Hello.

I integrated the Squoosh CLI into my web app to optimize images. Although Squoosh offers a great CLI, I needed its functionality within my app. Leveraging my experience with FFMPEG in web apps, I adapted the Squoosh CLI code, replacing Node.js dependencies with web APIs. Now, I can call Squoosh's 'run' method directly in my app to resize and compress images. This unofficial solution works for now, but a dedicated browser API would be ideal for broader integration in CMS platforms, performance analysis tools, and other web applications.

I've created Puppeteer Go, a small JavaScript library to simplify the process of creating CLI utilities with Puppeteer. It handles the boilerplate of launching the browser, opening a tab, navigating to a URL, performing a specified action, and cleaning up. This post demonstrates its usage by taking multiple screenshots of elements on a page, inspired by Ire Aderinokun's work. Examples include capturing screenshots of h1 elements on my blog and feature blocks on caniuse.com.
