MEAN Stack is a full-stack web development course using Angular 22 for the frontend and Node.js with Express 5 for a REST API backed by MongoDB 9.0 through Mongoose, covering forms, JWT login and Docker. It suits developers and IT managers with some JavaScript and Angular experience, and you leave able to deploy a CRUD system to production.
MEAN Stack is a set of technologies that uses JavaScript and TypeScript across the whole system: MongoDB for data, Express and Node.js for the API, and Angular for the web front end. Teams can use one language on both frontend and backend, share data models and build business web apps quickly.
This course builds a full-stack system with current versions throughout. It starts with tool setup and a language refresher, then covers Node.js 24 LTS, Express 5 and MongoDB 9.0 through Mongoose 9, before building the front end with Angular 22 using standalone components and signals, connecting it to the API, adding forms and JWT login, and finishing by deploying the whole system to production. (2 days, 6 hours per day, 12 hours in total, Intermediate level.)
Course Details
This course is the 2026 edition of MEAN Stack. It runs for 2 days, 6 hours per day (12 hours in total, 09:00-16:00), as lectures with labs. Intermediate level. This edition moves from Angular 18 to Angular 22 with standalone components, signals and httpResource, uses Node.js 24 LTS, Express 5 and Mongoose 9 with MongoDB 9.0, and uses ES modules instead of CommonJS. It keeps the original core of tool setup, JavaScript fundamentals, Node.js, the event loop, Express, routing, CRUD, third-party APIs and deployment. The previous edition connected to several databases; this edition focuses on MongoDB, as the MEAN name implies, and adds JWT login and deployment with Docker. Learners take home a lab guide and the source code of a full-stack product management system.

Node.js runs JavaScript on a single thread. When it meets work that must wait, such as reading a file, querying a database or calling an API, it hands that work to the system in the background and keeps running other code. When the work finishes, the waiting callback or promise is queued and the event loop runs it once the call stack is empty. This lets a server handle many requests at once, but you should avoid heavy computation that blocks the main thread.
Middleware is a function that runs between receiving a request and sending a response, with access to req, res and next. It is used to parse the body with express.json, log requests, check tokens and permissions, or set CORS before the request reaches its route. Error middleware, which takes four parameters, handles errors in one place, and in Express 5 errors thrown in async functions are forwarded to it automatically, so you do not need try and catch everywhere.
Start by designing resource-based endpoints such as /api/products, then create an Express 5 app with middleware like express.json, split routes with Express Router and move logic into controllers. Connect to MongoDB with Mongoose, validate input with Zod, return the right HTTP status codes and test every endpoint with a REST client or Postman before Angular calls it.
It suits people who want to build full-stack web apps with JavaScript and TypeScript, Angular developers who want to write their own backend, maintainers of older MEAN systems who need to update versions, and IT managers who want to understand the architecture. You should know HTML, CSS and JavaScript, have some Angular experience and understand web services and databases at a basic level. The course opens with a language refresher.
You can build a complete full-stack system: design data in MongoDB, write Express 5 REST APIs with proper validation and error handling, build an Angular 22 front end connected to the API, add forms and JWT login, run everything with Docker and deploy to production. You also take home the sample project's source code to build on for real work.
The course uses Node.js 24 LTS, the Angular CLI, VS Code and Docker Desktop on Windows or macOS. The database is MongoDB 9.0 on a free MongoDB Atlas plan or MongoDB in Docker, with mongosh and MongoDB Compass. APIs are tested with the VS Code REST Client or Postman, and deployment goes through GitHub to Render or a VPS. All software is free, and cloud services use the learner's own accounts.
Node.js lets the JavaScript that developers know from web pages run on the server and on their own machines, from file-handling scripts and command-line tools to web APIs and real-time systems. Current versions include more built-in tools, such as fetch, a…
Microservices split a large system into small services that can be developed, deployed and scaled independently, so teams ship faster and scale only the parts under heavy load. Node.js suits this well because it is lightweight, starts quickly and handles…
The MEVN stack is a set of technologies for full-stack web development in a single language, JavaScript. It brings together MongoDB, a NoSQL database that stores data as documents, Express, a framework for building REST APIs on Node.js, and Vue.js, a popular…
