    Build status

    Usage

    Simply pass a stream and a callback to the eos. Both legacy streams, streams2 and stream3 are supported.

    var eos = require('end-of-stream');
     
    eos(readableStream, function(err) {
      // this will be set to the stream instance
        if (err) return console.log('stream had an error or closed early');
        console.log('stream has ended', this === readableStream);
    });
     
    eos(writableStream, function(err) {
        if (err) return console.log('stream had an error or closed early');
        console.log('stream has finished', this === writableStream);
    });
     
    eos(duplexStream, function(err) {
        if (err) return console.log('stream had an error or closed early');
        console.log('stream has ended and finished', this === duplexStream);
    });
     
    eos(duplexStream, {readable:false}, function(err) {
        if (err) return console.log('stream had an error or closed early');
        console.log('stream has finished but might still be readable');
    });
     
    eos(duplexStream, {writable:false}, function(err) {
        if (err) return console.log('stream had an error or closed early');
        console.log('stream has ended but might still be writable');
    });
     
    eos(readableStream, {error:false}, function(err) {
        // do not treat emit('error', err) as a end-of-stream
    });
