file-write

fileWrite

Its a simple and flexible way to write data to a file in Node.js. It provides a number of options to customize the way data is written to the file, including the ability to overwrite or append to the file, write data synchronously or asynchronously.

Installation

To install file-write, run the following command in your project directory:

npm i file-write

Usage

To use it in EJS module, import the fileWrite function using the import syntax:

import fileWrite from 'file-write';

fileWrite('path/to/file.txt', 'Test data');

To use it in a CJS module, require it in your project:

const fileWrite = require('file-write');

fileWrite('path/to/file.txt', 'Test data');

Options

The filewrite function accepts the following options:

options.encoding

Type: string Default: utf8

The encoding to use when writing the file. All valid Node.js encodings are supported.

fileWrite('path/to/file.txt', 'Test data', {
  encoding: 'utf8'
});

options.overwrite

Type: boolean
Default: true

If set to true, the file will be overwritten with the new data. If set to false, the data will be appended to the file.

// Overwrite the file with new data
await fileWrite('path/to/file.txt', 'Test data', {
overwrite: true
});

// Append data to the file
await fileWrite('path/to/file.txt', 'Appended data', {
overwrite: false
});

options.async

Type: boolean
Default: true

If set to true, the data will be written asynchronously (return a promise). If set to false, the data will be written synchronously.

// Write data to the file synchronously (blocking) return undefined
fileWrite('path/to/file.txt', 'Test data', { async: false });

// Write data to the file asynchronously (non-blocking) and return a promise
fileWrite('path/to/file.txt', 'Test data', { async: true }).then(() => {
  console.log('File written successfully!');
}).catch((err) => {
  console.error(err);
});

options.newLine

Type: boolean
Default: true

It Ensure that contents has a trailing newline before writing it to the file.

options.increment

Type: boolean
Default: false

If set to true and the file already exists, the file will be renamed to include a number in parentheses after the file name. For example, if the file is named foo.txt and increment is true, the file will be renamed to foo (2).txt.

// Increment the file name if the file already exists
await fileWrite('path/to/file.txt', 'Test data', {
increment: true
});

options.exclusive

Type: boolean
Default: false

If set to true, the promise will be rejected with an error if the file already exists. If set to false, the file will be overwritten or appended to depending on the value of the overwrite option.

// Reject the promise with an error if the file already exists
await fileWrite('path/to/file.txt', 'Test data', {
exclusive: true
});
