Electrum Client

The package `electrum-client` (npm: `electrum-client`, GitHub: `you21979/node-electrum-client`) provides a Node.js client for interacting with ElectrumX servers using the Electrum protocol. It supports core functionalities like TCP/TLS connections, JSON-RPC method calls for querying blockchain data (e.g., server version), and EventEmitter for handling real-time subscription messages (e.g., blockchain headers). As of its latest version, 0.0.6, the package has not seen updates since its last publish date approximately eight years ago (February 2018), indicating an abandoned state. A key differentiator initially was its explicit lack of external dependencies. However, due to its age, developers should be aware that more actively maintained and feature-rich alternatives exist under similar names, such as `@samouraiwallet/electrum-client`, `@bitcoinerlab/electrum-client`, and `@mempool/electrum-client`, many of which offer ES Module compatibility and TypeScript support. The original `electrum-client` is strictly a CommonJS module.
