项目中使用到了react-web,有空记录下使用步骤.
react-web是淘宝前端团队开发的一个可以把react-native转换成web的工具,大体上能实现了移动端的iOS/安卓/移动web这三端的代码共用. 当然细节上是充满了各种有解无解的坑.
安装
安装命令行工具react-web-cli : npm install react-web-cli -g
-
在package.json 文件里添加以下内容后npm install "dependencies": {
...
"react-dom": "15.3.x","react-web": "0.4.6"
},"devDependencies": {
...
"babel-loader": "^6.2.5","babel-preset-react-native": "^1.9.0","babel-preset-stage-1": "^6.16.0","haste-resolver-webpack-plugin": "^0.2.2","json-loader": "^0.5.4","react-hot-loader": "^1.3.0","webpack": "^1.13.2","webpack-dev-server": "^1.16.1","webpack-html-plugin": "^0.1.1"
}
-
项目目录下创建web文件夹,里面创建webpack.config.js 文件,内容: 'use strict';
var path = require('path');
var webpack = require('webpack');
var HtmlPlugin = require('webpack-html-plugin');
var HasteResolverPlugin = require('haste-resolver-webpack-plugin');
var IP = '0.0.0.0';
var PORT = 3000;
var NODE_ENV = process.env.NODE_ENV;
var ROOT_PATH = path.resolve(__dirname,'..');
var PROD = 'production';
var DEV = 'development';
let isProd = NODE_ENV === 'production';
var config = {
paths: {
src: path.join(ROOT_PATH,'.'),index: path.join(ROOT_PATH,'index.web'),},};
var webpackConfig = {
ip: IP,port: PORT,devtool: 'cheap-module-eval-source-map',resolve: {
alias: {
'react-native': 'ReactWeb',extensions: ['','.js','.web.js','.ios.js','.android.js','.native.js','.jsx'],entry: isProd ? [
config.paths.index
] : [
'webpack-dev-server/client?http://' + IP + ':' + PORT,'webpack/hot/only-dev-server',config.paths.index,],output: {
path: path.join(__dirname,'output'),filename: 'bundle.js'
},plugins: [
new HasteResolverPlugin({
platform: 'web',nodeModules: ['react-web']
}),new webpack.DefinePlugin({
'process.env': {
'NODE_ENV': JSON.stringify(isProd ? PROD : DEV),}
}),isProd ? new webpack.ProvidePlugin({
React: 'react'
}) : new webpack.HotModuleReplacementPlugin(),new webpack.NoErrorsPlugin(),new HtmlPlugin(),module: {
loaders: [{
test: /.json$/,loader: 'json',{
test: /.jsx?$/,loader: 'react-hot',include: [config.paths.src],exclude: [/node_modules/]
},loader: 'babel',query: {
presets: ['react-native','stage-1']
},exclude: [path.sep === '/' ? /(node_modules/(?!react-))/ : /(node_modules(?!react-))/]
}]
}
};
webpackConfig.resolve.alias[path.basename(ROOT_PATH,'.')] = path.join(ROOT_PATH,'.');
module.exports = webpackConfig;
-
项目目录下创建index.web.js 文件,把index.ios.js 内容copy过来,在最后加上以下代码: if (Platform.OS == 'web') {
var app = document.createElement('div');
document.body.appendChild(app);
AppRegistry.runApplication('Helloworld',{
rootTag: app
});
}
-
在项目目录下命令react-web start ,成功后在浏览器打开http://localhost:3000 就能看到了.
测试并打包 Web 版本代码
-
打包html: react-web bundle
打包完成后,文件会存放在 web/output/ 目录下面.
安装有http-server 工具的可以在output文件夹下命令http-server ,再在浏览器输入http://127.0.0.1:8080/ 就能看到了.
