    > It’s typical to listen to this stream of events and use chained if-else statements to determine an action based on the type of the events that occur.

    You'd think something like directory watching would have a clear set of events that would make nice objects with consistent meanings, but in my experience file watching gets crazy complicated, and can have all sorts of edge cases.

    Just take a looked here for all the various edge cases that crop up:

    Then you have linux, windows, macos, and maybe you want to abstract over some underlying implementation like chokidar vs fb/watchman vs webpack/watchpack. Every new OS release could also cause things to change.

    So usually its going to be a bunch of if-else statements hacked together to get around edge cases, and have to be revisited later on.

    Any attempt to abstract this into objects, just obfuscates things. And OO forces you to name things, when in fact they might be un-nameable. `FileSystemModifyEventExceptWhenXAndYAndSometimesZ`.

    The behavior might rely on a series of events together, so the object hierarchy must be re-worked.

    OO has this rosy idea that we just have to come up with the perfect hierarchy, but things change in unexpected ways, and everything must have a descriptive noun.

    Next, you can use a library like chokidar to listen for changes in your source directory. Create a ws server, and whenever a file changes, send a message.
  • How does nodemon works under the hood?

    As another has mentioned, nodemon uses chokidar under the hood for the actual file watching part.
  • Turbowatch – Extremely fast alternative to Nodemon

    At the end of the day, ironically, Nodemon does not even implement file watching functionality. It is a thin wrapper around chokidar (see source code), and the way it is being used is neither efficient (CPU and your battery usage) or performant. So it is not a false argument, just perhaps not the most appealing.

    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.
  • Have you ever thought, how ‘nodemon’ works internally? Let’s build our own ‘nodemon’ in under 10 minutes!
    4 projects | | 2 Jun 2021
    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.
