What is codepage?

The codepage npm package is a library for converting data between different character encodings. It supports a wide range of code pages and provides functionality for encoding and decoding text.

What are codepage's main functionalities?

Encoding Conversion

Convert strings between different encodings. In this example, we convert a binary string to UTF-8 and vice versa using code page 437.

var cp = require('codepage');
var utf8String = cp.utils.decode(437, Buffer.from('Hello World', 'binary'));
var binaryString = cp.utils.encode(437, 'Hello World');

Stream Transformation

Create a stream that transforms data from one encoding to another. Here, we create a transform stream that encodes incoming data to code page 437.

var cp = require('codepage');
var stream = require('stream');
var converter = new stream.Transform();
converter._transform = function(chunk, encoding, done) {
  this.push(cp.utils.encode(437, chunk.toString()));
done();
};

Handling Code Pages

Access information about different code pages. This code sample retrieves information about code page 437.

var cp = require('codepage');
var cpInfo = cp[437];
console.log(cpInfo.name);

Other packages similar to codepage

    iconv-lite

    iconv-lite is a popular character encoding conversion library that works similarly to codepage. It supports many encodings and is often used for its simplicity and lightweight nature. Unlike codepage, iconv-lite does not rely on native Node.js modules, making it more portable across different platforms.

    buffer-encoding

    buffer-encoding is another package that offers encoding and decoding of text in Node.js. It provides a simple API for converting between different character encodings. It is similar to codepage but has a smaller footprint and fewer dependencies.

    text-encoding

    text-encoding is a polyfill for the Encoding Living Standard API provided by the WHATWG. It allows for encoding and decoding of text in the browser and Node.js. It is more comprehensive than codepage as it aims to provide a polyfill for the standard API, but it might be heavier in terms of size and complexity.
