In this article, we will show you how to download Node 12 and why you should. We will also cover some of the benefits and features of Node 12, as well as how to verify and test your installation.
What is Node 12 and What are its Benefits
Node 12 is the current LTS version of Node.js, which means that it is stable, secure, and recommended for most users. Node 12 offers several benefits over previous versions, such as faster startup, better memory management, improved performance, and more features. Let's take a look at some of these benefits in more detail.
Node 12 Features
Diagnostic report: Node 12 provides an experimental diagnostic report feature that generates a JSON file with useful information about the state of the Node.js process, such as CPU usage, memory usage, environment variables, command line arguments, etc. This can help diagnose issues and troubleshoot errors in production environments.
Bundled heap dump capability: Node 12 provides an out-of-the-box heap dump capability that allows you to generate a snapshot of the memory usage of the Node.js process. This can help identify memory leaks and optimize memory consumption.
Worker threads: Node 12 improves the support for worker threads, which are a way of creating multiple threads of execution in Node.js. Worker threads can help improve performance and concurrency by offloading CPU-intensive tasks from the main thread.
Node 12 Performance
Node 12 also delivers significant performance improvements over previous versions, thanks to the updates to the V8 engine, the HTTP parser (llhttp), and the TLS implementation (OpenSSL). Some of these improvements are:
Faster startup: Node 12 reduces the startup time by up to 30% by generating code cache in advance for built-in libraries and embedding it into the binary.
Better memory management: Node 12 improves the default heap limits by automatically configuring them based on the available memory. This can help prevent out-of-memory errors and optimize memory usage for different workloads.
Improved HTTP performance: Node 12 adopts the new llhttp parser, which is faster and more secure than the previous http_parser. This can improve the throughput and latency of HTTP requests and responses.
Enhanced TLS performance: Node 12 updates the OpenSSL library to version 1.1.1, which supports TLS 1.3, the latest version of the Transport Layer Security protocol. TLS 1.3 offers faster and more secure connections, as well as new features such as 0-RTT (zero round-trip time) and post-handshake authentication.
Node 12 Compatibility
Node 12 is compatible with most of the existing Node.js modules and packages, thanks to the efforts of the Node.js community and the Node.js Package Maintenance Working Group. However, some modules may require updating or rebuilding to work with Node 12, especially those that use native addons or deprecated APIs. You can use tools such as npm audit, npm outdated, or node-gyp to check and update your dependencies.
How to Download Node 12 for Different Platforms
