Chrome-remote-interface: how to get This site can’t be reached event?

[gwuhaolin]

for example,let's run Page.navigate({url:'http://cant.reached.com'})
browser can't reach to this site,is there a event will be fired when site can’t be reached ?
from Page doc can't find any about it.

You need to keep track of the first request, if it fails then you can assume that the page is failed. AFAIK there's no easier way to accomplish that.

const CDP = require('chrome-remote-interface');

CDP(async (client) => {
    const {Page, Network} = client;
    let requestId;
    let failed = false;
    Network.requestWillBeSent((params) => {
        requestId = params.requestId;
    });
    Network.loadingFailed((params) => {
        if (params.requestId === requestId) {
            failed = true;
        }
    });
    Page.loadEventFired(() => {
        if (failed) {
            console.log('FAIL');
        } else {
            console.log('OK');
        }
        client.close();
    });
    try {
        await Page.enable();
        await Network.enable();
        await Page.navigate({url: 'http://cantreached.com'});
    } catch (err) {
        console.error(err);
    }
}).on('error', (err) => {
    console.error(err);
});

Note cant.reached.com can actually be reached :)
