Zig Networking — TCP, UDP, and HTTP Clients

DodaTech Updated 2026-06-29 1 min read

In this tutorial, you will learn about Zig Networking. We cover key concepts, practical examples, and best practices to help you master this topic.

Zig provides low-level networking through the standard library with zero-cost abstractions.

const std = @import("std");

pub fn main() !void {
    // TCP client
    const addr = try std.net.Address.resolveIp("127.0.0.1", 8080);
    const stream = try std.net.tcpConnectToAddress(addr);
    defer stream.close();

    // Send data
    try stream.writeAll("GET / HTTP/1.0

");

    // Read response
    var buf: [4096]u8 = undefined;
    const n = try stream.read(&buf);
    std.debug.print("{s}", .{buf[0..n]});
}
