chokidar VS fs-extra

for file watching, it might use something similar to https://www.npmjs.com/package/chokidar

First, we need to install chokidar to enable watching and automatically refreshing our files.

The Parcel build command doesn’t support a watch mode like Jest does, but I’d recommend checking out the chokidar package for some help building your own live reload pipeline.

To start, we’re going to use chokidar to watch our file system for changes, so that we can reload when we update a view or a CSS file, not just JavaScript files.

Back when Orthodox File Managers were created, that was the whole list. Nowadays all operating systems have some sort of functionality of letting apps "watch" filesystem for changes, so it would just need to register that it's interested in some files or directories, and then it would receive a callback when that happens. Every operating system does it differently, and there are many gotchas and performance considerations, but a library like chokidar handles most of such issues already.

For watching files to new changes, we can make use of NodeJs inbuilt module, fs. It exposes a function called fs.watchFile but there have been a lot of issues reported by the community saying it’s not reliable. It fires multiple events sometimes for a single file change which results in high CPU utilization. So, to overcome this problem we can use the chokidar package.

When you need more specific watch options, there is a watch_options property as well. For the specifics about that, you might want to check the chokidar docs.

This open-source application has four dependencies: @nuxt/config, @chokidar, minimist and next.

Since updating [email protected] and switching to esm only, many libraries have been replaced to support esm import, but fs-extra has not been The use of esm is correctly supported, and no suitable replacement has been found. After the a PR proposed by us was rejected, I decided to re-release a [fs-extra-unified] that correctly supports the use of esm (https://www.npmjs.com/package/fs-extra-unified) module.

We are dealing with a file that is far too large to be loaded into memory at once. Node cannot buffer the file for us because of the size of it.

Implementing those 3 features was quite simple. For metadata and markdown file, I mainly used an external library: showdown to convert from markdown files to html files as well as parsing metadata from markdown files. However, implementing the support for static assets such as images is a bit more interesting. I had to use another external library called fs-extra to copy assets folder from user to the dist folder. I also had to create another new class called CopyFolder where I used fs.copy method to copy assets folder

The zx project implements a shell script executor similar to Bash but using JavaScript modules. It provides an inbuilt asynchronous JavaScript API to call other commands similar to Bash. Besides that, it provides wrapper functions for several Node.js-based command-line helpers such as chalk, minimist, fs-extra, OS, and Readline.

Node.js has the built-in fs module (fs/promises with async/await) which makes it easy to interact with the file system. On top of that, there are a few convenient libraries such as fs-extra and findit that make common tasks straightforward.
