Explore how large companies are using node.js

With the rapid development of the Internet, many large companies have begun to use node.js as a back-end development language to improve application performance and response speed. In this article, we’ll take a deep dive into how big companies are using node.js and the benefits they bring when using the language.

What is Node.js?

Node.js is an open source runtime environment based on the Chrome engine. It is lightweight, efficient, cross-platform, and can be used to quickly build scalable network applications. The flexibility and highly customizable build process of Node.js allow programmers to easily extend applications and implement highly customized functionality.

Advantages of Node.js

Node.js is a fast and powerful framework that has the following advantages:

1. Efficient: Node.js uses a Event-driven, non-blocking I/O model maintains efficiency and high throughput when processing client requests. This event-driven model is one of the reasons why it is more efficient than other backend languages.
2. Easy to learn: Node.js uses JavaScript as the programming language, which is a very popular programming language and therefore is easy to learn and understood by developers.
3. Open source: Node.js is an open source framework, which means it is free and developers can freely use, modify and share it.
4. Cross-platform: Node.js is a cross-platform operating environment, which can run on various platforms such as Windows, Linux, and MacOS.
5. Ecosystem: Node.js has a powerful ecosystem, which includes tens of thousands of open source packages and libraries that can extend the functionality and performance of Node.js.

Reasons why big companies use Node.js

Node.js is very useful in developing web applications, which is the main reason why big companies use it. Here are some reasons why big companies use Node.js:

1. Performance: Node.js is ideal for developing high-performance, high-traffic web applications because it can handle large numbers of concurrent connections and is responsive high speed. This is important for large websites and applications that need to handle a large number of requests.
2. Cost Savings: Because Node.js can run on relatively cheap servers, it can significantly reduce the cost of developing and maintaining these applications.
3. Simplicity: The Node.js development process is very simple and straightforward because it is developed using JavaScript, which means developers do not need to learn a new language or framework. In addition, Node.js adopts a callback function-based programming model, which is very friendly and easy to understand for developers.
4. Rapid Development: The rapid response and development speed of Node.js make it a very popular development tool. Companies using this framework can get their applications to market faster and thus achieve revenue faster.

Examples of large companies using Node.js

The following are some typical cases implemented by some well-known companies using Node.js:

1. User management system : Walmart, one of the world's largest retailers, uses Node.js to develop its user management system. This system handles information for millions of users, using Node.js's high concurrency and non-blocking I/O model to achieve high availability and reliability.
2. Real-time applications: LinkedIn, a leading global professional networking platform, uses Node.js to build its real-time communication and application interaction tools. These tools achieve high performance and fast response in high-concurrency scenarios by using Node.js and WebSocket technologies.
3. Advertising platform: eBay, one of the world’s largest online shopping and auction platforms, built its advertising platform using Node.js. Capable of handling millions of ad requests per second, the platform uses the high performance and simplicity of Node.js to achieve efficient ad delivery and conversion.

Conclusion

As Internet technology becomes increasingly mature, Node.js has become one of the preferred development languages ​​chosen by many large companies. Its high performance, efficiency and simplicity are important factors for many companies developing new types of applications. Over time, we can expect more large companies to develop their applications using Node.js as it has proven to be a reliable and fast framework.
