Training program

Module 1Advanced Associations: Model Complex Relationships (Sequelize Tools, ER Diagrams, E-commerce Cases)

Dive into many-to-many and polymorphic associations, create connected models through practical exercises on a real e-commerce project, configure belongsToMany with custom through tables, generate automated ER diagrams, test optimized joins to avoid N+1 queries, leave with solid and performant relational schemas.

Module 2Migrations and Seeders: Structure Evolving Databases (Sequelize CLI, Umzug, Fixtures)

Master complex up/down migrations with Sequelize CLI and Umzug, implement seeders for massive test data, migrate existing schemas without downtime using blue-green, practice on banking cases with ACID constraints, generate automated fixtures, validate integrity via rollback tests, boost your DevOps workflow today.

Module 3Hooks, Validations, and Scopes: Secure and Filter Data (Lifecycles, Joi, Query Scopes)

Configure before/after hooks for automated audits, integrate Joi validations with Sequelize, create dynamic scopes for admin dashboards, apply to a real REST API with user roles, test lifecycle triggers via Mocha, optimize filters for ultra-fast queries, turn your models into secure and flexible fortresses.

Module 4Transactions and Performance: Scale Critical Queries (bulkCreate, Indexes, Caching)

Manage nested transactions for secure payments, optimize bulk operations and composite indexes, integrate Redis caching for hot queries, profile slowdowns with explain/analyze, refactor a 10k-entry backlog in 2s, practice advanced eager/lazy loading, achieve production-ready performance in a flash.

Module 5Integration, Testing, and Deployment: Production Ready (Jest, Docker, CI/CD Sequelize)

Integrate Sequelize with Express using JWT auth middleware, test end-to-end with Jest/Supertest, containerize with Docker Compose, deploy to Heroku/AWS via GitHub Actions CI/CD, monitor logs and errors with Sentry, finalize a complete MVP deployed, leave certified with a pro stack and evolutionary roadmap.
