Both legacy streams, streams2 and stream3 are supported. ``` js 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 }); ``` ## License MIT ## Related `end-of-stream` is part of the [mississippi stream utility collection](https://github.com/maxogden/mississippi) which includes more useful stream modules similar to this one. end-of-stream-1.4.4/index.js000066400000000000000000000051661354266206100156430ustar00rootroot00000000000000var once = require('once'); var noop = function() {}; var isRequest = function(stream) { return stream.setHeader && typeof stream.abort === 'function'; }; var isChildProcess = function(stream) { return stream.stdio && Array.isArray(stream.stdio) && stream.stdio.length === 3 }; var eos = function(stream, opts, callback) { if (typeof opts === 'function') return eos(stream, null, opts); if (!opts) opts = {}; callback = once(callback || noop); var ws = stream._writableState; var rs = stream._readableState; var readable = opts.readable || (opts.readable !== false && stream.readable); var writable = opts.writable || (opts.writable !== false && stream.writable); var cancelled = false; var onlegacyfinish = function() { if (!stream.writable) onfinish(); }; var onfinish = function() { writable = false; if (!readable) callback.call(stream); }; var onend = function() { readable = false; if (!writable) callback.call(stream); }; var onexit = function(exitCode) { callback.call(stream, exitCode ?
