equalsTo(_p) {
    var { x } = _p, y = _p.#y;
    return this.x === x && this.#y === y;
  }
}

外掛遵循這些編譯器假設

npm install --save-dev @babel/plugin-proposal-destructuring-private

yarn add --dev @babel/plugin-proposal-destructuring-private

pnpm add --save-dev @babel/plugin-proposal-destructuring-private

babel.config.json
{
  "plugins": ["@babel/plugin-proposal-destructuring-private"]
}

由於輸出程式碼包含私有欄位，如果您已經使用其他類別功能外掛（例如 `@babel/plugin-transform-class-properties），請務必將其放在其他外掛之前。

babel.config.json
{
  "plugins": [
    "@babel/plugin-proposal-destructuring-private",
    "@babel/plugin-transform-class-properties"
  ]
}

Shell

babel --plugins @babel/plugin-proposal-destructuring-private script.js

JavaScript
require("@babel/core").transformSync("code", {
  plugins: ["@babel/plugin-proposal-destructuring-private"],
});
