Why this program matters

  • Without intermediate GraphQL, your REST APIs waste 40% bandwidth on overfetching, inflate cloud costs by 35% annually, frustrate users with x3 latencies vs GraphQL.

  • 70% projects fail due to unoptimized queries, +25% client churn.

  • Risk security breaches without advanced auth, 20% more frequent downtime.

  • Invest 35h, save 10k€/year, become a leader in modern APIs tomorrow.

GraphQL training objectives

  • Design complex GraphQL schemas with unions and interfaces.
  • Develop advanced and optimized resolvers.
  • Implement secure mutations and real-time subscriptions.
  • Optimize performance via DataLoader and caching.
  • Secure APIs against common attacks.
  • Integrate GraphQL into existing stacks.

GraphQL curriculum: 5 modules over 5 days

Module 1 : GraphQL Schema: Advanced Types, Unions, Interfaces (Apollo Server)

Model complex schemas for real-world applications, define enums, inputs, and relationships via hands-on exercises on Apollo Server, build a complete e-commerce schema, test intuitively with GraphiQL, master flexibility for custom queries, and boost productivity from day one.

Module 2 : Queries and Resolvers: Performance and DataLoader

Dive into powerful resolvers, address the N+1 problem with DataLoader, code nested queries on real cases like a blog API, optimize batching and caching, analyze traces with integrated tools, and transform slow APIs into smooth, scalable machines.

Module 3 : Mutations and Subscriptions: Real-Time (WebSockets)

Master atomic mutations with transactions, implement live subscriptions via PubSub, develop a real-time chat on Apollo, handle errors and rollbacks, test full workflows, and deliver dynamic, reactive user experiences that build loyalty.

Module 4 : GraphQL Optimization and Security (Rate Limiting, Auth)

Secure APIs with JWT, depth limiting, and rate limiting via middleware, combat DoS attacks, profile slow queries with Apollo Engine, apply best practices on a banking project, and achieve 50% performance gains.

Module 5 : Integration, Deployment, and Final Project (Docker, CI/CD)

Integrate GraphQL with Express, Prisma, or MongoDB, deploy on Heroku/Docker, set up CI/CD with GitHub Actions, complete a personal capstone project, receive expert feedback, and leave with a production-ready portfolio.

How GraphQL skills are assessed

  • Daily quizzes, code reviews, final Qualiopi-certified project.

How the GraphQL course is taught

  • 70% hands-on with real code, 30% theory, pair exercises, immediate feedback.

Our method

How Learni guarantees the quality of your GraphQL 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.
