The document provides an overview of the MEAN stack, which is a collection of JavaScript technologies used to develop web applications. It consists of MongoDB (a no-SQL database), ExpressJS (a web application framework), AngularJS (a front-end JavaScript framework), and NodeJS (a runtime environment for JavaScript). Each technology is described briefly, outlining its purpose and benefits like performance, scalability, and the use of a single programming language throughout the application stack.
Introduction to mean stack
- 1. What is MEAN ? A Collection of JavaScript based technologies to Develop Web Applications
- 2. Why MEAN stack ! 1. Single language is used throughout the application 2. Support and often enforce the use of the MVC architecture 3. Performance 4. Popularity of JavaScript 5. Open Source Project
- 3. What is NodeJS ? A Run Time Environment for Java Script
- 4. How NodeJS It Compiles the javascript code to Native machine code before execution Event based mechanism
- 5. Why NodeJS Scalable and Fast Web Application Light weight Perfect for real time applications
- 6. Features of NodeJS Asynchronous and Event driven Single threaded No buffering Open Source Npm Node modules
- 7. What is AngularJS MVC based JavaScript Framework
- 8. What AngularJS can do? Develop complex client side application Single Page Applications
- 9. Why this AngularJS Less load on the server Structure the Code and development practice and in MVC/MVVM Reusable components Easily Testable components
- 10. How AngularJS Components Dependency Injection Data binding Directives Filters Services Routes Dirty checking
- 11. What is MongoDB no SQL Database It uses JSON style documents for the data representation
- 12. Why MongoDB JSON everywhere Lightweight Less disk space Scalable architecture No more SQL statements
- 13. How MongoDB Support ad hoc queries Indexing Replication Load Balancing Map reduction and Aggregation tools JavaScript instead of Procedures High performance
- 14. Replication
- 15. What is ExpressJS Server side web and mobile application framework
- 16. Features of ExpressJS Allows and responds to HTTP requests Defines routes Dynamic rendering of HTML pages Helper functions for Web Applications Templating Engines REST support
- 17. What is Vue.Js A progressive framework for building user interfaces
- 18. Features of VueJS Declarative rendering Vue focuses on “view layer” Reactivity Data Binding Directives Components Encapsulation Event Handling Computed properties Transition effects Typescript support
