Remix Adapter

Remix Adapter

The Remix adapter provides helper functions for using @loewen-digital/fullstack in Remix loaders and actions. Because Remix already uses Web Standard Request and Response objects, integration is straightforward.

Import

import { getUser, requireUser } from '@loewen-digital/fullstack/adapters/remix'

Setup

1. Create your stack

app/lib/stack.server.ts

import { createDb } from '@loewen-digital/fullstack/db'
import { createAuth } from '@loewen-digital/fullstack/auth'

export const db = createDb({ driver: 'sqlite', url: './app.db' })

export const auth = createAuth({
  db,
  session: { driver: 'cookie', secret: process.env.SESSION_SECRET! },
})

2. Create adapter helpers

app/lib/auth.server.ts

import { getUser, requireUser } from '@loewen-digital/fullstack/adapters/remix'
import { auth } from './stack.server.js'

export const getCurrentUser = getUser(auth)
export const requireAuth = requireUser(auth, '/login')

Using in loaders

app/routes/dashboard.tsx

import { json, type LoaderFunctionArgs } from '@remix-run/node'
import { requireAuth } from '~/lib/auth.server'

export async function loader({ request }: LoaderFunctionArgs) {
  const user = await requireAuth(request)
  // Redirects to /login if not authenticated
  return json({ user })
}

Login action

app/routes/login.tsx

import { json, redirect, type ActionFunctionArgs } from '@remix-run/node'
import { validate } from '@loewen-digital/fullstack/validation'
import { auth } from '~/lib/stack.server'

export async function action({ request }: ActionFunctionArgs) {
  const data = Object.fromEntries(await request.formData())

  const result = validate(data, {
    email: ['required', 'email'],
    password: ['required'],
  })

  if (!result.passes) {
    return json({ errors: result.errors }, { status: 422 })
  }

  const user = await auth.attempt(result.data)

  if (!user) {
    return json({ error: 'Invalid credentials' }, { status: 401 })
  }

  const response = redirect('/dashboard')
  await auth.login(user, response)
  return response
}

Logout action

export async function action({ request }: ActionFunctionArgs) {
  return auth.logout(request)
  // Returns a redirect Response that clears the session
}

Notes

• Remix already uses Request and Response — no conversion layer is needed
• The adapter helpers are thin wrappers that call auth.user(request) under the hood
• All @loewen-digital/fullstack modules work directly with Remix’s native Request objects
