Compression

Demonstrates Content-Encoding parsing, the httpx.decompress() API, compression middleware, and how clients advertise supported algorithms via Accept-Encoding.

Demo Program

// Iterate all supported Content-Encoding values
for (httpx.ContentEncoding.ALL) |enc| {
    std.debug.print("{s} -> .{s}\n", .{ enc.toString(), @tagName(enc) });
}

// Identity passthrough — input equals output
const decompressed = try httpx.decompress(allocator, .identity, original);

// Enable compression middleware on the server
try server.use(httpx.middleware.compression());

// Client advertises supported encodings
var req = try httpx.Request.init(allocator, .GET, "http://127.0.0.1/data");
try req.headers.set("Accept-Encoding", "gzip, deflate, zstd");

Checklist

• [x] ContentEncoding.ALL lists gzip, deflate, zstd, brotli
• [x] httpx.decompress(.identity, ...) returns input unchanged
• [x] Server accepts and applies compression middleware
• [x] Client sends Accept-Encoding header with supported algorithms
• [x] Supported algorithms print: gzip, deflate, zstd, br
