webpack配置
const path = require('path')
const htmlWebpackPlugin = require('html-webpack-plugin')
const webpack = require('webpack')
const VueLoaderPlugin = require('vue-loader/lib/plugin')
module.exports = {
//__dirname动态获取当前文件模块所属目录的绝对路径
//__filename可以获取当前文件的绝对路径
entry:path.join(__dirname,'./src/main.js'),
output:{
path:path.join(__dirname,'./dist/'),
filename:'bundle.js' //指定输出文件的名称
},
resolve:{
alias:{
//修改Vue被导入的路径
"vue$":"vue/dist/vue.js",
"@u": path.resolve("src/utils"),
}
},
//该节点用于所有第三方模块加载器
module:{

devServer: {
contentBase: path.join(__dirname, 'src'),
host:'localhost',
port:3000,
proxy: {
'/api': { // api表示当前项目请求的key
target: 'http://novel.juhe.im', // 代理服务器路径

将路径或路径片段处理成绝对路径
生成的路径会进行规范化,并且删除末尾的斜杠,除非路径是根目录。
path.resolve('/foo/bar', './baz');
// 返回: '/foo/bar/baz
path.resolve('wwwroot', 'static_files/png/', '../gif/image.gif');
// 如果当前工作目录是 /home/myself/node,则返回 '/home/myself/node/wwwroot/static_files/gif/image.gif'
