A Http server written in Zig

ZHP

A (work in progress) Http server written in Zig.

If you have suggestions on improving the design please feel free to comment!

Features

• A zero-copy parser and aims to compete with these parser_benchmarks while still rejecting nonsense requests. It currently runs around ~1000MB/s.
• Regex url routing thanks to ctregex
• Struct based handlers where the method maps to the function name
• A builtin static file handler, error page handler, and not found page handler
• Middleware support
• Parses forms encoded with multipart/form-data
• Streaming responses
• Websockets

See how it compares in the http benchmarks done by kprotty (now very old).

It's a work in progress... feel free to contribute!

Demo

Try out the demo at https://zhp.codelv.com.

Note: If you try to benchmark the server it'll ban you, please run it locally or on your own server to do benchmarks.

To make and deploy your own app see:

• demo project
• zig buildpack

Example

See the example folder for a more detailed example.

const std = @import("std");
const web = @import("zhp");

pub const io_mode = .evented;
pub const log_level = .info;

const MainHandler = struct {
    pub fn get(self: *MainHandler, request: *web.Request, response: *web.Response) !void {
        try response.headers.put("Content-Type", "text/plain");
        try response.stream.write("Hello, World!");
    }

};

pub const routes = [_]web.Route{
    web.Route.create("home", "/", MainHandler),
};

pub const middleware = [_]web.Middleware{
    web.Middleware.create(web.middleware.LoggingMiddleware);
};

pub fn main() anyerror!void {
    var gpa = std.heap.GeneralPurposeAllocator(.{}){};
    defer std.debug.assert(!gpa.deinit());
    const allocator = &gpa.allocator;

    var app = web.Application.init(allocator, .{.debug=true});
    defer app.deinit();

    try app.listen("127.0.0.1", 9000);
    try app.start();
}
