@localtools/base64

A Node.js library for encoding and decoding text as Base64.

Installation

To install @localtools/base64, run the following command:

npm install @localtools/base64

Usage

To use @localtools/base64, import the Base64 class and call its encode and decode methods:

import { Base64 } from '@localtools/base64';

const encodedText = Base64.encode({ text: 'hello world' });
console.log(encodedText); // Outputs: "aGVsbG8gd29ybGQ="

const decodedText = Base64.decode({ base64Text: encodedText });
console.log(decodedText); // Outputs: "hello world"

The encode method takes an object with a text field, and returns the Base64 encoding of the text. The decode method takes an object with a base64Text field, and returns the text represented by the Base64 encoding.

API

  • start (number): The index of the first character in the text to encode. Defaults to 0.
  • end (number): The index of the last character in the text to encode. Defaults to text.length.

Returns

A Base64-encoded string.

Base64.decode(args: DecodeArgs): string

Decodes a Base64 string as a text string.

Parameters
