ohkami - [狼] wolf in Japanese - is declarative web framework for Rust.
tokio
, async-std
(and more in future)dependencies
:```toml
tokio
runtime.async-std
instead by feature "rt_async-std".[dependencies] ohkami = { version = "0.9.3", features = ["rt_tokio"] } tokio = { version = "1", features = ["full"] } ```
```rust use ohkami::prelude::*;
async fn health_check(c: Context) -> Response { c.NoContent() }
async fn hello(c: Context, name: String) -> Response { c.OK().text(format!("Hello, {name}!")) }
async fn main() { Ohkami::new(( "/hc". GET(health_check), "/hello/:name". GET(hello), )).howl(3000).await } ```
sh
$ cargo run
sh
$ curl http://localhost:3000/hc
$ curl http://localhost:3000/hello/your_name
Hello, your_name!
```rust use ohkami::prelude::*; use ohkami::utils::Query;
async fn main() { Ohkami::new(( "/api/users/:id". GET(getuser). PATCH(updateuser) )).howl("localhost:5000").await }
async fn get_user(c: Context, id: usize /* <-- path param */ ) -> Response {
// ...
c.OK().json(found_user)
}
struct UpdateUserQuery {
q: Option
async fn update_user(c: Context, id: usize, /* <-- path param / query: UpdateUserQuery, / <-- query params */ ) -> Response {
// ...
c.NoContent()
}
``
Use tuple like
(verion, id): (u8, usize),` for multiple path params.
```rust use ohkami::{prelude::*, utils::Payload};
struct CreateUserRequest { name: String, password: String, }
async fn create_user(c: Context, body: CreateUserRequest ) -> Response {
// ...
c.NoContent()
}
struct LoginInput { name: String, password: String, }
struct Credential { token: String, }
async fn post_login(c: Context, input: LoginInput ) -> Response {
// ...
let token = // ...
c.OK().json(Credential { token })
} ```
ohkami's middlewares are called "fangs".
```rust use ohkami::prelude::*;
async fn main() { Ohkami::with((AppendHeaders, Log), ( "/" .GET(root), "/hc".GET(healthcheck), "/api/users". GET(getusers). POST(create_user), )).howl(":8080").await }
struct AppendHeaders; impl IntoFang for AppendHeaders { fn bite(self) -> Fang { Fang::new(|c: &mut Context, req: Request| { c.headers .Server("ohkami"); req }) } }
struct Log;
impl IntoFang for Log {
fn bite(self) -> Fang {
Fang::new(|res: Response| {
println!("{res:?}");
res
})
}
}
``
Fang::new` schema :
Fn(Response) -> Response
Fn(&mut Context, Request) -> Request
, or _ -> Result<Request, Response>
for early returning error response```rust
async fn main() { // ...
let users_ohkami = Ohkami::new((
"/".
POST(create_user),
"/:id".
GET(get_user).
PATCH(update_user).
DELETE(delete_user),
));
Ohkami::new((
"/hc" .GET(health_check),
"/api/users".By(users_ohkami), // <-- nest by `By`
)).howl(5000).await
} ```
