vue-cli 4.2

index.html

<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width,initial-scale=1.0">
    <link rel="stylesheet" type="text/css" href="./iconfont.css" />
    <link rel="icon" href="<%= BASE_URL %>favicon.ico">
    <title><%= htmlWebpackPlugin.options.title %></title>
  </head>

title标签里写<%= htmlWebpackPlugin.options.title %>

vue.config.js

    config.plugin('html')
      .tap(args => {
        args[0].title= '数据可视化'
        return args
      })
