Node.js was the top technology used by professional developers in 2022

Stack Overflow’s annual Developer Survey confirmed our experience; Node.js continues to grow its use across the globe due to its scalability and performance as well as its ability to integrate seamlessly with a wide range of technologies and databases make it an ideal technology for businesses of all sizes.

The Node.js open-source project, a cross-platform JavaScript run-time environment built on Chrome’s V8 JavaScript engine, allows developers to use JavaScript to create web applications and serve data quickly, securely, and reliably. That’s why professional developers have adopted it broadly; it helps them in many web-development tasks like API development, streaming, and web and mobile applications as it is fully compatible with existing JavaScript libraries (the Top Language according to Github’s Octoverse Report, it can be used to create highly scalable and dynamic web or mobile applications.

NodeJS on an Enterprise Level

Node.js excels at simplifying the development process for enterprises. It requires less code to execute tasks, allowing developers to focus on creating high-quality code rather than endless lines of coding. By utilizing asynchronous I/O and non-blocking event-driven input/output makes it lightweight and efficient for building real-time applications.

Node.js is designed to handle high amounts of requests quickly and efficiently. Its architecture is based on a single-threaded, event-driven model that makes it very efficient at handling concurrent requests. This event-driven design allows Node to handle requests without the need for multiple threads. This makes Node.js applications highly scalable, as multiple requests can be served without additional resources or server hardware.

Additionally, Node.js supports streaming and event-based programming, which allows developers to build asynchronous applications. Asynchronous programming will enable applications to respond quickly to multiple requests without waiting for each request to finish before responding.

Therefore the performance of Node.js applications depends mainly on how well they are coded and optimized. Careful planning and optimizing the application code are essential to achieve high performance. Additionally, Node.js applications benefit from caching, clustering, and other optimization techniques. These techniques can help improve the performance and scalability of Node.js applications.

The number one request we get at NodeSource is to help developers and organizations improve the performance of their Node.js applications. It’s a key reason we built our product N|Solid, to provide the visibility and insights to help identify and resolve issues fast without adding overhead like other APMs (NodeSource Benchmark Tool). And why we offer Professional Services from our Node Experts to go a step further with Performance Audits and Training and Node.js Support.

Optimization techniques in Node.js

In our experience, the most common optimization techniques in Node.js are caching, minification, bundling, optimizing database queries, code splitting, using async functions, and using the Node.js cluster module. Here is a quick overview of each.:

Caching

Caching in Node.js helps improve performance by storing data in memory to be accessed quickly when needed. This helps reduce the time it takes to retrieve data from the server and helps reduce the number of requests needed to be made to the server. Caching also allows data to be stored more efficiently, which is helpful for applications with large amounts of data.

Minification

In Node.js reduces the size of code files and other resources by removing unnecessary characters, such as spaces, new lines, and comments, without altering the code’s functionality. Minifying code can help to enhance the performance of your Node.js applications by reducing download time and improving browser rendering speed.

Bundling

Is the process of combining multiple files or resources into one bundle, which typically has a smaller file size than when all files are separate. Bundling can reduce network latency as fewer requests are needed to retrieve data. It also helps improve application performance as the browser can cache a single large file instead of multiple small ones.

Optimizing database queries

In Node.js involves utilizing techniques such as indexing, query optimization, and caching to ensure that database queries are more efficient and run more quickly. Proper indexing can contribute to faster query times. In contrast, query optimization can reduce the time needed to process a query by ensuring that only the data required is requested from the database.

Code splitting

Is a technique to reduce the amount of code sent to the client when a web page is requested. Code splitting efficiently divides code into smaller bundles and only sends the necessary code to the user when needed. This helps improve web application performance, as the user only needs to download the relevant code for the requested page.

Async functions

In Node.js allow code to be run asynchronously, meaning that the code is not executed sequentially. Instead, asynchronous operations can be executed in parallel and execute operations concurrently. This allows the code to execute faster and in a more efficient way. Additionally, asynchronous functions provide better error-handling capabilities and allow greater control over the flow.

Use of the Node.js Cluster Module

The Node.js cluster module allows you to create a group of child processes (workers) that all share the same server port, making it easy to scale your application across multiple CPU cores. It also provides a powerful way to handle requests in a distributed manner and makes it easier to manage and monitor the performance of your application. The cluster also provides an API for sending messages between workers, allowing them to coordinate their activities.

In addition to these optimization techniques in Node.js, it is important to consider the best development practices in Node.js.

The best development practices in Node.js.for 2023

The list includes, but is not less:

Utilizing the latest version of Node.js and ensuring it is regularly updated. For your production binaries, we recommend using our distribution packages (best maintained, documented, and most used production binaries -NodeSource Node.js Binary Distributions

Implementing modern patterns and techniques such as asynchronous programming and proper error handling.

Leveraging dependency management to reduce code complexity and ensure packages are up-to-date.

Adopting modular development practices to create easily reused and scaled components across projects.

Investing in automated testing to ensure quality and stability in the codebase.

Use security libraries to prevent common vulnerabilities and protect against data breaches.

Optimizing memory and resource usage to keep operating costs low.

And to comply with one or several of these good practices, it is essential to use an APM.

Using an Application Performance Monitoring (APM)

Using an Application Performance Monitoring (APM) tool to monitor your Node.js application lets you gain insights into application performance and identify issues quickly. Some popular APM tools for Node.js include New Relic, AppDynamics, Datadog and N|Solid. Each tool offers performance monitoring, error tracking, and real-time analytics features.

Note: Last year, we released for the community an open-source tool to compare the main APMs in Node.js; we invite you to contribute or use it in your work.

Selecting the right APM for Node.js will depend on the specific needs of your project. However (yes, we are biased 🙂), we believe N|Solid is the best APM for Node.js is the best APM for Node.js; because it provides developers with deeper insights and key integrations and adds security features no other APM can.
