Cloudflare Worker deno server emulator

This is a experiment to replace wrangler preview --watch with Deno.

This idea is based on that Deno has the same api as Service Workers:

• addEventListener
• fetch
• Request
• Response
• URL
• URLSearchParams

That would be harder using Node, cause would need polyfill for all those objects.

HOW TO

Create a entry file entry.deno.ts that imports deno-server followed by Cloudflare Worker entry file.

import "server.deno.js"
import "./entry.worker.ts"

And run using denon to watch for file changes:

denon run --allow-net entry.deno.ts

TODO

• Configure PORT
• bin script to run against entry.worker.ts
• Make typescript version work
