When you finish, you can

  • Design a backend from requirements
  • Build it with the ZudoJS CLI and packages
  • Test, secure, document, deploy and monitor it
  • Reason about its architecture and how it scales

You build: A production-grade SaaS platform

MODULE 1

Real-world use cases

  1. 1Use case: a REST API for users, products and ordersBuild Oja Market's public API from a product brief: resources and status codes, schemas, JWT access, keyset pagination, OpenAPI and contract tests.60 min
  2. 2Use case: an authentication platformBuild Sabi School's account platform: registration, sessions, JWT rotation, password reset links, roles and sign-in with an OAuth provider, all tested.60 min
  3. 3Use case: a payment systemBuild Oja Market's card payments: idempotent requests, a gateway adapter with timeouts and retries, an outbox, events, a notification queue, and failure tests.60 min
  4. 4Use case: a multi-tenant SaaSBuild InvoiceHub, where many businesses share one app and one database, and prove with tests that one organization can never read another's data.60 min
  5. 5Use case: background processingMove invoice e-mails out of the request: a durable job ledger, a queue with retries, scheduled reminders, correlation ids and recovery from crashed workers.60 min
  6. 6Use case: a microservice platformSplit Oja Market into six services that call each other over RPC, announce events through an outbox, retry through queues, and share one trace per request.60 min

MODULE 2

Capstone

  1. 7A whole project through the CLIBuild a hall-booking API from zudojs create to a Docker image, generating each layer with the CLI and writing the business rules and tests the generator can't.70 min
