browserslist设置无效

[chenyulun]

father-build@1.21.1

然后再package.json里面配置

  "browserslist": [
    "chrome >= 90",
    "ios >= 15",
    "not IE 11"
  ]

然后代码里面写

const abc = async (params:string) => {
   console.log(params)
 }
 abc('111')

还是被降级了

import React from 'react';

/**
 * title: Foo demo
 * thumbnail: http://localhost:8080/#/calendar
 * previewUrl: http://localhost:8080/#/calendar
 */

var Foo = function Foo(_ref2) {
  var _ref2$title = _ref2.title,
      title = _ref2$title === void 0 ? '你好' : _ref2$title;
  return /*#__PURE__*/React.createElement("h1", null, title);
};

function asyncGeneratorStep(gen, resolve, reject, _next, _throw, key, arg) {
  try {
    var info = gen[key](arg);
    var value = info.value;
  } catch (error) {
    reject(error);
    return;
  }

  if (info.done) {
    resolve(value);
  } else {
    Promise.resolve(value).then(_next, _throw);
  }
}

function _asyncToGenerator(fn) {
  return function () {
    var self = this,
        args = arguments;
    return new Promise(function (resolve, reject) {
      var gen = fn.apply(self, args);

      function _next(value) {
        asyncGeneratorStep(gen, resolve, reject, _next, _throw, "next", value);
      }

      function _throw(err) {
        asyncGeneratorStep(gen, resolve, reject, _next, _throw, "throw", err);
      }

      _next(undefined);
    });
  };
}

var Button = function Button(_ref) {
  var _ref$type = _ref.type,
      type = _ref$type === void 0 ? 'primary' : _ref$type,
      _ref$children = _ref.children,
      children = _ref$children === void 0 ? null : _ref$children;

  var abc = /*#__PURE__*/function () {
    var _ref2 = _asyncToGenerator( /*#__PURE__*/regeneratorRuntime.mark(function _callee(params) {
      return regeneratorRuntime.wrap(function _callee$(_context) {
        while (1) {
          switch (_context.prev = _context.next) {
            case 0:
              console.log(params);

            case 1:
            case "end":
              return _context.stop();
          }
        }
      }, _callee);
    }));

    return function abc(_x) {
      return _ref2.apply(this, arguments);
    };
  }();

  abc('111');
  return /*#__PURE__*/React.createElement("button", {
    type: "button",
    className: type
  }, children);
};

export { Button, Foo };

建议修改node_modules/father-build/src/getBabelConfig.ts配置,
建议1：去除写死配置babel会自动使用browserslist去查找当前执行目录的配置，不需要您这边写死
建议2：增加配置项，

  return {
    opts: {
      presets: [
        ...(typescript ? [require.resolve('@babel/preset-typescript')] : []),
        [require.resolve('@babel/preset-env'), {
-         targets,
          modules: type === 'esm' ? false : 'auto'
        }],
        ...(isBrowser ? [require.resolve('@babel/preset-react')] : []),
      ],

去掉就可以构建了

import React from 'react';

/**
 * title: Foo demo
 * thumbnail: http://localhost:8080/#/calendar
 * previewUrl: http://localhost:8080/#/calendar
 */

const Foo = _ref2 => {
  let {
    title = '你好'
  } = _ref2;
  return /*#__PURE__*/React.createElement("h1", null, title);
};

const Button = _ref => {
  let {
    type = 'primary',
    children = null
  } = _ref;

  const abc = async params => {
    console.log(params);
  };

  abc('111');
  return /*#__PURE__*/React.createElement("button", {
    type: "button",
    className: type
  }, children);
};

export { Button, Foo };

目前 targets 不支持自定义，正在做 father 的下个大版本，新版会支持

目前 targets 不支持自定义，正在做 father 的下个大版本，新版会支持

所以现在 4.0 了，怎么自定义呢，文档上没有看到

[PeachScript]

暂时还不支持

感谢 @huarse 的 PR #549 ，targets 配置项已在 father 4 中支持：https://github.com/umijs/father/blob/master/docs/config.md#targets
