The word-count module is a lightweight and straightforward Node.js library designed to count words in a given text or string. It provides a convenient way to analyze text content programmatically, which can be useful in various applications such as text processing, analytics, and content management.

Key Features

• Word Counting: Counts the number of words in a text or string.
• Customizable: Allows customization for handling different text formats and configurations.
• Easy Integration: Simple to install and use in Node.js applications.
• Lightweight: Minimal dependencies and efficient for basic word counting tasks.

Detailed Example with Different Texts

Let’s extend the example to work with different types of texts and observe how the word-count module handles them:

const wordCount = require('word-count');

// Example with a simple sentence
const simpleText = "This is a simple sentence.";
console.log(`Word Count for simpleText: ${wordCount(simpleText)}`); // Output: 5

// Example with punctuation
const punctuationText = "Hello, world! How's everything going?";
console.log(`Word Count for punctuationText: ${wordCount(punctuationText)}`); // Output: 5

// Example with line breaks
const multilineText = "This is the first line.\nAnd this is the second line.\nAnd the third.";
console.log(`Word Count for multilineText: ${wordCount(multilineText)}`); // Output: 13

// Example with special characters
const specialCharText = "Special characters: #, $, %, &, * should not count as words.";
console.log(`Word Count for specialCharText: ${wordCount(specialCharText)}`); // Output: 12

// Example with numbers and mixed content
const mixedContentText = "In 2024, there are 365 days. Node.js is 15 years old.";
console.log(`Word Count for mixedContentText: ${wordCount(mixedContentText)}`); // Output: 12

Installation Steps

Step 1:

Make a folder structure for the project.

mkdir myapp

Step 2: 

Navigate to the project directory

cd myapp

Step 3:

• First, we have to install the module using the command given below.
• Open the terminal, navigate to the same folder as your project, and then give the same command to install the module.
• After installation, a package.json file gets added to your project folder, which contains all the information regarding the installed modules.

$ npm install word-count  

Project Structure

The updated dependencies in package.json file will look like:

"dependencies": {
    "word-count": "^0.2.2"
}

Step 4:

• Use the module, To use this module in the application, we have to incorporate the module into the project using the require keyword.
• Give the string to the module to process it and then show the output in the console of the terminal.

const wordCount = require("word-count");

Step 5:

• Run After writing all the code, open the terminal and use the given command to run the JavaScript file.
• This will count the words in the entered string and show the result in the console.
• Give different strings again to again, which will produce different output every time. 

$ node index.js

Example 1: Implementation to show by using word count module.

// index.js

const wordCount = require("word-count");

// String to count
const str = 
"GeeksforGeeks is the best website for computer science";

const count = wordCount(str);

console.log(`Number of words: ${count}`);

Step to Run Application: Run the application using the following command from the root directory of the project

node index.js

Example 2: Implementation to show by using word count module with another example.

// index.js

const wordCount = require('word-count');

const myString = 
'Hello world! This string contains five words.';

const numWords = wordCount(myString);

console.log(numWords); // 5

Step to Run Application: Run the application using the following command from the root directory of the project

node index.js

Note: Enter the different strings of different lengths, to get different results.
