- macro-less and type-safe APIs for intuitive and declarative code
- multi runtime support:
tokio
,async-std
,worker
(Cloudflare Workers)
- Add to
dependencies
:
# This sample uses `tokio` runtime.
# `async-std` is available by feature "rt_async-std".
[dependencies]
ohkami = { version = "0.18", features = ["rt_tokio"] }
tokio = { version = "1", features = ["full"] }
- Write your first code with Ohkami : examples/quick_start
use ohkami::prelude::*;
use ohkami::typed::status::NoContent;
async fn health_check() -> NoContent {
NoContent
}
async fn hello(name: &str) -> String {
format!("Hello, {name}!")
}
#[tokio::main]
async fn main() {
Ohkami::new((
"/healthz"
.GET(health_check),
"/hello/:name"
.GET(hello),
)).howl("localhost:3000").await
}
- Run and check the behavior :
$ cargo run
$ curl http://localhost:3000/healthz
$ curl http://localhost:3000/hello/your_name
Hello, your_name!
npm create cloudflare ./path/to/project -- --template https://github.com/kana-rus/ohkami-templates/worker
Then your project
has wrangler.toml
, package.json
and src/lib.rs
with
Cargo.toml
# ...
[dependencies]
ohkami = { version = "0.18", features = ["rt_worker"] }
worker = { version = "0.2.0" }
Local dev by npm run dev
and depoly by npm run deploy

Ohkami's request handling system is called "fangs", and middlewares are implemented on this :
use ohkami::prelude::*;
#[derive(Clone)]
struct GreetingFang;
impl FangAction for GreetingFang {
async fn fore<'a>(&'a self, req: &'a mut Request) -> Result<(), Response> {
println!("Welcomm request!: {req:?}");
Ok(())
}
async fn back<'a>(&'a self, res: &'a mut Response) {
println!("Go, response!: {res:?}");
}
}
#[tokio::main]
async fn main() {
Ohkami::with(GreetingFang, (
"/".GET(|| async {"Hello, fangs!"})
)).howl("localhost:3000").await
}
use ohkami::prelude::*;
use ohkami::typed::status::{Created, NoContent};
use ohkami::typed::Payload;
use ohkami::builtin::payload::JSON;
#[Payload(JSON/S)]
struct User {
name: String
}
async fn list_users() -> Vec<User> {
vec![
User { name: String::from("actix") },
User { name: String::from("axum") },
User { name: String::from("ohkami") },
]
}
async fn create_user() -> Created<User> {
Created(User {
name: String::from("ohkami web framework")
})
}
async fn health_check() -> NoContent {
NoContent
}
#[tokio::main]
async fn main() {
// ...
let users_ohkami = Ohkami::new((
"/"
.GET(list_users)
.POST(create_user),
));
Ohkami::new((
"/healthz"
.GET(health_check),
"/api/users"
.By(users_ohkami), // nest by `By`
)).howl("localhost:5000").await
}
use ohkami::prelude::*;
use ohkami::testing::*; // <--
fn hello_ohkami() -> Ohkami {

}
#[cfg(test)]
#[tokio::test]
async fn test_my_ohkami() {
let t = hello_ohkami().test();
let req = TestRequest::GET("/");
let res = t.oneshot(req).await;
assert_eq!(res.status(), Status::NotFound);
let req = TestRequest::GET("/hello");
let res = t.oneshot(req).await;
