npm run watch-poll - JavaScript

Introduction

npm run watch-poll is a command used in JavaScript development for watching changes in files and automatically running tasks or scripts in response to those changes. It is typically used in development environments to speed up and automate the development process.

Usage

To use npm run watch-poll, you first need to have Node.js and npm installed on your system. Once you have them set up, follow these steps:

1. Open your project directory in a terminal or command prompt.

2. Run the following command:

   npm run watch-poll
   

Functionality

The npm run watch-poll command enables automatic polling of changes in specified files or directories. Whenever a change is detected, it triggers a specified task or script to be executed automatically.

This command can be configured in the scripts section of your project's package.json file. For example, you might have a script like this:

{
  "scripts": {
    "watch-poll": "webpack --watch"
  }
}

In this case, running npm run watch-poll will start the Webpack bundler in watch mode. Any changes to the files being watched will automatically trigger Webpack to recompile and bundle your JavaScript code.

Benefits

Using npm run watch-poll can greatly improve your development workflow. Some benefits include:

• Automation: You don't need to manually run tasks or scripts every time you make changes. This command automates the process for you.

• Efficiency: It saves time by instantly reflecting changes in your code without the need to manually trigger compilation or other tasks.

• Error detection: Watch mode allows for immediate feedback on any errors or issues in your code by triggering build or test processes whenever changes are made.

• Continuous development: You can continue developing your code without interruption, knowing that it will automatically update and build whenever changes are detected.

Conclusion

npm run watch-poll is a powerful command in JavaScript development that enables automatic monitoring of file changes and execution of tasks or scripts. It is an essential tool for improving development efficiency and maintaining a smooth workflow.
