Axum Database Sessions

`axum_database_sessions` provide's a Session management middleware that stores all session data within a MemoryStore internally. It can also save data to an optional persistent database.

• Cookies only Store a Generated Session UUID and a Storable Boolean.
• Uses a DatabasePool Trait so you can implement your own Sub Storage Layer.
• Convenient API for Session no need to mark as Read or Write making Usage Easier.
• Uses dashmap for internal memory lookup and storage to achieve high throughput.
• Uses Serdes for Data Serialization so it can store any Serdes supported type's into the Sessions data.
• Supports Redis and SQLx optional Databases out of the Box.

Example

use sqlx::{ConnectOptions, postgres::{PgPoolOptions, PgConnectOptions}};
use std::net::SocketAddr;
use axum_database_sessions::{Session, SessionPgPool, SessionConfig, SessionStore, SessionLayer};
use axum::{
    Router,
    routing::get,
};

#[tokio::main]
async fn main() {

    let poll = connect_to_database().await.unwrap();

    //This Defaults as normal Cookies.
    //To enable Private cookies for integrity, and authenticity please check the next Example.
    let session_config = SessionConfig::default()
        .with_table_name("test_table");

    let session_store = SessionStore::<SessionPgPool>::new(Some(poll.clone().into()), session_config);

    //Create the Database table for storing our Session Data.
    session_store.initiate().await.unwrap();

    // build our application with some routes
    let app = Router::new()
        .route("/greet", get(greet))
        .layer(SessionLayer::new(session_store));

    // run it
    let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
    tracing::debug!("listening on {}", addr);
    axum::Server::bind(&addr)
        .serve(app.into_make_service())
        .await
        .unwrap();
}

async fn greet(session: Session<SessionPgPool>) -> String {
    let mut count: usize = session.get("count").unwrap_or(0);

    count += 1;
    session.set("count", count);

    count.to_string()
}

async fn connect_to_database() -> anyhow::Result<sqlx::Pool<sqlx::Postgres>> {
    // ...
    unimplemented!()
}

To enable private cookies for confidentiality, integrity, and authenticity. When a Key is set it will automatically set the Cookie into an encypted Private cookie which both protects the cookies data from prying eye's it also ensures the authenticity of the cookie.

Example

use sqlx::{ConnectOptions, postgres::{PgPoolOptions, PgConnectOptions}};
use std::net::SocketAddr;
use axum_database_sessions::{Session, SessionPgPool, SessionConfig, SessionStore, SessionLayer, SessionMode, Key};
use axum::{
    Router,
    routing::get,
};

#[tokio::main]
async fn main() {
    let session_config = SessionConfig::default()
        .with_table_name("test_table")
        // 'Key::generate()' will generate a new key each restart of the server.
        // If you want it to be more permanent then generate and set it to a config file.
        // If with_key() is used it will set all cookies as private, which guarantees integrity, and authenticity.
        .with_key(Key::generate());

    let session_store = SessionStore::<SessionPgPool>::new(None, session_config);
    session_store.initiate().await.unwrap();

    // build our application with some routes
    let app = Router::new()
        .route("/greet", get(greet))
        .layer(SessionLayer::new(session_store));

    // run it
    let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
    tracing::debug!("listening on {}", addr);
    axum::Server::bind(&addr)
        .serve(app.into_make_service())
        .await
        .unwrap();
}

To use axum_database_sessions in non_persistant mode Set the client to None and import SessionNullPool. SessionNullPool is always loaded and can be used where you do not want to include any database within the build.

Example

use sqlx::{ConnectOptions, postgres::{PgPoolOptions, PgConnectOptions}};
use std::net::SocketAddr;
use axum_database_sessions::{Session, SessionNullPool, SessionConfig, SessionStore, SessionLayer};
use axum::{
    Router,
    routing::get,
};

#[tokio::main]
async fn main() {
    let session_config = SessionConfig::default()
        .with_table_name("test_table");

    let session_store = SessionStore::<SessionNullPool>::new(None, session_config);

    // build our application with some routes
    let app = Router::new()
        .route("/greet", get(greet))
        .layer(SessionLayer::new(session_store));

    // run it
    let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
    tracing::debug!("listening on {}", addr);
    axum::Server::bind(&addr)
        .serve(app.into_make_service())
        .await
        .unwrap();
}

async fn greet(session: Session<SessionNullPool>) -> String {
    let mut count: usize = session.get("count").unwrap_or(0);

    count += 1;
    session.set("count", count);

    count.to_string()
}

To use axum_database_sessions with session mode set as Storable.

Example

use sqlx::{ConnectOptions, postgres::{PgPoolOptions, PgConnectOptions}};
use std::net::SocketAddr;
use axum_database_sessions::{Session, SessionPgPool, SessionConfig, SessionStore, SessionLayer, SessionMode};
use axum::{
    Router,
    routing::get,
};

#[tokio::main]
async fn main() {
    let session_config = SessionConfig::default()
        .with_table_name("test_table").with_mode(SessionMode::Storable);

    let session_store = SessionStore::<SessionPgPool>::new(None, session_config);
    session_store.initiate().await.unwrap();

    // build our application with some routes
    let app = Router::new()
        .route("/greet", get(greet))
        .layer(SessionLayer::new(session_store));

    // run it
    let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
    tracing::debug!("listening on {}", addr);
    axum::Server::bind(&addr)
        .serve(app.into_make_service())
        .await
        .unwrap();
}

//No need to set the sessions accepted or not with gdpr mode disabled
async fn greet(session: Session<SessionPgPool>) -> String {
    let mut count: usize = session.get("count").unwrap_or(0);

    // Allow the Session data to be keep in memory and the database for the lifetime.
    session.set_store(true);
    count += 1;
    session.set("count", count);

    count.to_string()
}
