Introduction to isbinaryfile

Working with files often requires distinguishing between binary and text files. isbinaryfile is a robust solution that simplifies this task, making file handling more efficient and reliable. This post introduces isbinaryfile, delving into its various APIs with practical code snippets, and culminates in a comprehensive app example.

Key APIs of isbinaryfile

Below are some key methods provided by isbinaryfile:

1. isBinaryFile.sync

This method synchronously determines if a given file is binary.

    const isBinaryFile = require('isbinaryfile').sync;

    if (isBinaryFile('path/to/file')) {
      console.log('The file is binary');
    } else {
      console.log('The file is not binary');
    }

2. isBinaryFile.async

This method asynchronously determines if a given file is binary.

    const { isBinaryFile } = require('isbinaryfile');

    isBinaryFile('path/to/file', (err, result) => {
      if (err) throw err;
      console.log(result ? 'The file is binary' : 'The file is not binary');
    });

3. isBinaryFile.fromBuffer

This method determines if a given buffer contains binary data.

    const { isBinaryFile } = require('isbinaryfile');

    const buffer = fs.readFileSync('path/to/file');
    isBinaryFile(buffer, (err, result) => {
      if (err) throw err;
      console.log(result ? 'The buffer contains binary data' : 'The buffer does not contain binary data');
    });

4. isBinaryFile.fromBuffer.sync

This method synchronously determines if a buffer contains binary data.

    const isBinaryFile = require('isbinaryfile').fromBufferSync;

    const buffer = fs.readFileSync('path/to/file');
    const result = isBinaryFile(buffer);
    console.log(result ? 'The buffer contains binary data' : 'The buffer does not contain binary data');

App Example using isbinaryfile

Here’s a practical example of how you can leverage isbinaryfile in an application to process files dynamically:

    const fs = require('fs');
    const { isBinaryFile } = require('isbinaryfile');

    const filePath = 'path/to/your/file';

    isBinaryFile(filePath, (err, result) => {
      if (err) {
        console.error('Error: ', err);
        return;
      }
      if (result) {
        console.log('Processing as a binary file');
        // Add your binary file processing logic here
      } else {
        console.log('Processing as a text file');
        const content = fs.readFileSync(filePath, 'utf8');
        console.log(content);
        // Add your text file processing logic here
      }
    });

Using isbinaryfile, we can efficiently determine and process binary and text files dynamically, enhancing application performance and reliability.
