主要是下面代码片段的添加和修改
config.plugin('html').tap(args => {
// 添加初始化变量
args[0].monitorId = process.env.VUE_APP_MONITOR_ID
return args
})
<script>
Performance({
domain: 'http://frontend-monitor.xxxxxx.com/api/v1/xxxxx/web',
add:{
// appId:'XndJYYxxxx028xxxxxx04' // 改前 生成的其应用的appid
appId:'<%= htmlWebpackPlugin.options.monitorId %>' // 改后 生成的其应用的appid 在这里使用就是根据不同的环境，获取不同的值 对应.env.production和.env.development中的常量值
}
})
