weexapp 开发流程（一）开发环境配置

1.创建项目

weexpack create weexapp

2.安装必要插件

npm i jwt-simple vue-resource vue-router vuex vuex-router-sync weex-ui -S

npm i babel-plugin-component babel-preset-stage-0 history quick-local-ip weex-builder weex-router -D

3.修改 scripts 指令

package.json

"scripts": {
    "build": "webpack",
    "build_plugin": "webpack --config ./tools/webpack.config.plugin.js --color",
    "dev": "webpack --config webpack.config.js --watch",
    "serve": "webpack-dev-server --config webpack.dev.js --progress --watch --open",
    "start": "webpack && webpack-dev-server --config webpack.dev.js --progress --watch --open",
    "create": "weexpack run android"
},

4.配置 weex-ui

.babelrc

{
  "presets": ["es2015", "stage-0"],
  "plugins": [
    [
      "component",
      {
        "libraryName": "weex-ui",
        "libDir": "packages"
      }
    ]
  ]
}

5.修改 webpack 模块管理

webpack.config.js

步骤一：

步骤二：

步骤三：

步骤四：

步骤五：

修改后：

webpack.config.js

const pathTo = require('path');
const fs = require('fs-extra');
const webpack = require('webpack');

const entry = {index: pathTo.resolve('src', 'entry.js')};
const weexEntry = {index: pathTo.resolve('src', 'entry.js')};
const vueWebTemp = 'temp';
const hasPluginInstalled = fs.existsSync('./web/plugin.js');
var isWin = /^win/.test(process.platform);

function getEntryFileContent(entryPath, vueFilePath) {
    let relativePath = pathTo.relative(pathTo.join(entryPath, '../'), vueFilePath);
    let contents = '';
    if (hasPluginInstalled) {
        const plugindir = pathTo.resolve('./web/plugin.js');
        contents = 'require(\'' + plugindir + '\') \n';
    }
    if (isWin) {
        relativePath = relativePath.replace(/\\/g,'\\\\');
    }
    contents += 'var App = require(\'' + relativePath + '\')\n';
    contents += 'App.el = \'#root\'\n';
    contents += 'new Vue(App)\n';
    return contents;
}

var fileType = '';

function walk(dir) {
    dir = dir || '.';
    const directory = pathTo.join(__dirname, 'src', dir);
    fs.readdirSync(directory)
        .forEach((file) => {
            const fullpath = pathTo.join(directory, file);
            const stat = fs.statSync(fullpath);
            const extname = pathTo.extname(fullpath);
            const basename = pathTo.basename(fullpath);
            if (stat.isFile() && extname === '.vue' && basename != 'App.vue' ) {
                if (!fileType) {
                    fileType = extname;
                }
                if (fileType && extname !== fileType) {
                    console.log('Error: This is not a good practice when you use ".we" and ".vue" togither!');
                }
                const name = pathTo.join(dir, pathTo.basename(file, extname));
                if (extname === '.vue') {
                    const entryFile = pathTo.join(vueWebTemp, dir, pathTo.basename(file, extname) + '.js');
                    fs.outputFileSync(pathTo.join(entryFile), getEntryFileContent(entryFile, fullpath));

                    entry[name] = pathTo.join(__dirname, entryFile) + '?entry=true';
                }
                weexEntry[name] = fullpath + '?entry=true';
            } else if (stat.isDirectory() && ['build','include','assets','filters','mixins'].indexOf(file) == -1 ) {
                const subdir = pathTo.join(dir, file);
                walk(subdir);
            }
        });
}

walk();
// web need vue-loader
const plugins = [
    new webpack.optimize.UglifyJsPlugin({minimize: true}),
    new webpack.BannerPlugin({
        banner: '// { "framework": ' + (fileType === '.vue' ? '"Vue"' : '"Weex"') + '} \n',
        raw: true,
        exclude: 'Vue'
    })
];
const webConfig = {
    context: pathTo.join(__dirname, ''),
    entry: entry,
    output: {
        path: pathTo.join(__dirname, 'dist'),
        filename: '[name].web.js',
    },
    module: {
        // webpack 2.0
        rules: [
            {
                test: /\.js$/,
                use: [{
                    loader: 'babel-loader',
                    options: {
                        presets: ['es2015']
                    }
                }]
            },
            {
                test: /\.css$/,
                use: [{
                    loader: 'css-loader'
                }]
            },
            {
                test: /\.vue(\?[^?]+)?$/,
                use: [{
                    loader: 'vue-loader'
                }]
            }
        ]
    },
    plugins: plugins
};
const weexConfig = {
    entry: weexEntry,
    output: {
        path: pathTo.join(__dirname, 'dist'),
        filename: '[name].js',
    },
    module: {
        rules: [
            {
                test: /\.js$/,
                use: [{
                    loader: 'babel-loader',
                }]
            },
            {
                test: /\.vue(\?[^?]+)?$/,
                use: [{
                    loader: 'weex-loader'
                }]
            },
            {
                test: /\.we(\?[^?]+)?$/,
                use: [{
                    loader: 'weex-loader'
                }]
            }
        ],
    },
    plugins: plugins,
};

var exports = [webConfig, weexConfig];

module.exports = exports;

6.修改 webpack 开发环境文件

webpack.dev.js

const ip = require('quick-local-ip').getLocalIP4();
const configs = require('./webpack.config.js');
const webpack = require('webpack');
const pathTo = require('path');
const chalk = require('chalk');
let config = Array.isArray(configs) ? configs[0] : configs;
config.devServer = {
    contentBase: pathTo.join(__dirname, ''),
    compress: true,
    // hot: true,
    host: '0.0.0.0',
    public: ip + ':8080/web',
    // publicPath: '/dist/',
};
// configs.plugins.push(new webpack.HotModuleReplacementPlugin());
console.log('server is running! Please open ' + chalk.green('http://' + ip + ':8080/web/index.html'));
module.exports = config;

7.提取 weex-ui 组件
