libuv VS node

I wound up on a different team with pre-existing Python code so temporarily shelved my use of Go for a bit, and we used Sanic (an async Python framework built on top of the excellent uvloop & libuv that also powers Node.js) to build some APIs for live channel management & operations. We hand-wrote our OpenAPI and used it to generate documentation and a CLI, which was an improvement over what was there (or not) before. Other teams used the OpenAPI document to generate SDKs to interact with our service.

In the source code of the Node.js opensource project, lib folder contains JavaScript code, mostly wrappers over C++ and function definitions. On the contrary, src folder contains C++ implementations of the functions, which pulls dependencies from the V8 project, the libuv project, the zlib project, the llhttp project, and many more - which are all placed at the deps folder.

Libuv, the C library that gives Node.js its asynchronous, non-blocking I/O capability is responsible for managing the thread pool. Node.js gives you the capability of using additional threads for computationally expensive and long-lasting operations to avoid blocking the event loop.

Node.js is written in C, C++, and JavaScript. The core components of Node.js - the V8 engine and the libuv library - are written in C++ and C, respectively, since these languages provide low-level access to system resources, making them well-suited for building high-performance and efficient applications. JavaScript is mainly used to write the application logic.

Notably upgrades to libuv 1.45 which has io_uring support. Faster file system access! Awhh yeah, it's on.

Remarkable what a mild & unintrusive PR adding io_uring was. https://github.com/libuv/libuv/pull/3952

Well, the single-threaded nature ultimately leads to its biggest downfall. Node.js utilizes a synchronous event loop engineered using Libuv that takes in code from the call stack and executes it.

Let’s see how we could set up a shiny new JavaScript project using the Yarn package manager. We are going to set up nodenv, install Node.js and Yarn, and then initialize a new project that we will then be able to use as a foundation for our further ideas.

Node.js ( https://nodejs.org/ )

Visit the Node.js website and download the latest version of Node.js for your operating system.

Basic knowledge of Node.js and its environment setup. If you don't have Node.js installed on your system, make sure you download and install it from the official Node.js website.

Node.js can be easily installed from its official website. Depending on your operating system, you can choose the Windows, macOS, or Linux version. Node.js packages come with npm (Node Package Manager), which is essential for managing dependencies in your projects.

To get started with Node.js 22.0.0, you can download the latest version from the official Node.js website. For those upgrading from an older version, it is recommended to test your existing applications for compatibility with the new release, particularly if you are using native modules or rely heavily on third-party npm packages.

Node.js (version 10 or higher)

Before we start, ensure that you have Node.js installed on your computer. This is necessary because we will use Node's package manager (npm) to create our Next.js project. If you need to install Node.js, you can download it from the official Node.js website.

Before starting a new project in react, you need to make sure that you have NodeJS install on your system. You can download the latest version of node at https://nodejs.org. Follow the instructions on the node website to do the installation.
