Popsicle HTTP Client

Popsicle is an advanced HTTP client library designed for both Node.js and browser environments, currently stable at version 12.1.2. It provides a fetch-like API, built upon the `Servie` request and response interfaces, offering a universal solution without requiring environment-specific configuration by default. Releases typically involve patch updates for bug fixes and dependency management, with major versions introducing significant architectural changes, such as the `Servie 4` migration in v12.0.0. Key differentiators include its modular middleware architecture, which allows for extensive customization, and its optimized bundles for different environments. Node.js environments benefit from built-in features like User-Agent handling, content encoding decoding, redirect following, and an in-memory cookie cache, while browser builds are lighter, focusing solely on the `XMLHttpRequest` transport layer. This design allows developers to compose functionality and create highly tailored HTTP clients.
