    My puppeteer scripts now use deno.

    No more need for npm in my personal stack! The native browser’s path comes from which.

    javascript
    import puppeteer from "https://deno.land/x/puppeteer@16.2.0/mod.ts";
    
    const chrome = "chromium";  // Browser Chrome: "firefox" | "chromium" | "google-chrome" | ...
    const product = "chrome";   // Product Base:   "firefox" | "chrome"
    
    const command = new Deno.Command("which", { args: [chrome] });
    const { status, stdout, stderr } = command.outputSync();
    const executablePath = new TextDecoder().decode(stdout).trim();
    
    const browser = await puppeteer.launch({
      headless: false,
      executablePath: executablePath,
      product: product,
    });
    
    const site = "example.com";
    const page = await browser.newPage();
    
    await page.setViewport({ width: 1024, height: 768 });
    await page.goto("https://" + site);
    await page.screenshot({ path: site + ".png" });
    
    await page.waitForSelector('a');
    
    const url = await page.evaluate(() => {
      return document.querySelector('a').href;
    });
    
    console.log(url);
    
    await browser.close();
    Basic Boilerplate: Captures a picture of example.com (main.ts)
    shell
    deno run --allow-all main.ts

    Web servers can be spun up quickly on the command line but with gotchas.

    Take the innocent web server .

    shell
    php -S 127.0.0.1:8080

    Best not to use PHP’s web server cli (even for PHP) because routes with a dot (.) are assumed to be static files. Use a real web server or superior cli web servers with minor gotchas.

    shell
    python -m http.server --bind 127.0.0.1 8080
    busybox httpd -f -p 127.0.0.1:8080
    ruby -run -e httpd . -p 8080

    One way to remove multi–page transition jank is to force a permanent scrollbar. Are there any kindred spirits? Yes — there’s a kindred spirit. Overflows may disable descending position: sticky behavior. Avoid that problem with other jank removal techniques.

    css
    html {
      overflow-y: scroll;
    }
    
    body {
      overflow-y: scroll;
    }
