The official starter template for building applications on the Internet Development Studio Company API. Provides working implementations of authentication, payments, and user management — ready to clone and build on.

• Authentication — Email/password login and account creation, OAuth (Google, Apple, Bluesky), session management via cookies, password recovery
• Payments — Stripe subscription tiers (Free, Professional, Co-working, Partner), payment method management, direct charges
• File Uploads — S3 and Google Cloud Storage via presigned URLs (15MB max)
• Content — Documents and posts/threads CRUD operations
• UI System — Themed component library (5 themes), modal system, form elements, typography, SVG icons
• Server-Side Rendering — getServerSideProps with session validation on every page load

Requires Node.js >= 18.

git clone https://github.com/internet-development/nextjs-intdev-services-auth-payments.git
cd nextjs-intdev-services-auth-payments
npm install

Create a .env file:

API_AES_KEY=xxxxx
API_IV_KEY=xxxxx

These keys enable OAuth and password recovery. Contact the INTDEV team for the correct values. Email/password authentication works without them.

npm run dev

Open http://localhost:10000.

This is a frontend-only application. All data persists on the backend API at https://api.internet.dev (source). The template communicates via HTTP requests with X-API-KEY headers and manages sessions through browser cookies.

To enable OAuth for your deployment, set OAUTH_REDIRECT_SIGNATURE in common/constants.ts and submit a PR to the APIs repository to register your redirect URL.
