我们正在尝试在移动端（react-native）和网络端（create-react-app）使用相同的 React 组件。

多亏了react-native-web（下面的配置），到目前为止它运行得很好。

然而，我们在 react-native 项目中广泛使用的react-native-vector-icons不能与react-native-web一起编译。这意味着任何使用带有矢量图标的组件的组件也需要特定的 Web 版本。拥有特定于 Web 的组件版本会影响维护。

有没有一种已知的方法，无需弹出 create-react-app 配置，来处理web中的 react-native-vector-icons等 3rd 方？

import {createIconSetFromIcoMoon} from "react-native-vector-icons";

import Font from './Font.json';
export default createIconSetFromIcoMoon(UbeyaFont);

到目前为止我们已经想到的事情： 我们目前正在研究两个想法：

  • 基于环境的导入： 

    # Pseudo code:
# if mobile import this, otherwise import that.

    我们不确定这种动态导入是否可行

  • 注入到node_modules/react-scripts 的Webpack 配置。不优雅，但我们有一个 gulp 手表，我们可以确保配置始终存在。

任何想法或想法都会受到赞赏。

配置： 我们构建了一个新的私有 NPM 包，其中包含所有 React 组件，并且通过使用gulp watch将包复制到移动和 Web 项目，我们省去了在开发过程中不断发布 npm和yarning的麻烦（Webstorm 的唯一缺点索引过程）。

我们最终使用 gulp 脚本来覆盖 webpack。阶段是：

1）构建替换包

我们为每个React Native 3rd 方构建了一个 web 版本。对于react-native-vector-icons，结果非常简单：

    import React from 'react';

    export const Icon = (props) => <div className="material-icons" 
                                        style={{color:props.color}}>
        {props.name}
    </div>;


    export default Icon;

2）调整Webpack配置

使用 gulp 我们覆盖create-react-app webpack 配置：

 resolve: {
        modules: ...
        alias: {
            "babel-runtime": path.dirname(
                require.resolve("babel-runtime/package.json")
            ),
            "react-native": "@ourcompany/react-native-web",
            "react-native-vector-icons": "@ourcompany/react-native-vector-icons",
   ...

gulp 任务脚本：

gulp.task("copyWebpack", function() {
    return gulp
        .src(["package.json", "src/_webpack/*.js"])
        .pipe(
            gulp.dest(
                path.resolve(pathWeb + "/node_modules/react-scripts/config")
            )
        );
});

笔记：

  • 弹出 create-react-app 的配置更简洁，但这意味着您需要维护配置，我们更喜欢保留配置并在构建过程中覆盖它。
  • 你会注意到我们已经覆盖了 react-native-web 本身。在下一个可选步骤中了解更多信息。

3) 扩展 react-native-web (可选)

如果您正在使用react-native-web尚不支持的组件，您需要为它们构建包并扩展react-native-web以便您的 Web 版本可以工作。只需创建一个新包@yourcompany/react-native-web并生成一个index.js ，其中导入react-native-web中确实存在的组件并引用您构建的组件。请注意，当我们构建项目时，react-native-web没有 FlatList 或 SectionList，而现在（2018 年 10 月）它两者都有（Modal 仍然缺失 :-)）。
