node-spawn-async VS node

One thing that surprised me about Node was how slow the default way to shelling out (child_process) could be (probably https://github.com/nodejs/node/issues/14917).

Although according to the linked issue, it has been "fixed", I still ran into a problem during a batch script that was calling imagemagick through a shell for each file in a massive directory; profiling was telling me that starting (not completing) (yes, I was using the async version) the child process increasingly slows, from sub-millisecond for the first few spawns, to eventually hundreds of milliseconds or seconds... Eventually I had to resort to doing only single spawn a bash script that in turn did all the shelling out.

It seems that the linked execa still relies on child_process and therefore has the same issue. It saddens me to see the only package for node that appears to actually fix this and provide a workaround seems to be https://github.com/TritonDataCenter/node-spawn-async and unmaintained.

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.
