Introducing Enhanced Alert Actions and Triage Functionality
Socket now supports four distinct alert actions instead of the previous two, and alert triaging allows users to override the actions taken for all individual alerts.

Package description
The end-of-stream npm package is designed to help developers handle the end or error conditions of a stream more easily. It provides a simple way to execute a callback when a stream has finished or failed, making it easier to manage streams in Node.js applications.
Callback on stream end
This feature allows you to execute a callback function when the stream ends or encounters an error. The code sample demonstrates how to use end-of-stream with a file read stream.
const eos = require('end-of-stream');
const fs = require('fs');
const readStream = fs.createReadStream('file.txt');
eos(readStream, function(err) {
if (err) return console.log('Stream had an error or closed early');
console.log('Stream has ended');
});
Promise support
This feature demonstrates how to use end-of-stream with promises, providing a more modern approach to handling stream completion. It uses the `promisify` utility from Node.js to convert the eos callback pattern into a promise.
const eos = require('end-of-stream');
const fs = require('fs');
const { promisify } = require('util');
const eosPromise = promisify(eos);
const readStream = fs.createReadStream('file.txt');
eosPromise(readStream).then(() => console.log('Stream has ended')).catch(err => console.log('Stream had an error or closed early'));
Similar to end-of-stream, stream-ended is a package that provides functionality to detect when a stream has ended. It differs in its implementation and API but serves a similar purpose of stream end detection.
Pump is a package that not only listens for the end of streams but also helps to pipe streams together and handles cleanup in case of a stream ending prematurely. It's more comprehensive than end-of-stream as it also manages the flow between streams.
Readme
A node module that calls a callback when a readable/writable/duplex stream has completed or failed.
npm install end-of-stream
Simply pass a stream and a callback to the eos
.
Both legacy streams and streams2 are supported.
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
});
