基于Vue.js的大型报告页项目实现过程及问题总结一

今年5月份的时候做了一个测评报告项目，需要在网页正常显示的同时且可打印为pdf，当时的技术方案采用jquery+template的方式，因为是固定模板所以并没有考虑报告的模块化区分，九月底产品提出新的需求，由于报告页数动辄上千页，所以希望用户自行选择内容生成报告，这个时候原项目就不够灵活了，与小伙伴商量决定将这个项目使用vue进行重构，对报告模块进行细分封装组件复用，大概一个月的工期，中途遇到n多坑，趁着今天有时间将实现思路整理出来并将出现的问题总结一下

整体的实现思维导图如下：

：转PDF插件使用的是具体配置方法可自行百度，在这里不过多赘述。

）：

1123*793），在使用

vue init webpack vuetest

命令输入后，会进入安装阶段，需要用户输入一些信息

Project name (vuetest) 项目名称，可以自己指定，也可直接回车，按照括号中默认名字（注意这里的名字不能有大写字母，如果有会报错Sorry,name can no longer contain capital letters），阮一峰老师博客，可以参考一下。

Project description (A Vue.js project) 项目描述，也可直接点击回车，使用默认名字

Author (........) 作者，不用说了，你想输什么就输什么吧

接下来会让用户选择

Runtime + Compiler: recommended for most users 运行加编译，既然已经说了推荐，就选它了

Runtime-only: about 6KB lighter min+gzip,but templates (or any Vue-specificHTML) are ONLY allowed in .vue files - render functions are required elsewhere 仅运行时，已经有推荐了就选择第一个了

Install vue-router? (Y/n) 是否安装vue-router，这是官方的路由，大多数情况下都使用，。这里就输入“y”后回车即可。

Use ESLint to lint your code? (Y/n) 是否使用ESLint管理代码，ESLint是个代码风格管理工具，是用来统一代码风格的，并不会影响整体的运行，这也是为了多人协作，新手就不用了，一般项目中都会使用。

接下来也是选择题Pick an ESLint preset (Use arrow keys) 选择一个ESLint预设，编写vue项目时的代码风格，因为我选择了使用ESLint

Standard (https://github.com/feross/standard) 标准，有些看不明白，什么标准呢，去给提示的 github地址看一下，原来时js的标准风格

AirBNB (https://github.com/airbnb/javascript) JavaScript最合理的方法，这个github地址说的是JavaScript最合理的方法

none (configure it yourself) 这个不用说，自己定义风格

具体选择哪个因人而异吧，我选择标准风格

Setup unit tests with Karma + Mocha? (Y/n) 是否安装单元测试，我选择安装

Setup e2e tests with Nightwatch(Y/n)? 是否安装e2e测试，我选择安装

完成

初始的目录结构大概是这样的

由于是多页面应用所以需要在src下建一个modle文件夹里面是两个不同的项目

这里的index.html是入口文件，一定不能少，这这里做中转默认进入demo1的页面

下面对多页面进行配置，主要操作config和build这两个文件夹

/build
    build

生成需要的入口文件

var path = require('path')var config = require('../config')var utils = require('./utils')var projectRoot = path.resolve(__dirname,'../')var glob = require('glob');var entries = getEntry(['./src/demo1/index/.js','./src/module/demo2/.js']); // 获得入口js文件

var env = process.env.NODE_ENV// check env & config/index.js to decide weither to enable CSS Sourcemaps for the// various preprocessor loaders added to vue-loader at the end of this filevar cssSourceMapDev = (env === 'development' && config.dev.cssSourceMap)var cssSourceMapProd = (env === 'production' && config.build.productionSourceMap)var useCssSourceMap = cssSourceMapDev || cssSourceMapProd

