Dump HTML after page load

To dump the HTML of the whole page after the page is completely loaded. This can be particularly useful when loading a dynamic page where data is loaded via AJAX.

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

CDP(async(client) => {
    const {Network, Page, Runtime} = client;
    try {
        await Network.enable();
        await Page.enable();
        await Network.setCacheDisabled({cacheDisabled: true});
        await Page.navigate({url: 'https://github.com'});
        await Page.loadEventFired();
        const result = await Runtime.evaluate({
            expression: 'document.documentElement.outerHTML'
        });
        const html = result.result.value;
        console.log(html);
    } catch (err) {
        console.error(err);
    } finally {
        client.close();
    }
}).on('error', (err) => {
    console.error(err);
});
