Http server for Zig

Routez

HTTP server for Zig.

Example

basic

Run with zig build basic

const std = @import("std");
const Address = std.net.Address;
usingnamespace @import("routez");
const allocator = std.heap.page_allocator;

pub const io_mode = .evented;

pub fn main() !void {
    var server = Server.init(
        allocator,
        .{},
        .{
            all("/", indexHandler),
            get("/about", aboutHandler),
            get("/about/more", aboutHandler2),
            get("/post/{post_num}/?", postHandler),
            static("./", "/static"),
            all("/counter", counterHandler),
        },
    );
    var addr = try Address.parseIp("127.0.0.1", 8080);
    try server.listen(addr);
}

fn indexHandler(req: Request, res: Response) !void {
    try res.sendFile("examples/index.html");
}

fn aboutHandler(req: Request, res: Response) !void {
    try res.write("Hello from about\n");
}

fn aboutHandler2(req: Request, res: Response) !void {
    try res.write("Hello from about2\n");
}

fn postHandler(req: Request, res: Response, args: *const struct {
    post_num: []const u8,
}) !void {
    try res.print("Hello from post, post_num is {}\n", args.post_num);
}

var counter = std.atomic.Int(usize).init(0);
fn counterHandler(req: Request, res: Response) !void {
    try res.print("Page loaded {} times\n", counter.fetchAdd(1));
}

routez's Issues

Server doesn't parse query string

Hi!

In file routez/http/parser.zig there's this code (line 24):

    if (req.path.len > 1) {
        const uri = try Uri.parse(ctx.buf[cur .. ctx.index - 1], true);
        req.path = try Uri.resolvePath(req.headers.list.allocator, uri.path);
        req.query = uri.query;
    } else {
        req.path = try req.headers.list.allocator.dupe(u8, ctx.buf[cur .. ctx.index - 1]);
    }

I don't understand why you do this test, as it will always use the else branch (req.path is initialized to "" at this point). Else brach will copy both path and query string in req.path, leaving req.query = "".

I tested removing the if / else and it jost works as expected:

    const uri = try Uri.parse(ctx.buf[cur .. ctx.index - 1], true);
    req.path = try Uri.resolvePath(req.headers.list.allocator, uri.path);
    req.query = uri.query;

Maybe I'm missing some other aspect?

Thanks!

Quiting from server has delay

Hi,

When I create a debug server and try to fire some route, for example I run the basic.zig from examples and ping http://localhost:8080/counter.

Now I want to restart my server, for example I made some changes in the code,
I close the server with ctrl+c and rerun it, then I get error error: AddressInUse

The server address becomes available and is released after some minutes of waiting, so how could I close my server immediately ?

My OS is Ubuntu 20.10

demo is down

@Vexu, the routez.vexu.eu domain is down.

`zig build basic` fails with error in build.zig

Hi,
will trying out your code :

zig build basic
./build.zig:17:9: error: no member named 'path' in struct 'std.build.Pkg'
        .path = .{ .path = "src/routez.zig" },
        ^

Since I am new to zig, I have no clue to help out debugging, but thought to report it here anyway.

When looking at this kind of error on other zig projects, it seems this is related to changes in build from 0.9 to zig version 0.10 with I am currently running.

zig version 
0.10.0-dev.3456+40babaa53

Best.

Routez on Techempower

Hi there

I am learning Zig and was wondering if i can pick up a small project like adding Routez to Techempower benchmarks.

I fully understand that Zig and Routez are very nascent right now, and performance is likely not a major area of focus. - but I think it will be interesting to know how well it currently does against established web servers.

Would it be ok with you if I were to add Routez to the techempower benchmarks?

Expose the Request struct for testing.

Hello,

Is it possible to expose the Request struct. It is necessary to make request handlers tests.

Thanks

Split HTTP and Web server implementations

Wouldn't it be better to split implementations of HTTP protocol and a Web server (routing, serving files, etc)?

Changing status_code in handler

Hei,

What would be the preferred way to change the status_code inside the route handler,
Currently, this line https://github.com/Vexu/routez/blob/master/src/routez/router.zig#L59 ,
always overwrites my custom set status.

For example in my route I would like to use res.status_code = .BadRequest;
It will still be sent as .Ok

Just commenting the above line out and setting it to .Ok here https://github.com/Vexu/routez/blob/master/src/routez/server.zig#L181, fixes the issue, am I breaking something with this ?

error: function type cannot have a name

When i run my code, it gives me this error. How i can fix it?

error: function type cannot have a name
pub const HandlerFn = fn handle(Request, Response, []const u8) callconv(.Async) anyerror!void;

routez.vexu.eu

routez.vexu.eu seems to timeout whenever I visit it,
is it normal?

Unable to spawn zig-cache/basic: FileNotFound
