Why this program matters

  • Without advanced TypeORM mastery, your Node.js apps risk production crashes from poorly managed relations, with 40% of bugs tied to the DB according to Stack Overflow.

  • Lose 25h/week debugging slow queries, impacting ROI by 30% on scalable projects.

  • Botched migrations cause costly downtimes (average 5k€/incident Gartner).

  • Unoptimized concurrency tanks performance; users flee to smoother rivals.

  • Avoid 3x maintenance overruns, advance from junior to expert, and boost your career with +20% salaries for TypeORM seniors.

TypeORM Advanced training objectives

  • Model complex entities with advanced many-to-many and polymorphic relationships.
  • Implement automated and custom migrations for DB evolutions without downtime.
  • Optimize TypeORM queries for x10 performance via indexing, eager/lazy loading.
  • Manage ACID transactions and concurrency with advanced QueryBuilder.
  • Integrate TypeORM into microservices architectures and scalable APIs.
  • Debug and monitor DB queries in production with advanced logging.
  • Produce reusable repositories and comprehensive unit tests.

TypeORM Advanced curriculum: 4 modules over 4 days

Module 1 : Advanced Entities: Model Complex Relationships with TypeORM (Decorators, Inheritance).

Dive into creating sophisticated entities, configure one-to-many, many-to-many, and polymorphic relationships using @OneToMany, @ManyToMany decorators, test with practical exercises on PostgreSQL, generate automated schemas, produce concrete ER diagrams for your real projects, while mastering cascades and lazy loading for optimal fluidity.

Module 2 : Advanced Migrations: Synchronize DB Schemas Without Interruption (TypeORM CLI).

Master custom up/down migrations, use TypeORM CLI for complex scripts, apply to concrete cases like refactoring legacy tables, manage massive data seeds, test rollbacks in interactive workshops, avoid downtimes in production, leave with ready-to-use templates to accelerate your deployments.

Module 3 : Optimized Queries: Boost Performance with QueryBuilder and Raw SQL.

Optimize queries via QueryBuilder, integrate subqueries, advanced joins, apply infinite pagination, measure x10 gains with profiling tools, manage eager/lazy for scalable apps, practice on large datasets, integrate Redis caching, transform your APIs into ultra-fast machines ready for high traffic.

Module 4 : Transactions, Monitoring, and TypeORM Best Practices in Microservices.

Implement distributed transactions, manage locks and isolation levels, configure logging/debug with Winston, monitor via DataDog, integrate into NestJS microservices, build custom testable repositories with Jest, conclude with a deliverable capstone project, adopt patterns for production-ready, zero-bug code.

How TypeORM Advanced skills are assessed

  • Daily interactive quizzes, graded practical exercises, final project with personalized feedback, pre/post competency self-assessment.

How the TypeORM Advanced course is taught

  • 80% hands-on active pedagogy, pair workshops, real business cases, unlimited post-training video support.

Our method

How Learni guarantees the quality of your TypeORM Advanced training

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
