{"library":"express-sse","type":"library","category":null,"description":"express-sse (from `dpskvn/express-sse`) is a lightweight Express.js middleware designed for easily implementing Server-Sent Events (SSE) in Node.js applications. It provides a straightforward API to send real-time, unidirectional updates from the server to connected clients over a standard HTTP connection, making it suitable for dashboards, live feeds, and notification systems. The current stable version is `1.0.0`, released on April 17, 2025, indicating active development and maintenance. Its primary differentiator is its simplicity and focus on one-way communication, which often makes it a more suitable and simpler alternative to WebSockets for server-to-client data streaming scenarios. It handles the necessary HTTP headers and connection management for SSE, allowing developers to focus on sending data without extensive boilerplate.","language":"javascript","status":"active","version":"1.0.0","tags":["javascript","express","sse","server-sent","events","eventsource","middleware","stream","typescript"],"last_verified":"Wed May 27","install":[{"cmd":"npm install express-sse","imports":["import SSE from 'express-sse';","const SSE = require('express-sse');","app.get('/stream', sse.init);"]},{"cmd":"yarn add express-sse","imports":[]},{"cmd":"pnpm add express-sse","imports":[]}],"homepage":null,"github":"https://github.com/dpskvn/express-sse","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/express-sse","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/express-sse/compatibility"}}
