2. Learn About RESTful APIs
In the MEAN stack, data is transferred between the front-end and back-end using RESTful APIs. Understanding how REST APIs work is crucial for interacting with the server-side logic via HTTP methods like GET, POST, PUT, and DELETE.
3. Build Your First MEAN Stack Application
Start small with a simple project like a to-do list application. Here’s how the components fit together:
- Back-End (Node.js + Express): Set up Express.js to handle HTTP requests from the front-end and interact with MongoDB to fetch or store to-do items.
- Front-End (Angular): Use Angular to build the user interface where users can view and interact with the to-do list.
- Database (MongoDB): Use MongoDB to store the to-do items and handle CRUD (Create, Read, Update, Delete) operations.
4. Practice and Experiment
Once you’ve built your first application, experiment with more complex projects. Add features like authentication, user profiles, or real-time updates using WebSockets.
Career Opportunities with the MEAN Stack
Learning the MEAN stack can open up a variety of career opportunities. Here are some roles you can pursue:
