Crag-Web is a lightweight and flexible HTTP web server framework written in Rust. Inspired by the diverse routes found at climbing crags, Crag-Web allows you to define and handle various HTTP routes with ease, making it simple to build powerful web applications.
- Simple Routing: Define routes for handling HTTP requests with ease.
- Multithreading with Built-in Threadpool: Defines a built-in threadpool, with custom Worker thread amounts, to handle concurrent requests efficiently.
- Extensible: Designed to be easily extendable with custom components.
- CSRF Token Validation: Designed to safely handle POST requests by impelmenting CSRF validation.
To use Crag-Web in your Rust project, add the following dependency to your Cargo.toml:
[dependencies]
crag-web = "0.1.0"use std::net::ToSocketAddrs;
use crag_web::{server, request, response};
// get "/hello"
fn hello_handler() -> response::Response {
let body = "Hello, Crag-Web!";
let status_line = "HTTP/1.1 200 OK";
let len = body.len();
// format http response
let response = format!(
"{status_line}\r\nContent-Length: {len}\r\n\r\n{body}"
);
response::Response{ content: response.as_bytes().to_vec() }
}
// get <bad request>
fn error_404_handler() -> response::Response {
let body = "404 not found";
let status_line = "HTTP/1.1 404 Not Found";
let len = body.len();
// format http response
let response = format!(
"{status_line}\r\nContent-Length: {len}\r\n\r\n{body}"
);
response::Response{ content: response.as_bytes().to_vec() }
}
fn main() -> std::io::Result<()> {
// validate addr
let addr = "127.0.0.1:8010";
let socket_addr = match addr.to_socket_addrs() {
Ok(addr_iter) => addr_iter,
Err(_) => panic!("could not resolve socket address")
}
.next()
.unwrap();
// Create server
let pool_size = 4;
let handlers = std::collections::HashMap::new();
let app = server::Server::build(socket_addr, pool_size, handlers)
.expect("Unable to create Server")
.register_error_handler(error_404_handler)
.register_handler(request::Request::GET(String::from("/hello")), hello_handler);
// Run server
app.run();
Ok(())
}This example creates a simple web server using Crag-Web that responds with "Hello, Crag-Web!" when accessing the /hello route.
