File Server

HTTP Status Code and Status Text

Methods

Provides helper functions and types to work with HTTP method strings safely.

Negotiation

A set of functions which can be used to negotiate content types, encodings and languages when responding to requests.

Note: some libraries include accept charset functionality by analyzing the Accept-Charset header. This is a legacy header that clients omit and servers should ignore therefore is not provided.

Cookie maps

An alternative to cookie.ts is cookie_map.ts which provides CookieMap, SecureCookieMap, and mergeHeaders to manage request and response cookies with the familiar Map interface.

User agent handling

The UserAgent class provides user agent string parsing, allowing a user agent flag to be semantically understood.

For example to integrate the user agent provided in the header User-Agent in an http request would look like this:

import { UserAgent } from "@std/http/user_agent";

Deno.serve((req) => {
  const userAgent = new UserAgent(req.headers.get("user-agent") ?? "");
  return new Response(`Hello, ${userAgent.browser.name}
    on ${userAgent.os.name} ${userAgent.os.version}!`);
});
