The Node.js framework is really popular among developers. Still, every developer should be aware of a few little-known facts.
Let’s Explore the Hidden Facts of Node.js
1. Cluster Module
- Use of multiple CPU cores: Even though Node.js is a single-threaded framework, multiple CPU cores are possible by generating child processes. It is possible to use a cluster module.
- Load Balancing: It leads to the best performance when load distribution is possible among worker processes.
- The architecture it employs is called “master-worker“; master processes assign tasks to worker processes and manage incoming connections.
2. Async Hooks
- Tracking Asynchronous Resources: To track asynchronous resource lifetimes, low-level API is provided by Async hooks.
- Custom Metrics: To check the behavior of applications, one can create custom metrics and insights.
3. Deno
- While Node.js supports TypeScript, Deno is designed from scratch with TypeScript in mind.
- Modular Ecosystem: Based on ES modules for a more modern module system.
- Secure by Default: Deno includes more measures for security, therefore avoiding many of the common vulnerabilities.
4. Node.js REPL: More Than Just a Shell
- Debugging: REPL provides interactive debugging, inspecting objects, and testing code snippets.
- Custom Commands: Adding more functionality with custom REPL commands.
- Experimentation: A great tool for quick experiments and learning.
5. True Parallelism
- CPU-bound Tasks: For computationally intensive tasks, worker threads perform actual parallelism using multiple contexts for running JavaScript.
- Careful Memory Management: If powerful, worker threads are very careful about memory management due to probable shared memory hazards.
- Isolate Resource Usage: This does not block the main event loop.
Additional Tips and Tricks
- Memory Management: How V8’s garbage collector works in order not to allow memory leaks.
- Error Handling: Good error handling and logging.
- Code Organization: Following best practices like modularity and clean code.
- Community and Resources: Large Node.js community and resources to learn from/ask for support.
You will be able to unlock the full power of this framework while creating high-performance and scalable applications by discovering some of the hidden best practices for Node.js.
