The 'encoding' npm package provides utilities for encoding and decoding text in various character encodings. It's often used to convert between different encodings, such as from UTF-8 to ISO-8859-1, or to handle text data that may not be in a standard encoding format.

What are encoding's main functionalities?

Convert encoding of text

This feature allows you to convert a string from one encoding to another. In the code sample, a UTF-8 encoded string is converted to ISO-8859-1.

const encoding = require('encoding');
const utf8String = 'Some UTF-8 text';
const isoString = encoding.convert(utf8String, 'ISO-8859-1');

Decode buffer to string

This feature decodes a buffer into a string using a specified character encoding. In the code sample, a binary encoded buffer is decoded into a UTF-8 string.

const encoding = require('encoding');
const buffer = Buffer.from('encoded text', 'binary');
const decodedString = encoding.convert(buffer, 'utf-8').toString();

Readme

Source

Encoding

encoding is a simple wrapper around iconv-lite to convert strings from one encoding to another.

Initially encoding was a wrapper around node-iconv (main) and iconv-lite (fallback) and was used as the encoding layer for Nodemailer/mailparser. Somehow it also ended up as a dependency for a bunch of other project, none of these actually using node-iconv. The loading mechanics caused issues for front-end projects and Nodemailer/malparser had moved on, so node-iconv was removed.

Install

Install through npm

npm install encoding

Usage

Require the module

var encoding = require("encoding");

Convert with encoding.convert()

var resultBuffer = encoding.convert(text, toCharset, fromCharset);

Where

text is either a Buffer or a String to be converted
toCharset is the characterset to convert the string
fromCharset (optional, defaults to UTF-8) is the source charset

Output of the conversion is always a Buffer object.

Example

var result = encoding.convert("ÕÄÖÜ", "Latin_1");
console.log(result); //<Buffer d5 c4 d6 dc>
