Defining Routes

We can create our routes with these functions:

• get() for GET routes,
• post() for POST routes,
• put() for PUT routes,
• patch() for PATCH routes,
• del() for DELETE routes.

If they don’t have any middleware, they take 2 parameters: First one is the path and second one is the handler.

They must be defined in the entry point, which is the int main(void) function in the main.c file. But we must call the init_router() before we register the routes and call reset_router() in the server cleanup function to free their memory. So an example main.c file should be like this:

main.c

#include "server.h"
#include "our_handlers.h"

void destroy_app(void) {
    reset_router();
}

int main(void) {
    init_router();

    del("/delete", delete_handler);
    put("/update", update_handler);
    patch("/edit", edit_handler)
    post("/create", create_handler);
    get("/", get_handler);

    shutdown_hook(destroy_app);
    ecewo(3000);
    return 0;
}

We also can define our routes in another file and call of them in main function. Let’s make an example:

routes.c

#include "our_handlers.h"

void register_our_routes(void)
{
    del("/delete", delete_handler);
    patch("/edit", edit_handler)
    put("/update", update_handler);
    post("/create", create_handler);
    get("/", get_handler);
}

And declare this function in a header file:

routes.h

#ifndef OUR_ROUTES_H
#define OUR_ROUTES_H

void register_our_routes(void);

#endif

Let’s call it in main function:

#include "server.h"
#include "our_routes.h"

void destroy_app(void) {
    reset_router();
}

int main(void) {
    init_router();

    register_our_routes();

    shutdown_hook(destroy_app);
    ecewo(3000);
    return 0;
}

NOTE

Routes might take more than 2 parameters via use() if we use middlewares. Middlewares are explained in Middleware chapter.
