将react-native-web应用嵌入到现有网站中

问题描述

我想将react-native-web应用程序嵌入到现有网站中,目前正在寻找实现此目的的选项。

该应用程序应该是一个非常简单的调查表,需要将其嵌入到由Elementor创建的网站中。我的想法是使用Elementor HTML widget并以某种方式插入我的应用程序,但不幸的是我无法弄清楚该怎么做。

我在开发React Native(RN)应用方面有一些经验,但是我对Web开发非常陌生,因此我认为使用RN和react-native-web库会更容易。

到目前为止,我已经使用npx react-native init WebApp创建了一个RN项目,复制了 App.js index.js package.json来自react-native-web CodeSandbox template文件删除 node_modules 文件夹,然后运行npm install。然后,我能够使用 package.json 中的脚本启动并构建此示例Web应用程序。

现在我的问题是,如何使用 build 目录中的输出并将其嵌入到html标记中?

我还尝试将webpackreact-native-web docs的配置结合使用,以捆绑该应用程序,但在修复最后一个错误后,我总是会遇到新的错误。是否可以将RN应用程序捆绑到一个JS文件中,然后将其插入网站?

期待任何建议!

解决方法

我通过使用以下webpack配置解决了该问题。创建的bundle.web.js的内容被放入脚本标签(<script>...</script>)中。可以将其嵌入到HTML小部件中。

// web/webpack.config.js

const path = require('path');
const webpack = require('webpack');

const appDirectory = path.resolve(__dirname,'');

// This is needed for webpack to compile JavaScript.
// Many OSS React Native packages are not compiled to ES5 before being
// published. If you depend on uncompiled packages they may cause webpack build
// errors. To fix this webpack can be configured to compile to the necessary
// `node_module`.
const babelLoaderConfiguration = {
  test: /\.js$/,// Add every directory that needs to be compiled by Babel during the build.
  include: [
    path.resolve(appDirectory,'index.web.js'),path.resolve(appDirectory,'src'),'node_modules/react-native-uncompiled'),],use: {
    loader: 'babel-loader',options: {
      cacheDirectory: true,// The 'metro-react-native-babel-preset' preset is recommended to match React Native's packager
      presets: ['module:metro-react-native-babel-preset'],// Re-write paths to import only the modules needed by the app
      plugins: ['react-native-web'],},};

// This is needed for webpack to import static images in JavaScript files.
const imageLoaderConfiguration = {
  test: /\.(gif|jpe?g|png|svg)$/,use: {
    loader: 'url-loader',options: {
      name: '[name].[ext]',};

module.exports = {
  entry: [
    // load any web API polyfills
    // path.resolve(appDirectory,'polyfills-web.js'),// your web-specific entry file
    path.resolve(appDirectory,'src/index.js'),// configures where the build ends up
  output: {
    filename: 'bundle.web.js',path: path.resolve(appDirectory,'dist'),// ...the rest of your config

  module: {
    rules: [babelLoaderConfiguration,imageLoaderConfiguration],resolve: {
    // This will only alias the exact import "react-native"
    alias: {
      'react-native$': 'react-native-web',// If you're working on a multi-platform React Native app,web-specific
    // module implementations should be written in files using the extension
    // `.web.js`.
    extensions: ['.web.js','.js'],};
