CurlTransport

This is a proxy-transports transport using libcurl.js. It allows you to encrypt the traffic on your web proxy using TLS and Wisp.

Usage:

Here is a basic example of using CurlTransport. The Wisp proxy server is specified in the websocket option.

import { LibcurlClient } from "@mercuryworkshop/libcurl-transport";
let client = new LibcurlClient({ websocket: "wss://example.com/wisp/" });

// pass to proxy

You can also use the non-esm build

<script src="https://unpkg.com/@mercuryworkshop/libcurl-transport@2/dist/index.js"></script>
<script>
  let client = new LibcurlTransport.LibcurlClient({ websocket: "wss://example.com/wisp/" });
</script>

If you would like to use wsproxy instead of Wisp, set transport: "wsproxy". Wsproxy is similar to Wisp, but each TCP connection exists as a separate Websocket instead of being multiplexed.

import { LibcurlClient } from "@mercuryworkshop/libcurl-transport";
let client = new LibcurlClient({ websocket: "wss://example.com/wisp/", transport: "wsproxy" });

You can also set the max number of open connections for libcurl.js. The connections option is passed through to HTTPSession.set_connections in libcurl.js. It is an array of 3 integers, where the first is the hard limit of active connections (default 60), the second is limit for the connection cache (default 50), and the third is the max connections per host (default 6).

let client = new LibcurlClient({ websocket: "wss://example.com/wsproxy/", connections: [30, 20, 1] })
