NATS.c

This is the NATS C client library, packaged for Zig.

Status

This library only explicitly supports Linux, macOS, and Windows operating systems. Building for other platforms is currently untested, so your mileage may vary.

Zig Bindings

The following projects provide Zig language bindings to the NATS.c library:

• epicyclic-dev/nats-client

Usage

First, update your build.zig.zon:

# Initialize a `zig build` project if you haven't already
zig init
# replace <refname> with the version you want to use, e.g. 3.9.1
zig fetch --save git+https://github.com/allyourcodebase/nats.c.git#<refname>

You can then import nats_c in your build.zig with:

const nats_c_dep = b.dependency("nats_c", .{
    .target = target,
    .optimize = optimize,
    .@"enable-libsodium" = true, // Use libsodium for optimized implementations of some signing routines
    .@"enable-tls" = true, // enable SSL/TLS support
    .@"force-host-verify" = true, // force hostname verification for TLS connections
    .@"enable-streaming" = true, // build with support for NATS streaming extensions
});
your_exe.linkLibrary(nats_c_dep.artifact("nats_c"));

Dependencies

The NATS.c library has optional dependencies:

• libressl 3.9.2 when building with enable-tls
• protobuf-c 1.5.0 when building with enable-streaming
• libsodium stable branch when building with enable-libsodium

These dependencies are currently automatically retrieved and compiled as static libraries by the Zig build system.
