FusionAuth

Integrates authentication, authorization, and user management with FusionAuth using the official TypeScript SDK and REST APIs. Covers all auth flows, token lifecycle, webhooks, and multi-tenant deployments.

Workflow

1. Audit existing setup

Read:

• .env / .env.local — look for FUSIONAUTH_URL, FUSIONAUTH_API_KEY, FUSIONAUTH_APP_ID, FUSIONAUTH_TENANT_ID
• package.json — confirm @fusionauth/typescript-client is listed
• Any existing auth files (e.g., lib/auth.ts, server/fusionauth.ts) — identify what flows are already implemented

If the SDK is not installed:

npm install @fusionauth/typescript-client
