Astral is a Puppeteer/Playwright-like library designed with Deno in mind.

What can I do?

Most things that you can do manually in the browser can be done using Astral! Here are a few examples to get you started:

• Generate screenshots and PDFs of pages.
• Crawl a SPA (Single-Page Application) and generate pre-rendered content (i.e. "SSR" (Server-Side Rendering)).
• Automate form submission, UI testing, keyboard input, etc.
• Create a reproducable, automated testing environment using the latest JavaScript and browser features.
• Stealthy by default. No need to install or setup extra libraries to get features that should come by default.

Usage

Before we go into the depths of the API, let's see a quick demo first:

// Import Astral
import { launch } from "https://deno.land/x/astral/mod.ts";

// Launch the browser
const browser = await launch();

// Open a new page
const page = await browser.newPage("https://deno.land");

// Take a screenshot of the page and save that to disk
const screenshot = await page.screenshot();
Deno.writeFileSync("screenshot.png", screenshot);

// Close the browser
await browser.close();

You can run this from the command line using:

deno run -A https://deno.land/x/astral/examples/screenshot.ts
