# 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
## Usage
Simply pass a stream and a callback to the `eos`.
Both legacy streams and streams2 are supported.
``` js
var eos = require('end-of-stream');
eos(readableStream, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has ended');
});
eos(writableStream, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has finished');
});
eos(duplexStream, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has ended and finished');
});
eos(duplexStream, {readable: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(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 readable');
});
eos(readableStream, {error:false}, function(err) {
// do not treat emit('error', err) as a end-of-stream
});
```