module.exports = { entry: entries, output: { path: config.build.assetsRoot, publicPath: process.env.NODE_ENV === 'production' ? config.build.assetsPublicPath : config.dev.assetsPublicPath, filename: '[name].js' }, resolve: { extensions: ['','.js','.vue','.json'], fallback: [path.join(__dirname,'../node_modules')], alias: { 'vue$': 'vue/dist/vue', 'src': path.resolve(dirname,'../src'), 'common': path.resolve(dirname,'../src/common'), 'components': path.resolve(dirname,'../src/components') } }, resolveLoader: { fallback: [path.join(dirname,'../node_modules')] }, module: { loaders: [{ test: /\.vue$/, loader: 'vue' }, { test: /\.js$/, loader: 'babel', include: projectRoot, exclude: /node_modules/ }, { test: /\.json$/, loader: 'json' }, { test: /\.(png|jpe?g|gif|svg)(\?.)?$/, loader: 'url', query: { limit: 10000, name: utils.assetsPath('img/[name].[hash:7].[ext]') } }, { test: /\.(woff2?|eot|ttf|otf)(\?.)?$/, name: utils.assetsPath('fonts/[name].[hash:7].[ext]') } } ] }, vue: { loaders: utils.cssLoaders({ sourceMap: useCssSourceMap }), postcss: [ require('autoprefixer')({ browsers: ['last 2 versions'] }) ] }}

function getEntry(globPath) { var entries = {}, basename,tmp,pathname; if (typeof (globPath) != "object") { globPath = [globPath] } globPath.forEach((itemPath) => { glob.sync(itemPath).forEach(function (entry) { basename = path.basename(entry,path.extname(entry)); if (entry.split('/').length > 4) { tmp = entry.split('/').splice(-3); pathname = tmp.splice(0,1) + '/' + basename; // 正确输出js和html的路径 entries[pathname] = entry; } else { entries[basename] = entry; } }); }); return entries;}

修改本地开发的webpack配置webpack.dev.conf.js

这里是和本地服务器有关的配置

这里是根据目录生成对应的页面

var path = require('path');var config = require('../config')var webpack = require('webpack')var merge = require('webpack-merge')var utils = require('./utils')var baseWebpackConfig = require('./webpack.base.conf')var HtmlWebpackPlugin = require('html-webpack-plugin')var glob = require('glob')// add hot-reload related code to entry chunksObject.keys(baseWebpackConfig.entry).forEach(function (name) { baseWebpackConfig.entry[name] = ['./build/dev-client'].concat(baseWebpackConfig.entry[name])})module.exports = merge(baseWebpackConfig,{ module: { loaders: utils.styleLoaders({ sourceMap: config.dev.cssSourceMap }) }, // eval-source-map is faster for development devtool: '#eval-source-map', plugins: [ new webpack.DefinePlugin({ 'process.env': config.dev.env }), // https://github.com/glenjamin/webpack-hot-middleware#installation--usage new webpack.optimize.OccurenceOrderPlugin(), new webpack.HotModuleReplacementPlugin(), new webpack.NoErrorsPlugin() ]})

function getEntry(globPath) { var entries = {},1) + '/' + basename; // 正确输出js和html的路径 entries[pathname] = entry; } else { entries[basename] = entry; } }); }); return entries;}

var pages = getEntry(['./src/module/*.html','./src/module/**/*.html']);

for (var pathname in pages) { // 配置生成的html文件，定义路径等 var conf = { filename: pathname + '.html', template: pages[pathname],// 模板路径 inject: true,// js插入位置 // necessary to consistently work with multiple chunks via CommonsChunkPlugin chunksSortMode: 'dependency'

};

if (pathname in module.exports.entry) { conf.chunks = ['manifest','vendor',pathname]; conf.hash = true; }

