zelda

A short and sweet package for native Zig HTTP(s) requests.

Zelda uses hzzp and zig-libressl to provide a simple interface for HTTP 1.1 interactions. There is a lot that goes into retrieving data from a remote server, but sometimes you don't want to spend hours mulling over the details, especially for projects where the transport is only a portion of the story of the larger program.

Capabilities

• HTTP/1.1
• TLS 1.1, TLS 1.2, TLS 1.3
• Simple One-Shot interface for raw bytes & JSON encoded data

Linking

const zelda = @import("path/to/zelda/build.zig");

pub fn build(b: *std.build.Builder) !void {
    const exe = ...
    try zelda.link(b, exe, target, mode, use_system_libressl);
}

Example

/// Extracted from `examples/whats_my_ip/src/main.zig`
const std = @import("std");
const zelda = @import("zelda");

const IPResponse = struct {
    ip: []const u8,
};

pub fn main() anyerror!void {
    var arena = std.heap.ArenaAllocator.init(std.heap.c_allocator);
    defer arena.deinit();

    try printIPFromRaw(arena.allocator());
    try printIPFromJson(arena.allocator());
}

pub fn printIPFromJson(allocator: std.mem.Allocator) !void {
    const response = try zelda.getAndParseResponse(IPResponse, .{ .allocator = allocator }, allocator, "https://api64.ipify.org/?format=json");
    defer std.json.parseFree(IPResponse, response, .{ .allocator = allocator });

    var stdout = std.io.getStdOut().writer();

    try stdout.print("My ip is {s}\n", .{response.ip});
}

pub fn printIPFromRaw(allocator: std.mem.Allocator) !void {
    var response = try zelda.get(allocator, "http://api64.ipify.org/");
    defer response.deinit();

    var stdout = std.io.getStdOut().writer();

    if (response.body) |body|
        try stdout.print("My ip is {s}\n", .{response.body})
    else
        try stdout.writeAll("Failed to receive body from ipify\n");
}
