ohkami - [狼] wolf in Japanese - is declarative web framework for nightly Rust.
tokio
, async-std
(and more in future)dependencies
:```toml
tokio
runtime.async-std
instead.[dependencies] ohkami = { version = "0.9.0", features = ["rt_tokio"] } tokio = { version = "1", fetures = ["full"] } ``` (And check if your Rust toolchains are nightly ones)
```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), "/:name".GET(hello), ).howl(3000).await } ```
```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 params / query: GetUserQuery, / <-- 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, req: 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
async fn main() { Ohkami::with((appendserver))( "/" .GET(root), "/hc".GET(healthcheck), "/api/users". GET(getusers). POST(createuser), ).howl(":8080").await }
fn append_server(c: &mut Context) { c.headers .Server("ohkami"); } ```
```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
} ```
Use .map_err(|e| c. /* error_method */ )?
:
```rust async fn handler1(c: Context) -> Response { makeresult() .maperr(|e| c.InternalServerError())?; }
async fn handler2(c: Context) -> Response {
let user = generatedummyuser()
.map_err(|e| c.InternalServerError()
.text("in generate_dummy_user
"))?;
}
```
