Syndicode used to share with you new and interesting tools we’ve found. Automate getting valuable information about your app with Headless Devlools. This tool lets you perform Chrome DevTools actions from code by leveraging Headless Chrome+Puppeteer.
Using headless-devtools you can automate the process of getting valuable information about your app.
Some tools that provide similar metrics work by executing right after the page loads. This can lead to a skewed perception because these metrics don’t mean much unless the user has interacted with the page (some CSS rules weren’t applied, JS wasn’t executed, etc.).
To fix this, headless-devtools lets you mimic the user interacting with the page before\during when data is collected.
