My puppeteer scripts now use deno.

No more need for npm in my personal stack! spawnSync + which returns the local browser’s path.

  
  
    javascript
  
  
  import puppeteer from "https://deno.land/x/puppeteer@16.2.0/mod.ts";

const chrome = "firefox";   /* Browser Chrome: "firefox" | "chromium" | "google-chrome" | ... */
const product = "firefox";  /* Product Base:   "firefox" | "chrome" */

const { status, stdout, stderr } = Deno.spawnSync("which", {
  args: [ chrome, ],
});

const executablePath = new TextDecoder().decode(stdout).trim();

const browser = await puppeteer.launch({
  headless: false,
  executablePath: executablePath,
  product: product,
});

const page = await browser.newPage();
await page.setViewport({ width: 1024, height: 768, });

const sites = [ "example.com", ];

for (const site of sites) {
  await page.goto("http://" + site);
  await page.screenshot({ path: site + ".png" });
}

await browser.close();

shell

deno run --allow-all --unstable main.ts
