GitHub - grant/functions-framework-deno: An experimental Functions Framework for Deno (original) (raw)

Deno Functions Framework

WARNING: WIP

A lightweight, open source FaaS (Function as a Service) framework for Deno.

The framework allows you to go from:

/**

• Send "Hello, World!"
• @param request The Deno request https://deno.land/std@0.74.0/http/server.ts */ export default async (request) => { request.respond({ status: 200, body: 'Hello, World!', }); };

To:

curl http://my-url

Output: Hello, World!

All without needing to worry about writing an HTTP server or complicated request handling logic.

Features

• Spin up a local development server for quick testing
• Invoke a function in response to a request
• Automatically unmarshal events conforming to theCloudEvents spec
• Portable between serverless platforms

Installation

There's no installation step for this library. It's Deno.

Quickstart

Assumes you have Deno installed

1. Create an main.ts file with the following contents:
   export default async (request) => {
   request.respond({
   status: 200,
   body: 'Hello, World!',
   });
   };
2. Start the local server:
   deno run --allow-net --allow-read --allow-env main.ts
3. Send requests to this function using curl from another terminal window:
   curl localhost:8080
   Output: Hello, World!

Run in Container

You can also run this server in a container:

docker build -t app . && docker run -it --init -p 8080:8080 app

Deploy to Cloud Run

gcloud beta run deploy deno-ff
--source .
--allow-unauthenticated
