node-swatcher v1.1.12

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

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.

3. 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.
