HyperExpress: High Performance Node.js Webserver

Powered by `uWebSockets.js`

Motivation

HyperExpress aims to be a simple yet performant HTTP & Websocket Server. Combined with the power of uWebsockets.js, a Node.js binding of uSockets written in C++, HyperExpress allows developers to unlock higher throughput for their web applications with their existing hardware. This can allow many web applications to become much more performant on optimized data serving endpoints without having to scale hardware.

Some of the prominent highlights are:

Simplified HTTP & Websocket API
Server-Sent Events Support
Multipart File Uploading Support
Modular Routers & Middlewares Support
Multiple Host/Domain Support Over SSL
Limited Express.js API Compatibility Through Shared Methods/Properties

See > [Benchmarks] for performance metrics against other webservers in real world deployments.

Documentation

HyperExpress supports the latest three LTS (Long-term Support) Node.js versions only and can be installed using Node Package Manager (npm).

npm i hyper-express

Encountering Problems?

HyperExpress is mostly compatible with Express but not 100% therefore you may encounter some middlewares not working out of the box. In this scenario, you must either write your own polyfill or omit the middleware to continue.
The uWebsockets.js version header is disabled by default. You may opt-out of this behavior by setting an environment variable called KEEP_UWS_HEADER to a truthy value such as 1 or true.
