File Class v2.1.0

This is a simple Node.js class for reading and writing files. It is written in typescript by me (atom06) for the nexus project

github || npm (you can use the same to download in yarn/pnpm)

Usage

import IO from '@atom06/file';

const file = new IO('test.txt');

// Write data to the file
const [writeSuccess, writeError] = await file.write('Hello, world!');

if (writeSuccess) {
  console.log('Data written to file successfully.');
} else {
  console.error('Error writing to file:', writeError);
}

// Append data to the file
const [appendSuccess, appendError] = await file.append('New data to append.');

if (appendSuccess) {
  console.log('Data appended to file successfully.');
} else {
  console.error('Error appending to file:', appendError);
}

// Read data from the file
const [readSuccess, data] = await file.read();

if (readSuccess) {
  console.log('File data:', data);
} else {
  console.error('Error reading file:', data);
}

API

new File(fileName): File

Create a new File instance with the given file name opening that file.

file.write(data: string): Promise<[boolean, string | unknown]>

file.read(): Promise<[boolean, string | unknown]>

Read the contents of the file. Returns a promise that resolves to a tuple containing a boolean indicating success (true) or failure (false) and either the contents of the file (if successful) or an error object (if failed).

file.append(data: string): Promise<[boolean, string | unknown]>

Append data to the end of the file. Returns a promise that resolves to a tuple containing a boolean indicating success (true) or failure (false) and either undefined (if successful) or an error object (if failed).
