我有一个React应用，其中有许多导入相同模块的组件。webpack是否为每个请求它的文件导入每个模块一次，从而导致重复的代码（在这种情况下，每个模块仅对两个组件导入两次）？我正在考虑重新编写组件，以便子组件不需要使用React模块，但是也许我正在解决一个不存在的问题。我想避免同一反应模块的多次导入，如果它导致重复的代码。

组件1

import React from "react";
import { Link } from "react-router";
import ReactLogo from "elements/ReactLogo";

export default class MainMenu extends React.Component {
    render() {
        return <div>
            <ReactLogo type="svg" /> <ReactLogo type="png" /> <ReactLogo type="jpg" />
            <h2>MainMenu:</h2>
            <ul>
                <li>The <Link to="home">home</Link> page.</li>
                <li>Do something on the <Link to="todo">todo page</Link>.</li>
                <li>Switch to <Link to="some-page">some page</Link>.</li>
                <li>Open the chat demo: <Link to="chat" params={{room: "home"}}>Chat</Link>.</li>
                <li>Open the page that shows <Link to="readme">README.md</Link>.</li>
            </ul>
        </div>;
    }
}

组件2导入相同的3个模块。

import React from "react";
import { Link } from "react-router";
import ReactLogo from "elements/ReactLogo";

export default class MainMenu extends React.Component {
    render() {
        return <div>
            <ReactLogo type="svg" /> <ReactLogo type="png" /> <ReactLogo type="jpg" />
            <h2>MainMenu:</h2>
            <ul>
                <li>The <Link to="home">home</Link> page.</li>
                <li>Do something on the <Link to="todo">todo page</Link>.</li>
                <li>Switch to <Link to="some-page">some page</Link>.</li>
                <li>Open the chat demo: <Link to="chat" params={{room: "home"}}>Chat</Link>.</li>
                <li>Open the page that shows <Link to="readme">README.md</Link>.</li>
            </ul>
        </div>;
    }
}
