IMAPFlow Client

ImapFlow is a modern, promise-based IMAP client library for Node.js, designed to simplify interactions with IMAP servers without requiring deep protocol knowledge. It provides an async/await API, automatically handles various IMAP extensions (like CONDSTORE, QRESYNC, IDLE, COMPRESS), and supports message streaming, mailbox locking, and proxy configurations. The current stable version is `1.3.2`. Releases appear to be frequent, with multiple patch and minor versions released monthly, indicating active development and maintenance. Key differentiators include its automatic IMAP extension handling, built-in mailbox locking for concurrent access, and comprehensive TypeScript support, making it robust for complex email processing applications. It also features specific support for Gmail labels and raw search queries via X-GM-EXT-1.
