Expo HTTP Server

expo-http-server is an Expo module that provides a simple HTTP server implementation exclusively for iOS and Android React Native applications. It is currently at version 0.1.13 and sees active development with recent updates for Expo 53 compatibility and feature enhancements like custom headers. The module leverages native libraries, Criollo for iOS and AndroidServer for Android, offering local network communication capabilities directly from the mobile device. A key differentiator is its focus on embedding a server within a mobile app, enabling scenarios like local API mocking, inter-app communication, or serving local assets without a remote backend. It notably does not support web environments, which is a crucial limitation to understand.
