Bidirectional Channel for JavaScript

BIDC is a JavaScript library designed for establishing robust, asynchronous, bidirectional communication channels between different JavaScript execution contexts, such as web workers, iframes, and service workers. Unlike traditional `postMessage` APIs, BIDC abstracts away the complexities of message passing, providing full support for promises, async functions, and a wide range of complex data types (e.g., Date, RegExp, Map, Set, ArrayBuffer). It features an automatic handshake mechanism to establish and re-establish connections seamlessly, even if one side reloads, and buffers messages until the recipient is ready. Currently at version 0.0.4, the library is in an early development stage, focusing on foundational features for secure and efficient cross-context communication. Its primary differentiators are automatic connection management, comprehensive data type serialization, and first-class async/await support, streamlining RPC-style interactions. It ships with TypeScript types, enhancing developer experience and type safety.
