Cookiebox
A strongly typed cookie management crate for the Actix Web framework.
cookiebox provides a robust, type-safe, and flexible approach to managing cookies in Actix web based applications. It allows you to define, configure, and retrieve cookies with minimal boilerplate.
Features
- This crate uses biscotti under the hood which inherit most of it's features.
- Supports custom configuration settings per cookie
- Define specific types for deserializing cookie values during retrieval
- Customize data type and serialization method for each cookie.
- A Simple and type safe interface for retrieving, adding, removing cookies.
Usage
To start using the cookiebox crate in your web application you must register [CookieMiddleware] in your App.
use actix_web::{web, App, HttpServer, HttpResponse, Error};
use cookiebox::{Processor, ProcessorConfig, CookieMiddleware};
#[actix_web::main]
async fn main() -> std::io::Result<()> {
// Start by creating a `Processor` from the `ProcessorConfig`
// This decides which cookie needs to decrypted or verified.
let processor: Processor = ProcessorConfig::default().into();
HttpServer::new(move ||
App::new()
// Add cookie middleware
.wrap(CookieMiddleware::new(processor.clone()))
.default_service(web::to(|| HttpResponse::Ok())))
.bind(("127.0.0.1", 8080))?
.run()
.await
}
Now, define the desired typed cookies with custom configuration
use cookiebox::cookiebox_macros::cookie;
use cookiebox::cookies::{Cookie, CookieName, IncomingConfig, OutgoingConfig};
use cookiebox::{Attributes, SameSite};
use cookiebox::Storage;
use actix_web::{HttpRequest, FromRequest, HttpMessage, dev::Payload};
use actix_utils::future::{ready, Ready};
use serde_json::json;
// Define you cookie type struct
#[cookie(name = "__my-cookie")]
pub struct MyCookie;
// IncomingConfig give the cookie type get and get_all cookie with similar name
// You may opt out if don't want read cookie data
impl IncomingConfig for MyCookie {
// Configure the get return to any custom type
type Get = String;
}
// OutgoingConfig give the cookie type insert and remove cookie
// You may opt out if don't want insert or remove a cookie
impl OutgoingConfig for MyCookie {
// Configure the insert to any custom type
type Insert = (String, i32);
// In most cases, the default serialization should be sufficient. However, if needed,
// you can customize the way the cookie value is serialized by implementing this method.
fn serialize(values: Self::Insert) -> serde_json::Value {
json!(
format!("String: {} - i32: {}", values.0, values.1)
)
}
// Set the appropriate attribute for the cookie check `Attributes` for more details
fn attributes<'c>() -> Attributes<'c> {
Attributes::new().same_site(SameSite::Lax).http_only(false)
}
}
// Add all cookies in cookie collection
pub struct CookieCollection<'c>(Cookie<'c, MyCookie>);
//Once defined, your cookies can be accessed in request handlers by implementing `FromRequest` for a collection
//of typed cookies.
impl FromRequest for CookieCollection<'static> {
type Error = Box<dyn std::error::Error>;
type Future = Ready<Result<Self, Self::Error>>;
fn from_request(req: &HttpRequest, _payload: &mut Payload) -> Self::Future {
// fetch the storage value from request extensions and add it to all your cookies
match req.extensions().get::<Storage>() {
Some(storage) => ready(Ok(CookieCollection(Cookie::<MyCookie>::new(&storage)))),
None => ready(Err("Storage is missing".into())),
}
}
}
