Little API

`little-api` is a JavaScript library designed for creating simple JSON-over-HTTP/WS RPC servers and clients with minimal configuration. It acts as a lightweight wrapper around common web technologies like Express (for HTTP servers), XHRs (for HTTP clients), and WebSockets. The current stable version is 2.0.1. It provides a straightforward way to define server-side methods (both standard and WebSocket-specific) that are then exposed to a client-side API. A key differentiator is its emphasis on simplicity and low boilerplate, allowing developers to quickly set up RPC communication without diving into complex protocols. It strictly uses JSON as the transport format, meaning all arguments and return values must be JSON-serializable. Client-side usage relies on browser globals such as `XMLHttpRequest`, `WebSocket`, `btoa`, and `Promise`. The library does not specify a strict release cadence but provides a functional abstraction over underlying network primitives.
