Node.js is a powerful and widely used JavaScript runtime environment that allows developers to build fast and scalable network applications. As the Node.js community continues to grow, the release of new versions becomes a common occurrence. However, when it comes to choosing which version to use, there are two main to consider: the LTS (Long-Term Support) version and the Current version. In this article, we will explore the differences between these two versions and provide insights to help you make an informed decision.

Before diving into the differences between the LTS and Current versions, it’s important to have a brief understanding of Node.js itself. Node.js is built on Chrome’s V8 JavaScript engine and allows JavaScript to run on the server-side. It provides an event-driven, non-blocking I/O model, making it highly efficient and suitable for applications that require real-time communication and high concurrency.
1. The LTS (Long-Term Support) Version
The LTS version of Node.js is the version that the Node.js Foundation considers to be highly stable, mature, and suitable for most production environments. This version is intended to provide long-term support, with important bug fixes and security updates being regularly released. The LTS version is recommended for applications that prioritize stability, compatibility, and minimized exposure to breaking changes.
Benefits of LTS
- Stability: LTS versions undergo rigorous testing and are known for their stability and reliability.
- Long-term support: The Node.js community provides extended support, ensuring critical fixes and security updates are available for an extended period of time.
- Compatibility: LTS versions prioritize maintaining compatibility with existing packages and modules, reducing the likelihood of compatibility issues.
Considerations for LTS
- New features: LTS versions might not include the latest features and enhancements, as these are usually introduced in the Current version.
- Delayed updates: While stability is a key benefit, the downside is that updates might be delayed. Critical bug fixes and security patches are prioritized, but non-critical updates may take longer to be incorporated.
2. The Current Version
The Current version of Node.js is the latest stable release that includes the most recent features, improvements, and updates. This version is suitable for developers who want to experiment with new functionalities, take advantage of the latest enhancements, and contribute to the Node.js ecosystem. However, it may not be recommended for production environments due to its potentially higher degree of instability.
Advantages of Current
- Latest features: The Current version offers the most up-to-date features, allowing developers to explore and leverage the latest advancements in Node.js.
- Quick updates: Non-critical updates and features are introduced more frequently in the Current version.
- Community involvement: Developers can actively contribute to the evolution of Node.js by experimenting with new features and providing valuable feedback to the Node.js community.
Considerations for Current
- Stability concerns: Since the Current version includes the latest developments, it may be less stable and more prone to bugs or compatibility issues.
- Shorter support period: The Current version receives support for a limited period, after which it transitions into a new LTS version or becomes deprecated.
3. Choosing the Right Version
Now that we have explored the characteristics of both the LTS and Current versions, the choice ultimately depends on the specific requirements and goals of your project. Consider the following factors:
- Stability: If your application prioritizes stability and compatibility, opting for the LTS version may be the best choice.
- Latest features: If you are looking to embrace the latest features and can tolerate occasional instability, the Current version might more suitable.
- Production environment: If you are deploying your application to a production environment, it is generally recommended to use the LTS version for its long-term support and stability.
- Development environment: In a development environment, using the Current version allows for experimentation and taking advantage of the latest features without jeopardizing production stability.
The decision between Node.js LTS and Current versions depends on the specific needs of your project. For production environments where stability and compatibility are crucial, the LTS version provides a reliable choice. On the other hand, the Current version offers the latest features and improvements for developers who want to explore new functionalities. Whichever version you choose, always ensure that you consider the specific requirements and goals of your project.
Common Queries
1. Can I switch from the Current version to the LTS version without any issues?
While it is generally possible to switch between versions, it is recommended to thoroughly test your application after making the transition to identify any compatibility issues. It is advisable to review the release notes and documentation to understand the changes introduced in each version.
2. How often are LTS versions released?
LTS versions of Node.js are typically released every 2 years, with active LTS support lasting for at least 18 months and maintenance LTS support extending for another 12 months.
3. Can I use packages and modules developed for the LTS version in the Current version?
Generally, packages and modules developed for the LTS version should work seamlessly in the Current version. However, it is always recommended to review the package documentation and consider potential compatibility issues.
4. What happens when the Current version reaches the end of its support period?
Once the Current version reaches the end of its support period, it transitions into a new LTS version or may become deprecated. Developers are encouraged to migrate to the latest LTS version to continue receiving support and security updates.
5. Can I use both LTS and Current versions in parallel?
Yes, it is possible to have multiple Node.js versions installed on the same system. This allows developers to work on projects using different versions simultaneously. However, it is important to manage version dependencies and ensure compatibility when using multiple versions.
