Get-It is a composable HTTP request library for Node.js (>= 14) and modern browsers, designed to provide a small bundle footprint while offering a flexible middleware-based approach. It supports promise, observable, and low-level event-emitter patterns, with features like automatic JSON parsing/stringifying, retry logic, cancellation, timeouts, and progress events, making it ideal for developers who need a lightweight, cross-platform HTTP client that can be tailored to specific project requirements.
