Introduction to fs-monkey

The fs-monkey is a powerful library in the Node.js ecosystem that provides an extensive set of file system manipulation functions. With fs-monkey, you can easily navigate, read, write, and manipulate file system contents in a seamless way. Its primary feature is its versatility and the dozens of useful APIs it offers for development.

Setting Up fs-monkey

Before diving into the examples, make sure you have fs-monkey installed in your Node.js project. You can install it using npm:

  
    npm install fs-monkey
  

API Examples

Reading a File

You can read the content of a file synchronously using the fs.readFileSync method.

  
    const fs = require('fs');
    const content = fs.readFileSync('example.txt', 'utf8');
    console.log(content);
  

Writing to a File

Writing data to a file is straightforward with the fs.writeFileSync method.

  
    const fs = require('fs');
    const data = 'This is a content written by fs-monkey';
    fs.writeFileSync('example.txt', data);
    console.log('File written successfully');
  

Appending Data to a File

To append data to a file, you can use the fs.appendFileSync method.

  
    const fs = require('fs');
    const additionalData = 'More data to append';
    fs.appendFileSync('example.txt', additionalData);
    console.log('Data appended successfully');
  

Checking if a File Exists

Use the fs.existsSync method to check the existence of a file.

  
    const fs = require('fs');
    const fileExists = fs.existsSync('example.txt');
    console.log(fileExists ? 'File exists' : 'File does not exist');
  

Deleting a File

The fs.unlinkSync method allows you to delete a file.

  
    const fs = require('fs');
    fs.unlinkSync('example.txt');
    console.log('File deleted successfully');
  

Listing Directory Content

To list the content of a directory, you can use the fs.readdirSync method.

  
    const fs = require('fs');
    const files = fs.readdirSync('./');
    console.log('Directory content:', files);
  

Example App Using fs-monkey

Let’s build a simple application that creates a new file, writes some data to it, reads it back, and then deletes the file.

  
    const fs = require('fs');

    // Step 1: Create and write to a file
    fs.writeFileSync('appFile.txt', 'Hello, this is a file created by fs-monkey!');
    console.log('File created and written successfully');

    // Step 2: Read the content of the file
    const content = fs.readFileSync('appFile.txt', 'utf8');
    console.log('Read content:', content);

    // Step 3: Delete the file
    fs.unlinkSync('appFile.txt');
    console.log('File deleted successfully');
  

With the fs-monkey library, these typical file operations become simple and efficient, making it a valuable tool in any Node.js developer’s toolkit.
