JavaScript technology has made great progress since its release in 1995. We have witnessed the rise of multiple major versions of the ECMAScript specification and the single-page web applications, all powered by the client JavaScript framework. Initially, all JavaScript development and innovation were done in the browser, because that was the only environment that supported the language. Over time, web developers have begun to realize that many of the most useful features of JavaScript (non-blocking, event-driven, languages ??familiar to many) can be used in environments outside of the browser. This initiated the second round of innovation in the JavaScript community, resulting in JavaScript running on servers and databases.
Suddenly, understanding JavaScript doesn't automatically classify you as a "front-end web developer". If you are well versed in the language, you can build servers and databases in addition to the front-end user experience. Now, for the first time developers can build entire web applications using only JavaScript. This trend is often referred to as "full-stack JavaScript" or "pure JavaScript solutions". Building web applications in conjunction with four popular JavaScript technologies: MongoDB, Express, AngularJS, and Node.js has become so popular that it is called the "MEAN stack".
- MongoDB – MongoDB is a so-called NoSQL database. It can be considered as a document database, rather than consisting of rows, columns, and tables. The main use case is storing JSON data; it is perfect for writing applications in JavaScript. It may lack in relational and strict adherence to patterns, but it makes up for the lack of speed, scalability and ease of use.
- Express – Express is a streamlined web server framework designed to make building web servers easier and easier to maintain using Node. It is a form-free framework that provides developers with a high level of customizability, but "low-level" enough to access the underlying Node framework they build. Express provides easy-to-use request routers, cookie management, static file servers, and many other HTTP building blocks needed to create an enterprise-grade web server.
- AngularJS – Angular is a feature-rich client MVC JavaScript framework. It can be used to create powerful and complex single-page web applications. It has built-in two-way data binding and its own HTML-based template language. It also has a feature called "directors" that allows you to extend HTML with new properties or even new elements. Angular is also highly testable, which may not be the most interesting aspect in development, but it is usually the most important and is often overlooked in client code. Finally, it provides conventions and best practices to help developers build client solutions.
- Node – Node is a JavaScript runtime used to build servers and web applications. It provides all JavaScript features found in the browser, as well as additional features for file and network I/O. It uses Google's V8 engine (the same engine used in Google Chrome) to execute JavaScript. It also has a very active developer community and a Node module ecosystem (Express is such a module). While other server-side JavaScript implementations already exist, Node has been the most successful to date in terms of development and adoption by enthusiasts and large companies.
If you are a fan of JavaScript like me, you should be excited about the prospect of building an entire web application using only JavaScript. The MEAN stack is a very hot topic and there is a lot of information online about how to get started with it. In fact, there is so much information that the idea of ??“beginning” seems a bit daunting.
This is why Colin Ihrig and I wrote a book for this. In the book, we discuss each of the four technologies that make up the MEAN stack. We cover the most important features of each technology that will help you get started quickly and increase productivity. However, explanation can only go so far. In addition to many code examples, we will also build a simple HR-style web application step by step throughout the book. You will learn a technique, look at some code examples, and then use the technique step by step to build a real system. At the end of this book, you will have a fully functional web application that you can use and extend by yourself based on the information in this book.
FAQs about full-stack JavaScript development using MEAN
Full stack What is the MEAN stack in JavaScript development?
MEAN stack is a collection of JavaScript-based technologies used to develop web applications. MEAN is the acronym for MongoDB, Express.js, AngularJS, and Node.js. MongoDB is a NoSQL database, Express.js is a web application framework running on Node.js, AngularJS is a JavaScript MVC framework, and Node.js is an execution environment for event-driven server-side and web applications.
Why should I choose the MEAN stack for my web development project?

Node.js is an execution environment for event-driven server-side and web applications. It is built on the V8 JavaScript engine, which means it is very fast. Node.js is also non-blocking, which means it can handle many connections at the same time, making it an excellent choice for real-time applications.
How to get started with MEAN stack development?
There are many resources to help you get started with MEAN stack development. You can learn each technique first and then learn how they work together. There are many tutorials and guides online, as well as books and courses.
What are the prerequisites for learning a MEAN stack?
You should have a basic understanding of JavaScript before you start learning the MEAN stack. It is also helpful to understand the basics of web development, such as HTML and CSS.
Is there an alternative to the MEAN stack?
Yes, there are many alternatives to the MEAN stack. Some popular alternatives include the MERN stack (replace AngularJS with React), the MEVN stack (replace AngularJS with Vue.js), and the LAMP stack (using Linux, Apache, MySQL, and PHP).
What kind of application can I build with the MEAN stack?
MEAN stack is very universal and you can use it to build various applications. This includes single page applications, social network sites, real-time applications, e-commerce sites, and more.