module.exports.plugins.push(new HtmlWebpackPlugin(conf));}

path = require('path' config = require('../config' utils = require('./utils' webpack = require('webpack' merge = require('webpack-merge' baseWebpackConfig = require('./webpack.base.conf' ExtractTextPlugin = require('extract-text-webpack-plugin' HtmlWebpackPlugin = require('html-webpack-plugin' CleanPlugin = require('clean-webpack-plugin') glob = require('glob' env =var webpackConfig = merge(baseWebpackConfig,{
module: {
loaders: utils.styleLoaders({ sourceMap: config.build.productionSourceMap,extract: true })
},devtool: config.build.productionSourceMap ? '#source-map' : false,output: {
path: config.build.assetsRoot,filename: utils.assetsPath('js/[name].[chunkhash].js'),chunkFilename: utils.assetsPath('js/[id].[chunkhash].js')
},vue: {
loaders: utils.cssLoaders({
sourceMap: config.build.productionSourceMap,extract: true
})
},plugins: [
// http://vuejs.github.io/vue-loader/workflow/production.html
new webpack.DefinePlugin({
'process.env': env
}),new webpack.optimize.UglifyJsPlugin({
compress: {
warnings: false
}
}),new CleanPlugin(['../dist']),//清空生成目录
new webpack.optimize.OccurenceOrderPlugin(),// extract css into its own file
new ExtractTextPlugin(utils.assetsPath('css/[name].[contenthash].css')),// generate dist index.html with correct asset hash for caching.
// you can customize output by editing /index.html
// see https://github.com/ampedandwired/html-webpack-plugin
// split vendor js into its own file
new webpack.optimize.CommonsChunkPlugin({
name: 'vendor',minChunks: function (module,count) {
// any required modules inside node_modules are extracted to vendor
return (
module.resource &&
/.js$/.test(module.resource) &&
module.resource.indexOf(
path.join(__dirname,'../node_modules')
) === 0
)
}
}),// extract webpack runtime and module manifest to its own file in order to
// prevent vendor hash from being updated whenever app bundle is updated
new webpack.optimize.CommonsChunkPlugin({
name: 'manifest',chunks: ['vendor']
})
]
})

if (config.build.productionGzip) {
var CompressionWebpackPlugin = require('compression-webpack-plugin')

webpackConfig.plugins.push(
new CompressionWebpackPlugin({
asset: '[path].gz[query]',algorithm: 'gzip',test: new RegExp(
'\.(' +
config.build.productionGzipExtensions.join('|') +
')$'
),threshold: 10240,minRatio: 0.8
})
)
}

module.exports = webpackConfig

function getEntry(globPath) {
var entries = {},basename,pathname;
if (typeof (globPath) != "object") {
globPath = [globPath]
}
globPath.forEach((itemPath) => {
glob.sync(itemPath).forEach(function (entry) {
basename = path.basename(entry,path.extname(entry));
if (entry.split('/').length > 4) {
tmp = entry.split('/').splice(-3);
pathname = tmp.splice(0,1) + '/' + basename; // 正确输出js和html的路径
entries[pathname] = entry;
} else {
entries[basename] = entry;
}
});
});
return entries;
}

var pages = getEntry(['./src/module/.html','./src/module//.html']);

for (var pathname in pages) {
// 配置生成的html文件，定义路径等
var conf = {
filename: pathname + '.html',template: pages[pathname],// 模板路径
inject: true,// js插入位置
// necessary to consistently work with multiple chunks via CommonsChunkPlugin
chunksSortMode: 'dependency'
};

if (pathname in module.exports.entry) {
conf.chunks = ['manifest','vendor',pathname];
conf.hash = true;
}

module.exports.plugins.push(new HtmlWebpackPlugin(conf));
}

path = require('path' config = require('../config' utils = require('./utils' webpack = require('webpack' merge = require('webpack-merge' baseWebpackConfig = require('./webpack.base.conf' ExtractTextPlugin = require('extract-text-webpack-plugin' HtmlWebpackPlugin = require('html-webpack-plugin' CleanPlugin = require('clean-webpack-plugin') glob = require('glob' env =var webpackConfig = merge(baseWebpackConfig,pathname];
conf.hash = true;
}

module.exports.plugins.push(new HtmlWebpackPlugin(conf));
}

修改index.js

path = require('path'module.exports = {
build: {
env: require('./prod.env'),index: path.resolve(dirname,'../dist/index.html'),assetsRoot: path.resolve(dirname,'../dist'),assetsSubDirectory: 'static',assetsPublicPath: '../',productionSourceMap: true,// Gzip off by default as many popular static hosts such as
// Surge or Netlify already gzip all static assets for you.
// Before setting to `true`,make sure to:
// npm install --save-dev compression-webpack-plugin
productionGzip: false,productionGzipExtensions: ['js','css']
},dev: {
env: require('./dev.env'),port: 8080,assetsPublicPath: '/',proxyTable: {},// CSS Sourcemaps off by default because relative paths are "buggy"
// with this option,according to the CSS-Loader README
// (https://github.com/webpack/css-loader#sourcemaps)
// In our experience,they generally work as expected,
// just be aware of this issue when enabling this option.
cssSourceMap: false
}
}

ok，配置结束，一个基本的多页面应用已经成功建成

接下来就进入正题了，放在下一篇来写。。。。。。。
