Node.js is an open-source, cross-platform JavaScript runtime environment and is used by the likes of Netflix, Spotify and Adobe. Its popularity shows no signs of stopping, with over 6.3 million websites estimated to be using Node.js in 2023 to boost the performance of their real-time applications.
Keeping your Node.js stack up to date is much more than best practice, it’s essential, with the latest versions not only offering better performance and improved features, but the latest security patches too.
Understanding the Node.js lifecycle
Each Node.js version has a life cycle with three main stages: Active, Maintenance, and End of Life. Active versions receive new features and regular updates, maintenance versions only get critical updates, and end-of-life versions no longer receive support or updates, including critical security patches.
While it’s great that Node.js release updates so regularly, it also means it’s important for developers not to rely on outdated versions.

Why is it important to keep Node.js up to date?
Security
Security is a key concern for any outdated application. Older versions of Node.js without current security patches can expose your system to threats, and updating to the latest version is crucial for safeguarding your data and infrastructure as it is designed to protect against newly discovered risks.
Bug fixes
Node.js developers are constantly identifying and fixing bugs in the codebase. Updating to the latest version reduces the chances of unexpected crashes or errors that could impact user experience and ultimately reflect badly on your business, and your productivity.
Better performance
Each Node.js version release includes optimisations for speed and resource management to help minimise CPU usage. If your business handles high traffic or has to process complex tasks, updating to the latest version will allow for faster and more efficient performance, meaning your application can handle more requests or data with fewer resources.
Avoid compatibility issues
Node.js is part of a larger ecosystem, including libraries and frameworks that frequently evolve and are built to support the latest JavaScript language features.
Running an outdated version can lead to compatibility issues, where you’re unable to use the latest versions of libraries, which can make development less efficient and less reliable.
