Steps
5

  1. Node.js fundamentals

    3 to 4 weeks

    Learn how JavaScript runs on a server: modules, npm, the file system, environment variables, and asynchronous code. Build a few command-line tools.

  2. APIs with Express

    4 to 5 weeks

    Build a REST API with Express: routes, middleware, validation, error handling, and status codes. Test every endpoint with Postman.

  3. MongoDB

    3 to 4 weeks

    Learn documents, collections, queries, indexes, and data modelling. Connect your Express API to a free MongoDB Atlas database.

  4. Authentication and security

    3 weeks

    Add sign-up and login with hashed passwords and tokens. Learn the most common web security mistakes and how to avoid them: injection, broken access control, and leaked secrets.

    • OWASP Top 10 Documentation, English, free Read the summary of each risk and check your own project against it.

  5. Full-stack project and deployment

    5 to 6 weeks

    Build one complete app: React frontend, Express API, MongoDB database, login, and deployment. Handle CORS and environment variables properly, and write a README explaining how it works.
