Deno Deploy Cheat Sheet

Last Updated: November 21, 2025

Deployment Flow

Step	Action
`deno init`	Create entrypoint + config
`Deploy URL`	Pushing to `deno deploy` publishes to an immutable SHA
`Secrets`	Use dashboard or CLI to attach env vars


         deno task start

Run the dev server


         deno test

Execute tests before deploying


         deno deploy --allow-net --allow-env

Push to edge with permissions

Pin lockfile, grant only needed permissions, rotate tokens, and keep entrypoints small.

💡 Pro Tip: Use `deno task` for reproducible builds and pin deps via `lock.json`.
