servest

🌾A progressive http server / router for deno🌾

Usage

Serve API

serve API is compatible with deno_std@v0.3.2 but has different implementation. Some progressive features for HTTP/1.1 server are implemented.

Support Keep-Alive connection
Support trailer headers
Support keep-alive timeout and read timeout
serve is cancellable by cancel promise
Fully interface based type definition

import { serve } from "https://denopkg.com/keroxp/servest@v0.7.0/server.ts";
async function main() {
  for await (const req of serve(`0.0.0.0:8899`)) {
    await req.respond({
      status: 200,
      headers: new Headers({
        "Content-Type": "text/plain"
      }),
      body: new TextEncoder().encode("hello")
    });
  }
}
main();

Router API

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

import { createRouter } from "https://denopkg.com/keroxp/servest@v0.7.0/router.ts";

const router = createRouter();
router.handle("/", async req => {
  await req.respond({
    status: 200,
    headers: new Headers({
      "content-type": "text/plain"
    }),
    body: new TextEncoder().encode("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: new TextEncoder().encode(JSON.stringify({ id }))
  });
});
router.listen("127.0.0.1:8898");

Agent API

Agent API is basic HTTP agent. It manages persistent connection to 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 host.

NOTE: Currently TLS (HTTPS) agent is not supported as Deno doesn’t.

Use fetch for https request.

GET

import { createAgent } from "https://denopkg.com/keroxp/servest@v0.7.0/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@v0.7.0/agent.ts";
const { status, headers, body } = await agent.send({
  path: "/post",
  method: "POST",
  headers: new Headers({
    "Content-Type": "text/plain"
  }),
  body: new TextEncoder().encode("deno=land")
});
