# urlrouter (WIP)

A header-only, zero-allocation, no std efficient url router in C99.

It is implemented with a [radix trie](https://en.wikipedia.org/wiki/Radix_tree) and scales well with a high number of routes.

It is inspired by the [matchit](https://lib.rs/matchit) crate in rust.

## Example

```c

#include 

#define URLROUTER_IMPLEMENTATION

#include "urlrouter.h"

typedef void (*user_cb_t)(urlparam id);

void user(urlparam id)

{

	if (id.value)

		printf("New req with id: %.*s\n", id.len, id.value);

	else

		printf("New req without id\n");

}

int main(void)

{

	urlrouter router;

	char buff[1024 * 4]; // This buffer is enough to store ~50 routes

	urlrouter_init(&router, buff, 1024 * 4);

	urlrouter_add(&router, "/user/{id}/test", user);

	urlrouter_add(&router, "/user", user);

	urlparam params[5] = {0};

	user_cb_t cb = urlrouter_find(&router, "/user/168/test", params, 5, NULL);

	if (cb)

		cb(params[0]);

	else

		printf("route not found\n");

	return 0;

}

```
