1、首先需要node（去官网下载）
2、见一个文件夹 比如koa cmd——r cd koa文件
3、npm init
4、安装webpack （本地安装）
npm install --save-dev webpack
4.1、用webpack4+ 还需要安装webpack-cli
npm install --save-dev webpack-cli
5、安装koa （记住，package.json内的项目名称不能叫koa 否则安装不了koa）
npm install koa --save
6、安装其他依赖
npm install koa-compress --save
npm install koa-router --save
npm install koa-compress --save
npm install koa-static --save
package.json文件

app.js
const koaStatic = require("koa-static");
const compress = require("koa-compress");
const path = require("path");
const fs = require("fs");
const app = new Koa();
app.use(compress());
app.use(koaStatic(path.resolve(__dirname,"./")));
const router = koaRouter();
router.get("*",async(ctx,next)=>{
ctx.type="html",
ctx.body=fs.readFileSync(path.resolve(‘./dist/index.html‘),‘utf-8‘)
});
app.use(router.routes()).use(router.allowedMethods());