How does garbage collection work in JavaScript?
Jul 04, 2025 am 12:42 AM
JavaScript's garbage collection mechanism automatically manages memory through a tag-clearing algorithm to reduce the risk of memory leakage. The engine traverses and marks the active object from the root object, and unmarked is treated as garbage and cleared. For example, when the object is no longer referenced (such as setting the variable to null), it will be released in the next round of recycling. Common causes of memory leaks include: ① Uncleared timers or event listeners; ② References to external variables in closures; ③ Global variables continue to hold a large amount of data. The V8 engine optimizes recycling efficiency through strategies such as generational recycling, incremental marking, parallel/concurrent recycling, and reduces the main thread blocking time. During development, unnecessary global references should be avoided and object associations should be promptly decorated to improve performance and stability.
How to make an HTTP request in Node.js?
Jul 13, 2025 am 02:18 AM
There are three common ways to initiate HTTP requests in Node.js: use built-in modules, axios, and node-fetch. 1. Use the built-in http/https module without dependencies, which is suitable for basic scenarios, but requires manual processing of data stitching and error monitoring, such as using https.get() to obtain data or send POST requests through .write(); 2.axios is a third-party library based on Promise. It has concise syntax and powerful functions, supports async/await, automatic JSON conversion, interceptor, etc. It is recommended to simplify asynchronous request operations; 3.node-fetch provides a style similar to browser fetch, based on Promise and simple syntax
JavaScript Data Types: Primitive vs Reference
Jul 13, 2025 am 02:43 AM
JavaScript data types are divided into primitive types and reference types. Primitive types include string, number, boolean, null, undefined, and symbol. The values are immutable and copies are copied when assigning values, so they do not affect each other; reference types such as objects, arrays and functions store memory addresses, and variables pointing to the same object will affect each other. Typeof and instanceof can be used to determine types, but pay attention to the historical issues of typeofnull. Understanding these two types of differences can help write more stable and reliable code.

Oracle's trademark dispute with Deno Oracle's attempt to register a "JavaScript" trademark has caused controversy. Ryan Dahl, the creator of Node.js and Deno, has filed a petition to cancel the trademark, and he believes that JavaScript is an open standard and should not be used by Oracle
React vs Angular vs Vue: which js framework is best?
Jul 05, 2025 am 02:24 AM
Which JavaScript framework is the best choice? The answer is to choose the most suitable one according to your needs. 1.React is flexible and free, suitable for medium and large projects that require high customization and team architecture capabilities; 2. Angular provides complete solutions, suitable for enterprise-level applications and long-term maintenance; 3. Vue is easy to use, suitable for small and medium-sized projects or rapid development. In addition, whether there is an existing technology stack, team size, project life cycle and whether SSR is needed are also important factors in choosing a framework. In short, there is no absolutely the best framework, the best choice is the one that suits your needs.
Understanding Immediately Invoked Function Expressions (IIFE) in JavaScript
Jul 04, 2025 am 02:42 AM
IIFE (ImmediatelyInvokedFunctionExpression) is a function expression executed immediately after definition, used to isolate variables and avoid contaminating global scope. It is called by wrapping the function in parentheses to make it an expression and a pair of brackets immediately followed by it, such as (function(){/code/})();. Its core uses include: 1. Avoid variable conflicts and prevent duplication of naming between multiple scripts; 2. Create a private scope to make the internal variables invisible; 3. Modular code to facilitate initialization without exposing too many variables. Common writing methods include versions passed with parameters and versions of ES6 arrow function, but note that expressions and ties must be used.
Handling Promises: Chaining, Error Handling, and Promise Combinators in JavaScript
Jul 08, 2025 am 02:40 AM
Promise is the core mechanism for handling asynchronous operations in JavaScript. Understanding chain calls, error handling and combiners is the key to mastering their applications. 1. The chain call returns a new Promise through .then() to realize asynchronous process concatenation. Each .then() receives the previous result and can return a value or a Promise; 2. Error handling should use .catch() to catch exceptions to avoid silent failures, and can return the default value in catch to continue the process; 3. Combinators such as Promise.all() (successfully successful only after all success), Promise.race() (the first completion is returned) and Promise.allSettled() (waiting for all completions)
What is the cache API and how is it used with Service Workers?
Jul 08, 2025 am 02:43 AM
CacheAPI is a tool provided by the browser to cache network requests, which is often used in conjunction with ServiceWorker to improve website performance and offline experience. 1. It allows developers to manually store resources such as scripts, style sheets, pictures, etc.; 2. It can match cache responses according to requests; 3. It supports deleting specific caches or clearing the entire cache; 4. It can implement cache priority or network priority strategies through ServiceWorker listening to fetch events; 5. It is often used for offline support, speed up repeated access speed, preloading key resources and background update content; 6. When using it, you need to pay attention to cache version control, storage restrictions and the difference from HTTP caching mechanism.
