How to Deploy to Deno Deploy: Simple Steps for Your Deno App

To deploy to Deno Deploy, first install the deno CLI, then log in using deno deploy login. Finally, run deno deploy --project= in your project folder to upload and host your app instantly.

Syntax

The basic command to deploy your app to Deno Deploy is:

deno deploy --project=<project-name>

Here:

• deno deploy is the command to start deployment.
• --project=<project-name> specifies your Deno Deploy project name.

Before deploying, you must log in with deno deploy login to authenticate your account.

bash

deno deploy --project=my-deno-app

Example

This example shows how to deploy a simple Deno HTTP server to Deno Deploy.

First, create a file app.ts with a basic server:

typescript

import { serve } from "https://deno.land/std@0.203.0/http/server.ts";

serve((_req) => new Response("Hello from Deno Deploy!"));

Output

When accessed, the deployed app responds with: Hello from Deno Deploy!

Common Pitfalls

Common mistakes when deploying to Deno Deploy include:

• Not logging in before deploying, causing authentication errors.
• Using an incorrect or missing --project name.
• Deploying files with syntax errors or unsupported APIs.
• Not specifying the entry file correctly if your project has multiple files.

Always check your code runs locally with deno run before deploying.

bash

Wrong:

deno deploy

Right:

deno deploy --project=my-deno-app

Quick Reference

Command	Description
deno deploy login	Log in to your Deno Deploy account

Key Takeaways

Always log in with 'deno deploy login' before deploying.

Use 'deno deploy --project=' to deploy your app.

Test your app locally with 'deno run' to avoid runtime errors.

Specify the correct project name to prevent deployment failures.

Keep your code simple and compatible with Deno Deploy environment.
