Native Auth

Implement native username/password authentication

1. In your src directory, create a hooks.server.ts file

// Import if you would like to utilize native user registration and login
import { SvaultNative } from 'svault';


// Set redirect path to your desired endpoint upon user login
const redirectPath = '/[yourPathHere]'; //ex. 'const redirectPath = '/homepage'


// Svault native handler
export const handle = SvaultNative(redirectPath);

2. Create a PostgreSQL table with the following columns:

CREATE TABLE [YOURTABLENAME] (
    username VARCHAR NOT NULL,
    password VARCHAR NOT NULL
)

3. In your routes directory, create a route called login. In your login +page.svelte, create form elements for taking in username and password inputs. Create buttons for login and register.
   • Ensure the endpoints are set to registerValidate and loginValidate
   • Create a separate button that is set to logout endpoint

// Example routes/login/+page.svelte

<form method="post">
    <input
        type="text"
        placeholder="Username"
        name="username"
        required
    />
    <input
        type="password"
        placeholder="Password"
        name="password"
        required
    />

    <button type="submit" formaction="?/registerValidate">
        Register
    </button>
    <button type="submit" formaction="?/loginValidate">
        Login
    </button>
  </form>

// To implement logout functionality, create a button or anchor tag in your page.svelte that redirects to '/logout'

<button>
    <a href="/logout">Logout</a>
</button>

4. In your .env file (create if you haven’t done so) that takes in your database URI and user table name

// Paste if using native authentication with a PostgreSQL database
PG_URI = YOURDATABASEURI
TABLE_NAME = YOURTABLENAME //ex. TABLE_NAME = users

//MAX_AGE will determine the expiration time of the user's session
MAX_AGE = Date.now() + {someNumberHere} * {someNumberHere}
// ex. Date.now() + 1000 * 60 * 60 --> session will last for 1 hour

5. After submitting the form, the user will be redirected to the endpoint of your choice.

   • Upon registering, the user will be added to the database with the username and a secure hashed password.

   • On login, the user will be authenticated through your database.

   • A browser cookie will be created as well as a session in local memory storage called “svault-auth”.

   
   • The session will have an expiration time determined in your .env file.
   • Sessions will automatically be cleaned and deleted upon expiration.
   • On logout, the user will be redirected to the home page, the cookie will be deleted from the browser, and the session will be deleted from local memory store.

And you’re good to go!
