Seq Logging for JavaScript

seq-logging is a JavaScript library designed to send structured log events to the Seq HTTP ingestion API. It is currently at version 3.0.0 and serves as a low-level client, primarily intended for use by other logging frameworks and their respective Seq transports (e.g., winston-seq, pino-seq, bunyan-seq, @tsed/logger-seq), rather than for direct application interaction. The library handles asynchronous batching of log events based on payload size and provides mechanisms to ensure all buffered events are sent upon application exit or explicit flushing. Its key differentiator is acting as the foundational communication layer for Seq within the JavaScript ecosystem, offering both Node.js and browser-specific builds, and explicitly supports ESM.
