POP3 Client for Node.js

Node-pop3 is a JavaScript client library for the Post Office Protocol version 3 (POP3), designed for use in Node.js environments. It provides functionalities to connect to POP3 servers, authenticate users, list messages, retrieve mail content, and manage mailboxes. The library supports both Promise-based asynchronous operations for cleaner code and Node.js Streams for efficient handling of potentially large mail bodies. Version `0.11.0` is the current stable release, requiring Node.js `^20.11.0 || >= 22.0.0`. It ships with TypeScript type definitions, enhancing development experience for TypeScript users. Key differentiators include its explicit support for modern JavaScript constructs like Promises and Streams, along with a simple command-line interface (CLI) for testing. While similar libraries exist, node-pop3 aims for a direct API mirroring the POP3 protocol, rather than a high-level abstraction.
