Denzo

Well designed web framework for Deno. similar to Fastify. Uses Deno native http server. (which is unstable right now)

Hello world

app.ts

import {
  Denzo,
  listenAndServe,
  printRoutes,
} from "https://deno.land/x/denzo/mod.ts";

const app = new Denzo();

interface RouteTypes {
  Response: {
    hello: string;
  };
}

app.route<RouteTypes>({
  method: "GET",
  url: "/hi",
  handler() {
    return { hello: "world!" };
  },
});

listenAndServe(3000, app);
printRoutes(app);

console.log("listening on port 3000");

deno run --allow-net --unstable app.ts

Goals

Well and Reliable design: Denzo follows Fastify design which benefit large projects.
Fast: Denzo uses brand new Deno native http server which is faster and better for http/2 protocol.
First-Class validation: Like Fastify, Denzo support JSON schemes (also fluent-json-schema).
Safe: Plugins are limited to their scope, unless you grant access.

Differences with Fastify

Denzo is inspired by Fastify, but it doesn’t mean it’s a Fastify port for Deno. There’s some differences that we prefer:

No callback support

Callbacks are fast, but supporting callbacks and promises together is troublesome. so you should always use async function or return a Promise for your async code.

Keys instead of decorators

Fastify decorators design is not Typescript friendly, You can use our Keys design to safely pass data between hooks. see examples/keys.ts.
