打包脚本的入口
以webpack进行脚本编译，通过--config 指定构建脚本配置
{
...
"scripts": {
...
"build:examples:web": "webpack --config build/webpack.examples.web.config.js",
"build:ci:web": "webpack --watch --config build/webpack.ci.web.config.js",
"dev:examples:web": "webpack --watch --config build/webpack.examples.web.config.js",
"serve": "serve ./ -p 12580",
... }
webpack 配置文件中 export 内容
entry，配置对应的 demo 例子
entry: {
'examples/build/web/vue-bundle': path.resolve('examples/vue', 'entry.js')
}
output.path生成文件结果对应的目录，.表示项目ROOT目录下面
output.filename为entry对应的ownProperty（比如：examples/build/web/vue-bundle）
modules.loaders用来指定文件解析器
plugins: 指定webpack对应的插件
module.exports = {
entry: entry,
output: {
path: '.',
filename: '[name].js'
},
module: {
loaders: [
{
test: /\.js$/,
loaders: ['babel-loader'],
exclude: /node_modules/
}, {
test: /\.vue(\?[^?]+)?$/,
loaders: ['vue-loader']
}
]
},
vue: {
optimizeSSR: false,
/**
* important! should use postTransformNode to add $processStyle for
* inline style prefixing.
*/
compilerModules: [
{
postTransformNode: el => {
el.staticStyle = `$processStyle(${el.staticStyle})`
el.styleBinding = `$processStyle(${el.styleBinding})`
}
}
],
},
plugins: [bannerPlugin],
watch:true
}
bannerPlugin 插件对应的实现
var webpack = require('webpack');
var banner = '// NOTE: for vue2.0 and platform:web only.\n'
var bannerPlugin = new webpack.BannerPlugin(banner, {
raw: true,
exclude: bannerExcludeFiles
})
module.loaders 定义代码文件的解析规则
在
package.json中对编译依赖的组件进行引入
"devDependencies": {
...
"babel-loader": "^6.2.5",
"css-loader": "^0.26.1",
"json-loader": "^0.5.4",
"vue-loader": "^12.2.1",
"webpack": "^1.13.1",
"weex-loader": "^0.5.3",
"weex-vue-render": "^0.12.32",
...
}
配置需要引用的
xxxx-loader
根据每一项 loader 规则中的 test 进行正则匹配
module.exports = {
module: {
loaders: [
{ test: /\.js$/,
loaders: ['babel-loader'],
exclude: /node_modules/
}, {
test: /\.vue(\?[^?]+)?$/,
loaders: ['vue-loader']
}
] }
entry.name的规则和定义
-
[name]: 获取到文件路径（包括相对目录和文件名） -
[chunkhash:X]: 获取文件 hash 串， x 表示需要留多少位

webpack 收集需要构建文件
var entry = {};
var webSrcDirectory = path.join(__dirname, '../examples/web-entry');
function getEntryFileContent (entryPath, vueFilePath) {
...
}
function walk(dir) {
dir = dir || '.';
var directory = path.join(__dirname, '../examples', dir);
var entryDirectory = path.join(webSrcDirectory, dir);
fs.readdirSync(directory)
.forEach(function(file) {
var fullpath = path.join(directory, file);
var stat = fs.statSync(fullpath);
var extname = path.extname(fullpath);
if (stat.isFile() && extname === '.vue') {
var entryFile = path.join(entryDirectory, path.basename(file, extname) + '.js');
fs.outputFileSync(entryFile, getEntryFileContent(entryFile, fullpath));
var name = path.join('examples', 'build/vue-web', /*path.relative('vue', dir)*/dir, path.basename(file, extname));
entry[name] = entryFile + '?entry=true';
} else if (stat.isDirectory() && file !== 'build' && file !== 'include') {
var subdir = path.join(dir, file);
walk(subdir);
}
});
}
walk();
用于展示 web 的代码入口文件生成
function getEntryFileContent (entryPath, vueFilePath) {
const relativePath = path.relative(path.join(entryPath, '../'), vueFilePath);
return 'var App = require(\'' + relativePath + '\')\n'
+ 'App.el = \'#root\'\n'
+ 'new Vue(App)\n'
}
通过 debug webpack 来获取各个目录信息
