Tons of Solutions Engineering work done today for the rest of the CS team! Headway, Howard Hanna, Engels, Brighton, etc. Also completed Datasnippers auth flow and worked on Anthology's script. Cloned Anthology's courses (900..) and will clone Full Story on Monday.

# end-of-stream
|
||||
|
||||
A node module that calls a callback when a readable/writable/duplex stream has completed or failed.
|
||||
|
||||
npm install end-of-stream
|
||||
|
||||
[](https://travis-ci.org/mafintosh/end-of-stream)
|
||||
|
||||
## Usage
|
||||
|
||||
Simply pass a stream and a callback to the `eos`.
|
||||
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
|
||||
});
|
||||
```
