Serving Static Files

Serving static files by registering a route

#include <stdio.h>
#include <stdlib.h>

#include "kraken.h"

#define PORT 8000
#define BACKLOG 10

char *index_handler(http_req_t *req, http_res_t *res)
{
    return res_render_static_file("./react/react.html");
}

int main()
{
    http_server_t *server = http_server_init(PORT, BACKLOG);

    register_route(server, "/", index_handler);

    http_server_listen(server);
    http_server_free(server);
}

If you have a template that you want to serve for a path, you can use the res_render_static_file procedure. It takes the path to your template file as an argument.

Serving static files from a directory

#include <stdio.h>
#include <stdlib.h>

#include "kraken.h"

#define PORT 8000
#define BACKLOG 10

int main()
{
    http_server_t *server = http_server_init(PORT, BACKLOG);

    register_static(server, "public");

    http_server_listen(server);
    http_server_free(server);

}

If you want to serve some static files from your machine such as HTML, CSS, or JavaScript files, you can register a static directory to the server. Kraken will automatically serve all of the files in this directory. The files will be accessible using the relative path and the file name with extension from the registered directory.

For example, in the above block of code, we are registering "public" as a static directory. Suppose our "public" folder looks like this:

public/

.
├── band.html
├── catering.html
├── coming-soon.html
├── css
│   └── style.css
├── images
│   ├── burger.jpg
│   ├── cta.png
│   └── leaf.avif
├── js
│   └── index.js
├── parallex.html
└── test.html

The file called "test.html" can be accessed by going to "/test.html" in the browser, while the image called "burger.jpg" will be at "/images/burger.jpg".
