< p > Puppeteer is a Node.js library which provides a high-level API to control
Chrome/Chromium over the
< a href = "https://chromedevtools.github.io/devtools-protocol/" target = "_blank" rel = "noopener noreferrer" > DevTools Protocol< / a > .
Puppeteer runs in
< a href = "https://developer.chrome.com/docs/chromium/new-headless/" target = "_blank" rel = "noopener noreferrer" > headless< / a >
mode by default, but can be configured to run in full (" headful" )
Chrome/Chromium.< / p >
< h1 > Features< / h1 >
< p > Most things that you can do manually in the browser can be done using Puppeteer!
Here are a few examples to get you started:< / p >
< ul >
< li > Automate form submission, UI testing, keyboard input, etc.< / li >
< li > Create an automated testing environment using the latest JavaScript and
browser features.< / li >
< li > Capture a

of your site to help diagnose performance issues.< / li >
< li > < a href = "https://pptr.dev/guides/chrome-extensions" target = "_blank" rel = "noopener noreferrer" > Test Chrome Extensions< / a > .< / li >
< li > Generate screenshots and PDFs of pages.< / li >
< li > Crawl a SPA (Single-Page Application) and generate pre-rendered content (i.e.
" SSR" (Server-Side Rendering)).< / li >
