nhttp@0.0.3

NHttp

Just native HTTP/2 micro framework for Deno. so hot 🚀

Note: Deno native HTTP/2 Hyper need Deno version 1.9.0 or higher.

Features

No third party modules and no std/lib by default.
Support middleware.
Support sub router.

Installation

deno.land

import { NHttp } from "https://deno.land/x/nhttp@0.0.3/mod.ts";

nest.land

// will soon
// import { NHttp } from "https://x.nest.land/nhttp@0.0.3/mod.ts";

Usage

import { NHttp } from "https://deno.land/x/nhttp@0.0.3/mod.ts";

const app = new NHttp();

app.get("/hello", (request, respondWith) => {
    respondWith(new Response("Hello"));
});

app.get("/json", (request, respondWith) => {
    // shorthand
    request.pond({ name: "john" });
});

app.listen(3000, () => {
    console.log("> Running on port 3000");
});

Note: request.pond just support string and json only. for other type please use respondWith instead.

Note: request.url is full url. use request.originalUrl instead.

Run

Note: native HTTP/2 is unstable. so just add –unstable flag.

deno run --allow-net --allow-read --unstable yourfile.ts

Listen

app.listen(3000);
// or
const callback = (err, opts) => {
    if (err) console.log(err);
    console.log("Running on server 3000");
}
app.listen(3000, callback);
// or
app.listen({ port: 3000, hostname: 'localhost' }, callback);
// or https
app.listen({ 
    port: 443,
    certFile: "./path/to/localhost.crt",
    keyFile: "./path/to/localhost.key",
}, callback);
// or http/2
app.listen({ 
    port: 443,
    certFile: "./path/to/localhost.crt",
    keyFile: "./path/to/localhost.key",
    alpnProtocols: ["h2", "http/1.1"]
}, callback);

Middleware

import { NHttp, HttpRequest, RespondWith, NextFunction } from "https://deno.land/x/nhttp@0.0.3/mod.ts";

const app = new NHttp();

const foo = (request: HttpRequest, respondWith: RespondWith, next: NextFunction) => {
    request.foo = "hello";
    next();
}

app.use(foo);

app.get("/hello", (request, respondWith) => {
    respondWith(new Response(request.foo));
});

app.listen(3000);

Router

import { NHttp, Router } from "https://deno.land/x/nhttp@0.0.3/mod.ts";

const app = new NHttp();

// user router
const userRouter = new Router();
userRouter.get("/user", (request, respondWith) => {
    respondWith(new Response("hello user"));
});

// item router
const itemRouter = new Router();
itemRouter.get("/item", (request, respondWith) => {
    respondWith(new Response("hello item"));
});

// register the router
app.use([userRouter, itemRouter]);
// or with prefix
// app.use('/api', [userRouter, itemRouter]);

app.listen(3000);

Request

Just Web API Request with add more some object like :

pond: (body?: string | json | undefined, opts?: { status: number; headers: Headers });
originalUrl: string;
params: object;
path: string;
query: object;
search: string | null;
parsedBody: object | undefined;
file: object | undefined;
//   more

Handle Body and Upload

import { NHttp, jsonBody, urlencodedBody, multipartBody } from "https://deno.land/x/nhttp@0.0.3/mod.ts";
const app = new NHttp();

app.use(jsonBody(), urlencodedBody());

app.post("/hello", async (request, respondWith) => {
    console.log(request.parsedBody);
    respondWith(new Response("body was parsed"));
});

// handle upload multipart/form-data
app.post("/upload", multipartBody({ fileKey: "image" }), async (request, respondWith) => {
    if (!request.file?.image) {
      throw new Error("Image is required");
    }
    let file = request.file.image as File;
    console.log(file.name);
    console.log(request.parsedBody);

    // convert to array buffer
    let arrBuf = await file.arrayBuffer();

    // save file
    await Deno.writeFile("./" + file.name, new Uint8Array(arrBuf));
    respondWith(new Response("Success upload file"));
});
app.listen(3000);

For nested object in urlencoded and multipart, you can use qs :

import { NHttp, urlencodedBody, multipartBody } from "https://deno.land/x/nhttp@0.0.3/mod.ts";
import qs from "https://esm.sh/qs?no-check";

// application/x-www-form-urlencoded
app.use(urlencodedBody({ parse: qs.parse }));

// multipart/form-data
app.post("/upload", multipartBody({ fileKey: "image", parse: qs.parse }), ...more);

RespondWith

Just callback Web API Response.

...
// example with status and headers
app.get("/hello", (request, respondWith) => {
    respondWith(new Response("Hello", {
        status: 200,
        headers: new Headers({
            'x-powered-by': 'nhttp'
        })
    }))
})
...

Error Handling

...
// global error handling
app.onError((error, request, respondWith) => {
    respondWith(new Response(error.message), {
        status: error.status || 500
    })
})

// global not found error handling
app.on404((request, respondWith) => {
    respondWith(new Response(`${request.originalUrl} not found`), {
        status: 404
    })
})
...
