npm Version

An iconv-lite stream that autodetects the encoding and fallbacks to a specified fallback encoding.

Usage example:

const AutoDetectDecoderStream = require('autodetect-decoder-stream');

let stream = fs.createReadStream('1.csv').pipe(new AutoDetectDecoderStream({ defaultEncoding: '1255' }));

    .on('data', data => {
    .on('end', () => {
      console.log('Done reading.');

Other options that could be passed:

Option Explanation Default
defaultEncoding The fallback encoding, if nothing was detected. If "ASCII" is found, it also assumes that there was not enough data to go on, and falls back. 'utf8'
minConfidence Minimum confidence to require for detecting encodings. See jschardet Depends on jschardet (Currently 0.2)
consumeSize How much data to use for detecting the encoding? - in bytes. 128 bytes
stripBOM Should strip the BOM for UTF streams? true
