bare-mux

A system for managing http transports in a project such as Ultraviolet and Scramjet.

Written to make the job of creating new standards for transporting http data seamless.

Implements the TompHTTP Bare client interface in a modular way.

Specifically, this is what allows proxies such as Nebula to switch HTTP transports seamlessly.

A transport is a module that implements the BareTransport interface.

export interface BareTransport {
  init: () => Promise<void>;
  ready: boolean;
  connect: (
    url: URL,
    origin: string,
    protocols: string[],
    requestHeaders: BareHeaders,
    onopen: (protocol: string) => void,
    onmessage: (data: Blob | ArrayBuffer | string) => void,
    onclose: (code: number, reason: string) => void,
    onerror: (error: string) => void,
  ) => [( (data: Blob | ArrayBuffer | string) => void, (code: number, reason: string) => void )] => void;

  request: (
    remote: URL,
    method: string,
    body: BodyInit | null,
    headers: BareHeaders,
    signal: AbortSignal | undefined
  ) => Promise<TransferrableResponse>;

  meta: () => BareMeta
}

A guide to making a transport can be found here.

Upgrading

A guide for updating from v1 to v2 can be found here.

Older bare-mux versions

Starting from v2, bare-mux uses SharedWorkers to provide stability and improve on resource usage.

If you operate using an older bare-mux, we encourage you to update.

If you're too lazy to do either of the above, you can install an outdated and unsupported version of bare-mux.

npm install @mercuryworkshop/bare-mux@1

Usage

Examples of transports include EpoxyTransport, CurlTransport, and Bare-Client.

Here is an example of using bare-mux:

/// As an end-user
import { BareMuxConnection } from "@mercuryworkshop/bare-mux";
const conn = new BareMuxConnection("/bare-mux/worker.js");
// Set Bare-Client transport
await conn.setTransport("/path/to/transport/index.mjs", ["arg1", { wisp: "wss://wisp.mercurywork.shop" }, "arg3"]);
// Epoxy Client as an example
await conn.setTransport("/epoxy/index.mjs", [{ wisp: "wss://wisp.mercurywork.shop/" }]);

/// As a proxy developer
import { BareClient } from "@mercuryworkshop/bare-mux";
const client = new BareClient();
// Fetch
const resp = await client.fetch("https://example.com");
// Create websocket
const ws = client.createWebSocket("wss://echo.websocket.events");
