servest

🌾A progressive http server / router for deno🌾

Usage

Serve API

Serve API is low-level API for handling http requests. servest has its own serving implementation based on Deno.listen(). It doesn’t depend on deno_std’s http module.

Support Keep-Alive connection
Support trailer headers
Support keep-alive timeout and read timeout
listenAndServe is cancellable by listener.close()
Fully interface based type definition

import { listenAndServe } from "https://denopkg.com/keroxp/servest/server.ts";
const listener = listenAndServe("127.0.0.1:8899", async req => {
  await req.respond({
    status: 200,
    headers: new Headers({
      "Content-Type": "text/plain"
    }),
    body: "hello"
  });
});

Router API

Router API is minimal routing system on top of listenAndServe()

import { createRouter } from "https://denopkg.com/keroxp/servest/router.ts";

const router = createRouter();
router.handle("/", async req => {
  await req.respond({
    status: 200,
    headers: new Headers({
      "content-type": "text/plain"
    }),
    body: "ok"
  });
});
router.handle(new RegExp("/foo/(?<id>.+)"), async req => {
  const { id } = req.match.groups;
  await req.respond({
    status: 200,
    headers: new Headers({
      "content-type": "application/json"
    }),
    body: JSON.stringify({ id })
  });
});
router.listen("127.0.0.1:8899");

Middleware API for Router

Router can use common http handler

import { serveStatic } from "https://denopkg.com/keroxp/servest/serve_static.ts";
// Files in ./public are served automatically (GET, HEAD)
router.use(serveStatic("./public"));

Global Error Handler for Router

// Called when unhandled error occurred while processing requests
router.handleError((e, req) => {
  console.error(e);
  req.respond({
    status: 500,
    body: "Internal Server Error"
  });
});

Agent API

Agent API is basic HTTP/HTTPS agent. It manages persistent connection to the host. Each request will be sent in serial.

fetch is enough for most cases. It is useful if you want to manage keep-alive connection to the host.

GET

import { createAgent } from "https://denopkg.com/keroxp/servest/agent.ts";
const agent = createAgent("http://127.0.0.1:8700");
const { status, body } = await agent.send({
  path: "/get?deno=land",
  method: "GET"
});

POST

import { createAgent } from "https://denopkg.com/keroxp/servest/agent.ts";
const { status, headers, body } = await agent.send({
  path: "/post",
  method: "POST",
  headers: new Headers({
    "Content-Type": "text/plain"
  }),
  body: "deno=land"
});
