What is chrome-launcher?

The chrome-launcher npm package is a tool that allows developers to automate the launching of Google Chrome with specific configurations. It is often used for running automated tests, scraping websites, and automating interactions with web pages.

What are chrome-launcher's main functionalities?

Launching Chrome

This feature allows you to launch a new instance of Chrome. The code sample demonstrates how to launch Chrome with a starting URL.

const chromeLauncher = require('chrome-launcher');

async function launchChrome() {
  const chrome = await chromeLauncher.launch({startingUrl: 'https://example.com'});
  console.log(`Chrome debugging port running on ${chrome.port}`);
}

launchChrome();

Custom Chrome Flags

This feature enables the use of custom flags when launching Chrome. The code sample shows how to launch Chrome in headless mode with GPU disabled.

const chromeLauncher = require('chrome-launcher');

async function launchChromeWithFlags() {
  const chrome = await chromeLauncher.launch({
    chromeFlags: ['--headless', '--disable-gpu']
  });
  console.log(`Chrome debugging port running on ${chrome.port}`);
}

launchChromeWithFlags();

Killing Chrome Instances

This feature allows you to programmatically kill the launched Chrome instance. The code sample illustrates launching Chrome and then killing it after some operations.

const chromeLauncher = require('chrome-launcher');

async function launchAndKillChrome() {
  const chrome = await chromeLauncher.launch({startingUrl: 'https://example.com'});
  console.log(`Chrome debugging port running on ${chrome.port}`);

  // Some time later...
  await chrome.kill();
}

launchAndKillChrome();
