Introduction Security is a critical aspect of application development, and Node.js is no exception. In this blog, we’ll cover best practices for securing your Node.js applications, including handling sensitive data, managing dependencies, and preventing common vulnerabilities. 1. Keep Dependencies Updated Tip: Regularly update your dependencies to patch known vulnerabilities. Example:
Introduction Node.js is known for its single-threaded, event-driven architecture, which excels at handling I/O-bound operations. However, for CPU-bound tasks, this can lead to performance bottlenecks. Node.js 12 introduced the worker_threads module to address this limitation by allowing JavaScript to run in parallel threads. In this blog, we will explore how to use worker_threads to improve […]
Introduction Streams are a powerful feature of Node.js that allow you to process data in chunks rather than loading it all into memory at once. This approach is particularly useful when dealing with large files or data sources. In this blog, we will explore how to use streams effectively in Node.js to handle large datasets […]
Introduction Node.js has always been popular for its non-blocking, event-driven architecture. With the introduction of async/await in Node.js 7.6 and its subsequent enhancements in later versions, asynchronous programming has become more intuitive. This blog will explore how to leverage async/await to make your Node.js code more readable and maintainable. Understanding Callbacks and Promises Before async/await, […]
Tip: Use HTTP/2 to improve performance with features like multiplexing and header compression. Example: Reason: HTTP/2 provides performance improvements over HTTP/1.1, particularly for applications with many concurrent connections.
Tip: Use environment variables to manage configuration settings for different environments (development, testing, production). Example: Reason: Environment variables provide a flexible way to manage configuration and sensitive data without hardcoding them into your application.
Tip: Properly handle uncaught exceptions and unhandled promise rejections to prevent application crashes. Example: Reason: Helps in managing errors gracefully and avoiding abrupt crashes, though it is often better to fix the root causes of these issues.
Tip: Implement graceful shutdown procedures to ensure ongoing requests are completed before exiting. Example: Reason: Ensures that active connections are properly closed and resources are released before the application exits.
Tip: Use process.hrtime() for accurate timing measurements in your application. Example: Reason: Provides high-resolution time measurements, useful for performance profiling and benchmarking.
Tip: Use the –trace-warnings flag to get detailed stack traces for warnings, which can help diagnose issues more effectively. Example: Reason: Provides more context for warnings that could indicate potential issues in your code.
