前端异常监控

为什么需要前端异常监控

如今Web庞大复杂应用场景广泛，再加上各种浏览器造成的环境差异，很难保证我们的页面呈现给每个用户时都是正常的。稳定和准确是每个产品的基础，对于用户直接交互的页面更加显得重要。我们不能等到用户投诉后才知道出现问题，而是应该主动监控尽快暴露出异常。

前端有哪些异常

• 静态资源加载异常
  • 网络环境恶劣
  • 运营商劫持
  • 文件丢失

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event))

/**
 * Entry point of the worker
 */
async function handleRequest(event) {
  try {
    // Get the JWT

function interceptNetworkRequests(ee) {
    const open = XMLHttpRequest.prototype.open;
    const send = XMLHttpRequest.prototype.send;

    const isRegularXHR = open.toString().indexOf('native code') !== -1;


    // don't hijack if already hijacked - this will mess up with frameworks like Angular with zones
    // we work if we load first there which we can.
    if (isRegularXHR) {
