This makes it easier to manage communication between the client side and the database, streamlining the development process for full stack developers using an Express server.
One of the key benefits of Express.js is its ability to organize functionality with middleware and routing while adding utilities to Node.js’s HTTP objects. This helps avoid clutter, while also providing strong error handling and templating functions.
The simplicity of Express.js allows developers to quickly build production-ready services, making it an invaluable tool in the MEAN stack. With Express.js, developers can create dynamic and scalable web applications with ease.
AngularJS
AngularJS, developed by Google, is a client-side framework specifically tailored for creating dynamic single-page applications (SPAs). It operates at the front end, enabling the development of interactive user interfaces in web applications. The use of AngularJS facilitates a smooth flow of information between all parts of the application, for a cohesive user experience. Additionally, AngularJS is widely recognized for its efficiency in building robust applications.
The Angular CLI (Command Line Interface) simplifies the creation of AngularJS projects, making it easier for developers to set up and manage their applications. One of the strengths of AngularJS is its ability to maintain backward compatibility while informing developers about breaking changes early. This ensures that applications remain up to date and compatible with new versions of the framework.
Node.js
Node.js is a JavaScript runtime environment that executes JavaScript code on the server side, enabling developers to build scalable applications. Its asynchronous nature allows it to handle many connections simultaneously without blocking, which improves application performance. This makes Node.js an ideal choice for applications that require high scalability and performance in the JavaScript programming language.
One of the significant strengths of Node.js is its scalability, supporting up to a million simultaneous connections. This capability is crucial for applications that need to manage a large number of concurrent users. With Node.js, full stack developers can create server-side environments that efficiently handle resource-intensive requests. This ensures that web applications built with the MEAN stack are both scalable and performant.
