# Sessions

HTTP sessions provide a way to store information about the user across multiple requests.

# Usage

As Danet uses Oak under the hood, you can use oak_sessions package.

Then, apply the oak_sessions middleware as global middleware (for example, in your bootstrap.ts file).

import { Session } from 'https://deno.land/x/oak_sessions@v4.0.5/mod.ts';

const app = new DanetApplication();
app.addGlobalMiddlewares(
  Session.initMiddleware(),
);

Notice

The default server-side session storage is purposely not designed for a production environment. It is meant for debugging and developing. Read more in the official repository.

# With cookies

Oak_session use Stores to store session data in Cookies, Sqlite, Mongodb or Postgres. The simpliest way to handle sessions is with cookies using CookieStore:

import {
  CookieStore,
  Session,
} from 'https://deno.land/x/oak_sessions@v4.0.5/mod.ts';

const app = new DanetApplication();
app.addGlobalMiddlewares(
  Session.initMiddleware(
    new CookieStore(Deno.env.get('COOKIE_SECRET_KEY') as string),
  ) as MiddlewareFunction,
);

# Session decorator

You can access the session in your routes using @Session decorator. oak_session's Session is basically a map, so we use the Map type.

import { Session,
} from 'https://deno.land/x/Danet/mod.ts';

@Get()
findAll(@Session() session: Map<unknown, unknown>) {
  const visits = session.get('visits');
  session.set('visits', visits ? visits + 1 : 1);
}
