Full Stack MERN Training – React, Node.js, MongoDB & Express

• The starting point: understanding the architecture of a modern web application before writing a single line. We situate the role of the full stack developer, clarify the client-server dialogue and the logic of the MERN stack (MongoDB, Express, React, Node.js), then compare the two major API styles — REST and GraphQL — to know when to favour each. The day then sets up a complete, tooled working environment (Node.js, npm, Visual Studio Code, Vite) and introduces the tools that speed up the modern development cycle (SWC, esbuild, nodemon).
• Hands-on workshop: initialise a full stack project from scratch, configure Vite and automatic server reloading, and confirm that the front-end and back-end communicate.

• The heart of the application’s visible layer. We lay the foundations of React (JSX, virtual DOM, one-way data flow), then leverage what recent versions bring (React 19 and beyond: Suspense, concurrent rendering, server components). We structure a project with Vite, style the interface (CSS Modules, Tailwind CSS) and, above all, master hooks, the true backbone of modern React: useState, useEffect, useReducer, useMemo, useCallback and component memoisation.
• Hands-on workshop: build an interface made of several reusable components, manage their local state, then track down and eliminate unnecessary re-renders using memoisation hooks.

• As soon as an application grows, the flow of information becomes the central challenge. We distinguish server state from client state and adopt the right tools for each: TanStack Query for asynchronous data (caching, revalidation, loading states), Redux Toolkit and its middleware for structured global state, Zustand as a lightweight alternative. Finally, we connect the interface to the server by consuming REST and GraphQL APIs (fetch, Axios, Apollo Client).
• Hands-on workshop: wire the interface to the project’s API, cache and refresh data with TanStack Query, then compare the approach with a Redux Toolkit store.

• Crossing to the other side: the server. We explain the event-driven, non-blocking model that makes Node.js distinctive, then build a REST API with Express.js. We set up the middleware chain (authentication, validation, logging), harden the API (Helmet, rate limiting) and open up to GraphQL by creating an API with Apollo Server.
• Hands-on workshop: build a complete REST API with Express, add validation and logging middleware, then expose the same resource via a GraphQL query.

• Every application needs memory. We contrast MongoDB’s document approach with relational databases (PostgreSQL, MySQL) and learn to choose according to need. We model data in both paradigms, integrate Mongoose on the NoSQL side and Prisma on the SQL side, then tackle what separates a slow database from a fast one: query optimisation and indexing strategies.
• Hands-on workshop: model the project’s schema, perform read and write operations with Mongoose then with Prisma, and measure the effect of an index on a query.

• A connected application must know who does what, and defend itself. We set up JWT token-based authentication, delegate identity via OAuth 2.0 (Google, GitHub sign-in), protect passwords (bcrypt) and systematically validate incoming data. We then review the most common web vulnerabilities — XSS, SQL injection — and how to prevent them, not forgetting CORS configuration.
• Hands-on workshop: secure the project’s API with a JWT authentication flow, add an OAuth login, then fix two deliberately introduced flaws (XSS and injection).

• Shipping fast means being able to change without fear. We build a multi-level testing strategy: unit and integration tests with Vitest, component tests with React Testing Library, end-to-end tests with Cypress. We measure coverage, stress-test the tests’ robustness through mutation (Stryker) and mock network calls with MSW.
• Hands-on workshop: write a test suite covering a React component and an API endpoint, then automate a full user journey with Cypress.

• An application only truly exists once it is in production. We first optimise the build for going live (Vite, esbuild), review hosting platforms (Netlify, Vercel, Heroku, Render, AWS), then automate the whole cycle with a GitHub Actions pipeline. Finally, we set up application monitoring (Sentry, Datadog) to detect and diagnose incidents.
• Hands-on workshop: build an optimised version of the project, deploy it via a GitHub Actions pipeline, then wire up error reporting in production.

• Some applications must react instantly and handle load. We implement real-time communication (WebSockets, Socket.IO), introduce caching and queues with Redis, cover load balancing and clustering, then the handling of asynchronous and deferred tasks (Bull, Agenda).
• Hands-on workshop: add a real-time feature to the project (notifications or instant messaging), then offload a heavy task to a Redis queue.

• The wrap-up module: making it all last over time. We structure a full stack project with a clear separation of responsibilities, apply proven patterns (Repository, dependency injection), open up to domain-driven design (DDD), externalise configuration (dotenv) and document the API for the team and integrators (Swagger, Postman).
• Hands-on workshop: reorganise the capstone project into a layered architecture, document its API with Swagger and write a reference Postman collection.

• A complete, up-to-date MERN stack (React 19, Node.js, Express, GraphQL, Prisma), covered end to end.
• Around 70% hands-on work on a capstone project: from the UI component to production deployment.
• A broad scope — front-end, back-end, data, security, testing, deployment — to become truly self-sufficient.
• Designed for a developer wanting to cover the entire modern JavaScript chain.
• Small group of 1 to 3 participants, session guaranteed from a single enrolment.
• One month of post-course support from MFE-IT trainers.

For a developer who already knows the basics of the web (HTML, CSS, JavaScript) and wants to cover the entire full stack JavaScript chain, from React to Node.js. It is not intended for programming beginners.

No. React, Node.js and ORMs are covered from the fundamentals. Solid practical experience with JavaScript (ideally ES6 and later) and object-oriented programming basics are enough to get started.

Very hands-on: around 70% of the time is spent in workshops, on a MERN capstone project built and deployed progressively over the six days.

Both. The curriculum covers the document approach with MongoDB and Mongoose as well as the relational approach with PostgreSQL and Prisma, so you can choose according to need.

No. It is funded directly by the company. A tailored quote is drawn up based on the number of participants and the chosen format.
