Advanced tools
The isbinaryfile npm package is used to determine if a file is binary or text. This can be useful in various scenarios such as file processing, content analysis, and data validation.
Check if a file is binary by file path
This feature allows you to check if a file is binary by providing the file path. The function returns a promise that resolves to a boolean indicating whether the file is binary.
const { isBinaryFile } = require('isbinaryfile');
(async () => {
const result = await isBinaryFile('path/to/file');
console.log(result); // true or false
})();
Check if a file is binary by buffer
This feature allows you to check if a file is binary by providing a buffer. The function returns a promise that resolves to a boolean indicating whether the file is binary.
const { isBinaryFile } = require('isbinaryfile');
const fs = require('fs');
(async () => {
const buffer = fs.readFileSync('path/to/file');
const result = await isBinaryFile(buffer);
console.log(result); // true or false
})();
The isbinaryfile package is another option for determining if a file is binary or text. It offers similar functionality to the isbinaryfile package, allowing you to check files by path or buffer.
The file-type package can detect the file type of a buffer or stream. While it is more focused on identifying the file type rather than just determining if it is binary, it can be used to achieve similar results by checking the detected file type.
The binaryextensions package provides a list of binary file extensions. While it does not directly check if a file is binary, it can be used in conjunction with file extension checks to determine if a file is likely to be binary.
Detects if a file is binary in Node.js. Similar to Perl's -B
switch, in that:
null
byte; if it's found, it's binaryMuch of the logic is pretty much ported from ag.
Note: if the file doesn't exist, is a directory, or is empty, the function returns false
.

console.log("It is!")
else
console.log("No.")
fs.readFile(process.argv[2], function(err, data) {
