问题 Okay, I'm a newbie to all this so any help greatly appreciated. I've managed to use Node and Express to serve up Polymer Starter Kit (PSK) website from the Polymer build directory from a file I created in the home directory (server.js): // Node.js notation for importing packages var express = require('express'); // Spin up a server var app = express(); // Serve static files from the main build directory app.use(express.static(__dirname + '/build/es5-bundled')); // Render index.html on the

Thus I want a more lightweight method hence the use of the docker image. For Karma, according to the docs, I must specify a script for the browser if i want to use a custom browser. Also Karma will pass 1 argument to this script, the url. For this requirement I also pulled the browserless docker image

问题 https://github.com/GoogleChrome/puppeteer/blob/master/examples/custom-event.js shows how to define your own event, but doesn't show how to transmit event data back to the code outside Puppeteer.

问题 I'm using this code to log the encoded response size when loading a page in Chrome: const puppeteer = require("puppeteer"); (async function() { const browser = await puppeteer.launch(); const page = await browser.newPage(); page._client.on("Network.loadingFinished", data => { console.log("finished", { encodedDataLength: data.encodedDataLength }); }); // await page.setRequestInterception(true); // page.on("request", async request => { // request.continue(); // }); await page.goto("http:/
