chardet Build Status

Chardet is a character detection module written in pure Javascript (Typescript). Module uses occurrence analysis to determine the most probable encoding.

  • Packed size is only 22 KB
  • Works in all environments: Node / Browser / Native
  • Works on all platforms: Linux / Mac / Windows
  • No dependencies
  • No native code / bindings
  • 100% written in Typescript
  • Extensive code coverage

Installation

npm i chardet

Usage

To return the encoding with the highest confidence:

const chardet = require('chardet');

chardet.detect(Buffer.from('hello there!'));
// or
chardet.detectFile('/path/to/file').then(encoding => console.log(encoding));
// or
chardet.detectFileSync('/path/to/file');

To return the full list of possible encodings use analyse method.

const chardet = require('chardet');
chardet.analyse(Buffer.from('hello there!'));

Returned value is an array of objects sorted by confidence value in decending order

[
  { confidence: 90, name: 'UTF-8' },
  { confidence: 20, name: 'windows-1252', lang: 'fr' }
];

Working with large data sets

Sometimes, when data set is huge and you want to optimize performace (in tradeoff of less accuracy), you can sample only first N bytes of the buffer:

chardet
  .detectFile('/path/to/file', { sampleSize: 32 })
  .then(encoding => console.log(encoding));

  • UTF-8
  • UTF-16 LE
