Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

node-swatcher

node-swatcher is a lightweight file-watching tool, designed to automatically restart or reload file/script when the specified file changes. This tool is ideal if you want a simple file sandbox where you want to save time by not manually re-executing your file every time you make a change.

Features

  • Watches specified file for changes.
  • Automatically restarts the application on file update.
  • Has a cool json based config feature.

Installation

  • npm i node-swatcher or npm install node-swatcher
  • yarn add node-swatcher
  • Add required script to your package.json Alt Text

Usage

-Using Config File

  1. Create a swatcher.json file in the same directory as file to be run.
  2. Add the configurations as specified :
{
  "serverRestartMessage": "The Server has been restarted",
  "serverErrorMessage": "Try Fixing the error and then , retry",
  "fileChangeMessage": "File has been changed!",
  "filePath": "./demoFile.js",
  "command": "node"
}

Here command refers to the program to be used for running the file specified in the filePath.

  1. Run the command:
  • npm run swatch or yarn swatch

-Using CLI

  • First argument requied is the file path.

  • For running the node-swatcher using CLI we can pass the CLI equivalents of our json config as named args in the command.

For Example :

npm run swatch <filepath> --com=node
  • Remember --com is a required named argument.

Customizations

  • You can customize the restart,error and file change messages as required
