Basic Html implementation of hello world:

use rohanasan::{
    rohanasan, send_http_response, serve, Request, DEFAULT_HTML_HEADER,

fn handle(req: Request) -> String {
    send_http_response(DEFAULT_HTML_HEADER, "<h1>Hello!</h1>", req)

fn main() {
    rohanasan! {
        serve(8080, handle)

How to use in your project?

  • Open terminal inside the parent folder where you would like to create the folder of your project
  • Run:
cargo install rohanasanpm
rohanasanpm new my_proj
  • cd into my_proj
  • cargo run to run your project.
  • Go to: localhost:8080.

  • Can serve a folder named static at /static
  • Can send files as http response
  • Can give you the path, method and protocol


  • Add feature to change the directory path of the public folder ☑️ Done!!!!
  • Asynchronous file request handling ☑️ Done!!!!
  • Add feature to give the user an option to add index.html to static folder ☑️ Done!!!!
  • Add feature of request.post_request()
  • Add feature to... currently it's just a pre alpha release I have to add a lot of features right now!



  • Hello world (Html File):

Basic Html implementation of hello world:

use rohanasan::{
    rohanasan, send_file, serve, Request, DEFAULT_HTML_HEADER,
fn handle(req: Request) -> String {
    send_file(DEFAULT_HTML_HEADER, "./html/index.html", req)

fn main() {
    rohanasan! {
        serve(8080, handle)

Points to remember:

  • There is no need to import tokio for using rohanasan macro.
  • By default, rohanasan serves any folder named static present in the same directory where you are running the server.
