Limited Request Queue

A Node.js queue library for interactively managing concurrency and rate limiting of outbound HTTP requests. Version 5.1.0 stable, with a maintenance-focused release cadence. Key differentiators: per-host concurrency limiting via URL host grouping, pause/resume at any time, simple EventEmitter-based API, and options to ignore ports, protocols, and subdomains for host grouping. Unlike generic async queues, it is specifically designed for outbound requests with host-aware throttling.
