Node.js has a huge and active community that has contributed to the rich ecosystem, consisting of frameworks, libraries, and tools presented through the npm package manager. As a developer, you can effortlessly extend and add new functionalities to your app. Some tools like Express.js simplify the development cycle of web apps, leading to reduced development time.
Limitations of Node.js
After exploring the strength of Node.js in building backend functionality, we need to know that it never lacks its imperfections. Some of the limitations to consider include:
Node.js is good at handling multiple requests smoothly. The challenge it faces is its single-threaded architecture, making it difficult to process CPU-bound tasks. It becomes a performance bottleneck, especially when carrying out applications or tasks requiring heavy computational power.
Limited Support for Databases
The initial design of Node.js targeted the support for web apps, resulting in limited database support except for MongoDB. Such a limitation is a bottleneck when you aim to integrate Node.js with existing databases and also means that developers may not implement Node.js in other application types.
Node.js is highly asynchronous and relies on callbacks, hindering writing clean and easy-to-maintain code. It becomes hectic, especially for complex apps that rely on several asynchronous functions. Such an issue is what we refer to as callback hell, where there are cases of nested code that become a challenge to follow.
Node.js apps are prone to memory leaks, making developers face stability issues and performance problems. There is the reliance of Node.js on a garbage collector for managing memory, which may sometimes fail to reclaim the memory as fast as needed.
Use Cases of Node.js
- Backend Development: Node.js creates lightweight server-side apps, backend services, and scalable RESTful APIs. The APIs are designed to handle multiple connections at ago.
- Real-time Applications: The asynchronous nature of Node.js helps create apps that need real-time data exchange. Such apps include online gaming, live updates, collaboration tools, and chat apps.
