Sour

Sessions for Deno Fresh with the following stores:

PostgreSQL
MySQL
Redis
Cookie
Memory

Usage

Create an _middleware.ts file in the root of your project with:

import { MiddlewareHandlerContext } from "$fresh/server.ts";
import { sql } from "./db.ts";

const store = new Postgres(sql);

import { middleware, Postgres } from "https://deno.land/x/sour/mod.ts";

export const handler = [
  (request: Request, context: MiddlewareHandlerContext) =>
    middleware(request, context, {
      store: store,
      // Other options (see SessionOptions.ts)
    }),
];

After this you can add access and modify the session in your handlers, like:

import { WithSession } from "https://deno.land/x/sour/types.ts";

export const hander: Handlers<Data, WithSession> = {
  GET(_request, context) {
    const { session } = context.state;

    // Get a value...
    session.get("user_id");

    // Set a value...
    session.set("user_id", 973891); 

    // Check if session has value...
    session.has("user_id");

    // Flash a value to the session, which will get deleted when it is accessed...
    session.flash("error", "Username is required");

    // Will delete the session...
    session.delete();

    return context.render!();
  },
};

Memory

This is the most simple store, sessions are gone after you restart the application.

const store = new Memory();

PostgreSQL

This store uses the postgresjs library to execute its queries.

import { sql } from "./db.ts";
const store = new Postgres(sql);

Don’t forget too apply the following query to your database:

create table if not exists sessions (id varchar not
null primary key, data varchar)

Redis

TODO

MySQL

TODO

Use the middlewareCookie instead of middleware.
