It lets you use HTML as your template language and allows you to extend HTML syntax to express your application’s components clearly and succinctly. Then ExpressJS sends a response back to the NodeJS and then NodeJS forwards it to the AngularJS to display the result.ĪngularJS is a structural framework for dynamic web apps.MongoDB retrieves the data & returns the response back to the ExpressJS.In phase 3, which is ExpressJS makes the request to the database.NodeJS is a server-side language in JavaScript. After that, the request enters phase 2 which is NodeJS.AngularJS is a client-side language in JavaScript. When the client makes any request it is firstly processed by the AngularJS.The working of the MEAN Stack is explained below in the figure properly. In other technologies, there are different languages used for front and back-end but MEAN is written in one language for both server-side and client-side execution. It is effortless & easy to use for both the back-end and front-end. MEAN is a free and open-source JavaScript software stack for building dynamic websites and web apps. AngularJS helps to develop SPAs (single-page applications) which normally include all the information or functionalities for the user on a single page. Though MEAN stack is not ideal for every application, there are other uses where it easily offsets. have also shifted to Node.js Use Cases of MEANīecause of its enhanced scalable and handling capacity of concurrent users, it is much more favored for developing cloud-native applications. Not just the start-ups and SMBs but also big companies like Walmart, PayPal, Yahoo, Netflix, Uber, LinkedIn, etc. In addition to this, it is easy to use, flexible to understand, and moreover assists the developers to customize as per the requirements.Ī massive module library of node.js and the use of JSON to transfer the data are a few other features of MEAN. The MEAN components are open source in other words, the stack gets updated regularly. It supports the MVC (Model View Controller) architecture. This is a blessing for the JavaScript developers who have invested their time and money in learning JavaScript for client-side tasks. One of the most important benefits of all is that it lets the developer write the entire code in JavaScript from client to server. The amalgamation of all makes a clean, coherent mechanism for moving data from the user to the disk farm and back again. On the client-side, AngularJS provides a clean way of adding interactive functions and AJAX-driven rich components. Node.js provides a better nexus for running your server, while Express.js helps to standardize how you build your websites. MongoDB offers a more flexible, accommodating layer for storing data. it works on the back-end, away from the user’s eyes to fetch relevant data or perform operations on the same. This is a runtime environment, which runs server-side web applications, i.e. It builds upon the classic HTML framework style and extends it to web apps M = MongoDB, a popular database manager which implements a NoSQL structure.Į = Express.js, a framework that supports and is used to host Node.js projects.Ī = Angular.js, yet another framework for building apps. From client to server to database, MEAN is full-stack JavaScript. MEAN is an acronym for MongoDB, ExpressJS, AngularJS, and Node.js. MEAN is a free and open-source JavaScript software stack for building dynamic websites and web applications or we can say that MEAN stack is a collection of JavaScript-based technologies used to develop web applications.
