Live Code with Kevin: Astro on Deno @deno

Uploaded July 2023 | Updated September 2026, 1 week ago

Today, we are going to take a quick detour from our previous example application to look at something else I've been working on - a new template and documentation for Astro (https://www.astro.build). We'll walk through the new template, some of the challenges I encountered building it, and show how we deploy an Astro site on Deno Deploy.

$Safe Cloud Code Execution with Snapshots (Python Pre-Installed, Zero Wait) Deno Sandbox lets you spin up isolated cloud VMs programmatically. With the snapshots feature, you can pre-install an entire environment once and boot it without waiting for installs every time after. In this video I show you the snapshot workflow end to end: → Create a cloud volume and boot a sandbox → Install Python, and required packages and build tools → Snapshot the volume — your environment is now frozen and reusable → Boot fresh sandboxes from that snapshot instantly, with everything pre-installed As a demo we run a live interactive Mandelbrot fractal explorer. An HTTP server deployed entirely inside the sandbox, the code never touching the host machine. This is the foundation for safe execution of AI-generated code, user-submitted scripts, or any workload you want fully isolated and reproducible.
