vercel-deno-unstable v0.8.2

The Deno Runtime compiles a TypeScript or JavaScript function into a serverless function powered by Deno, running on Vercel.

Usage

Your serverless function file is expected to export default the HTTP handler function, and then vercel-deno takes care of invoking that handler function every time an HTTP request is received.

Note: Check out the api directory to see examples of using popular Deno web frameworks with vercel-deno. Feel free to send a pull request to add additional examples!

Example

Create a file called api/hello.ts with the following contents:

import { ServerRequest } from 'https://deno.land/std@0.70.0/http/server.ts';

export default async (req: ServerRequest) => {
	req.respond({ body: `Hello, from Deno v${Deno.version.deno}!` });
};

Next, define the vercel-deno runtime within the "functions" object in your vercel.json file:

{
	"functions": {
		"api/**/*.[jt]s": { "runtime": "vercel-deno@0.7.1" }
	}
}

Configuration

There are a few build environment variables that you may configure for your serverless functions:

Development

The vercel dev command is supported on Windows, macOS, and Linux:

• Vercel CLI v19.1.0 or newer is required.
• Uses the deno binary installed on the system (does not download deno).
• Specifying a specific version of Deno via DENO_VERSION env var is not supported.
