• passing all autobahn tests
• handles per message deflate, including sliding window bits size negotiation
• uses zlib for message compression/decompression

Include library in you project

There is a minimal project in examples/exe which demonstrates how to use websocket client.

• add dependency to ws lib in your build.zig.zon
• link library in your build.zig

Then you can @import("ws") in src/main.zig. This example uses public echo ws server at ws://ws.vi-server.org/mirror/. Connects to websocket server, sends hello message and prints echoed reply.

Above url is taken from websocat - curl for WebSocket tool.

You can start websocat server locally with for example:

websocat -s 8080

and then connect to it by changing hostname, uri, port to:

    const hostname = "localhost";
    const uri = "ws://localhost/";
    const port = 8080;
