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@v0.4.0/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@v0.4.0/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.

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@v0.5.0/agent.ts";
const agent = createAgent("http://127.0.0.1:8700");
const { status, body } = await agent.send("/get?deno=land");

POST

import { createAgent } from "https://denopkg.com/keroxp/servest@v0.5.0/agent.ts";
const { status, headers, body } = await agent.send("/post", {
  method: "POST",
  headers: new Headers({
    "Content-Type": "text/plain"
  }),
  body: new TextEncoder().encode("deno=land")
});
