# 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, 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
|
||
|
|
});
|
||
|
|
```
