ExpressJS vs Guzzle: What are the differences?

Developers describe ExpressJS as "Sinatra inspired web development framework for node.js -- insanely fast, flexible, and simple". Express is a minimal and flexible node.js web application framework, providing a robust set of features for building single and multi-page, and hybrid web applications. On the other hand, Guzzle is detailed as "PHP HTTP client that makes it easy to send HTTP requests and trivial to integrate with web services". Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and trivial to integrate with web services.

ExpressJS and Guzzle can be categorized as "Microframeworks (Backend)" tools.

Some of the features offered by ExpressJS are:

• Robust routing
• HTTP helpers (redirection, caching, etc)
• View system supporting 14+ template engines

On the other hand, Guzzle provides the following key features:

• Manages things like persistent connections, represents query strings as collections, simplifies sending streaming POST requests with fields and files, and abstracts away the underlying HTTP transport layer.
• Can send both synchronous and asynchronous requests using the same interface without requiring a dependency on a specific event loop.
• Pluggable HTTP handlers allows Guzzle to integrate with any method you choose for sending HTTP requests over the wire (e.g., cURL, sockets, PHP’s stream wrapper, non-blocking event loops like React, etc.).

ExpressJS and Guzzle are both open source tools. It seems that ExpressJS with 44.6K GitHub stars and 7.48K forks on GitHub has more adoption than Guzzle with 17.1K GitHub stars and 1.95K GitHub forks.

According to the StackShare community, ExpressJS has a broader approval, being mentioned in 854 company stacks & 788 developers stacks; compared to Guzzle, which is listed in 10 company stacks and 7 developer stacks.
