微信小程序

小程序基础库: 和小程序版本无关
使用框架: React

复现步骤

操作步骤：任意一个hello word项目编译后，查看首页的源码及.map文件。

示例

taro源码（最简单的示例）：

import React from 'react'
import { View, Text } from '@tarojs/components'
import { useLoad } from '@tarojs/taro'
import './index.scss'
import { p } from './a';
export default class Index extends React.Component {
    componentDidMount() {
        this.jump(p);
    }
 
    jump(b) {
        const a = 1;
        let c = a   b;
        throw new Error('sec-error' c)
    }
 
    render() { return 'test'; }
}

其中sourcesContent对应的源码部分，可以看出明显不是taro源码：

import _createClass from \"/Users/qitmac001076/other/code/taro-demo/ts-ggg/node_modules/@babel/runtime/helpers/esm/createClass.js\";
import _callSuper from \"/Users/qitmac001076/other/code/taro-demo/ts-ggg/node_modules/@babel/runtime/helpers/esm/callSuper.js\";
import _inherits from \"/Users/qitmac001076/other/code/taro-demo/ts-ggg/node_modules/@babel/runtime/helpers/esm/inherits.js\";
import React from 'react';
import './index.scss';
import { p } from './a';
var Index = /*#__PURE__*/function (_React$Component) {
  function Index() {
    _classCallCheck(this, Index);
    return _callSuper(this, Index, arguments);
  }
  _inherits(Index, _React$Component);
  return _createClass(Index, [{
    key: \"componentDidMount\",
    value: function componentDidMount() {
      this.jump(p);
    }
  }, {
    key: \"jump\",
    value: function jump(b) {
      var a = 1;
      var c = a   b;
      throw new Error('sec-error'   c);
    }
  }, {
    key: \"render\",
    value: function render() {
      return 'test';
    }
  }]);
}(React.Component);
export { Index as default };

期望结果

期望sourcemap对应的是taro源码

实际结果

现在结果是对应编译后的产物
