Learn MERN stack with online courses and programs
What is MERN stack?
MongoDB provides developers with a database they can connect to, while Express builds the back-end framework. The React library allows them to add interactive elements to their applications, and Node.js enables applications to run outside a user’s browser.

MERN stack tutorial curriculum
Learners who choose to pursue a bachelor’s degree in computer science or a related topic may encounter the MERN stack in their coursework. For individuals interested in learning the MERN stack in a shorter time frame, a coding boot camp may also cover MongoDB, Express, React, and Node.js.
A comprehensive MERN stack tutorial will equip you with the necessary skills and knowledge to develop modern, feature-rich web applications. The curriculum for a MERN stack tutorial will typically be divided into four key areas:
1. MongoDB: a document database used for data modeling and schema design, writing queries using the Mongo Shell, creating CRUD operations, connecting to applications using a driver library, using the Mongoose ODM framework, indexing strategies, and sharding data clusters.
2. Express.js: a web framework used for server-side rendering and middleware composition. Learners can gain experience building server-side APIs using the Express framework and securing API endpoints using authentication and authorization protocols.
3. React: a client-side web framework used for developing user interfaces, such as state management, virtual DOM manipulation, and components design pattern. It is also involved in debugging production deployments with React Developer tools, routing in React Applications, and integrating UI libraries into React applications.
4. Node.js: a server environment used for organizing project structure, package dependencies management, and CI/CD pipeline automation, and other development needs.

MERN is a versatile technology stack used in various positions to create web applications from front to back. Some standard job titles for positions that use the MERN stack include:
MERN stack developer: a full-stack developer specializing in building web applications using MongoDB, Express, React, and Node.js. Developers in this role are responsible for using this stack to design and implement the user interface, write server-side code to define the application's logic, and integrate the application’s front and back ends. They may also be responsible for testing, debugging, and deploying the application.Footnote 3
Full-stack developer: a developer who has the knowledge and skills to work on all layers of a web application or software project. This includes the front end (client side), back end (server side), and database. Full-stack developers may work on tasks such as designing and implementing the user interface, writing server-side code to define the application's logic, and integrating the front and back ends of the application.Footnote 5
You can acquire these skills in various ways, including boot camps or as part of a bachelor's degree program or master's degree program. The individual job requirements will depend on the role and employer, so make sure to research the professional position you hope to apply for before setting down a specific learning path.
