Authentication Overview

Velox TS ships with two authentication strategies — JWT for stateless APIs and sessions for server-rendered apps — plus guards, policies, rate limiting, and password hashing. Choose one strategy or combine them depending on your deployment model.

Quick Comparison

Feature	JWT	Sessions
Storage	Client (token)	Server (store)
Scalability	Stateless	Requires shared store
Revocation	Difficult	Easy
Use case	APIs, mobile	Web apps, SSR

JWT Authentication

Token-based, stateless authentication with access/refresh token pairs:

import { jwtManager, authPlugin, authenticated } from '@veloxts/auth';

// Configure JWT with access and refresh tokens
const jwt = jwtManager({
  secret: process.env.JWT_SECRET!,
  refreshSecret: process.env.JWT_REFRESH_SECRET!,
  accessTokenExpiry: '15m',
  refreshTokenExpiry: '7d',
});

await app.register(authPlugin, { jwt });

// Protect procedures with guards
getProfile: procedure()
  .guard(authenticated)
  .query(({ ctx }) => ctx.user),

Session Authentication

Cookie-based, server-side sessions with secure defaults:

import { sessionMiddleware, inMemorySessionStore } from '@veloxts/auth';

const session = sessionMiddleware({
  secret: process.env.SESSION_SECRET!,  // 32+ chars
  store: inMemorySessionStore(),        // Use Redis in production
  cookie: {
    secure: true,
    httpOnly: true,
    sameSite: 'lax',
  },
  userLoader: async (userId) => db.user.findUnique({ where: { id: userId } }),
});

// Protect procedures
getProfile: procedure()
  .use(session.required())
  .query(({ ctx }) => ctx.user),

Guards

Protect procedures with authorization checks:

import { authenticated, hasRole, hasPermission } from '@veloxts/auth';

// Must be logged in
.guard(authenticated)

// Must have specific role
.guard(hasRole('admin'))

// Must have permission
.guard(hasPermission('users:write'))

// Chain multiple guards
.guard(authenticated)
.guard(hasRole('editor'))

Guards narrow ctx.user type - after authenticated, ctx.user is guaranteed to exist.

Authentication Adapters

Integrate third-party authentication providers like Clerk, Auth0, or Better Auth:

import { createClerkAdapter } from '@veloxts/auth/adapters';
import { createAuthAdapterPlugin } from '@veloxts/auth';

const adapter = createClerkAdapter({
  name: 'clerk',
  clerk: createClerkClient({ secretKey: process.env.CLERK_SECRET_KEY! }),
});

const authPlugin = createAuthAdapterPlugin({ adapter, config: adapter.config });
app.register(authPlugin);
