Unfetch
unfetch 是一个同构 HTTP 客户端和网络库，提供了一个基于 Promise 的接口，用于在浏览器和服务器环境中一致地执行网络请求。它作为 Fetch API 的轻量级实现，适用于缺乏原生网络请求支持的环境。
该库支持以文本、JSON 或二进制 Blob 的形式检索 Web 资源，同时保持较小的内存占用。它通过在原生浏览器支持不可用时将 fetch 接口安装到全局命名空间中来充当 Polyfill。
该工具涵盖了广泛的 Web 资源检索功能，包括执行 HTTP 请求、检查响应头和解析响应内容的能力。
Features
- Isomorphic HTTP Clients - Implements a promise-based interface for performing network requests consistently across both browser and server environments.
- Fetch Polyfills - Implements the official web fetch specification to provide a consistent API across legacy and modern environments.
- Metric Data URL Fetches - Retrieves web resources using asynchronous promises with configurable methods, headers, and bodies.
- Request Execution - Executes HTTP requests by switching between different implementation drivers based on the runtime environment.
- HTTP Request Execution - Performs standard synchronous and asynchronous HTTP operations across both browser and server environments.
- Isomorphic - Routes network calls to the appropriate underlying driver based on whether the code is running in a browser or server.
- Network Implementation Switching - Switches between native browser APIs and server-side network modules depending on the detected execution runtime.
- Promise-Based HTTP Clients - Provides a promise-based interface for making asynchronous network requests consistently across multiple platforms.
- Promise-Based API Wrappers - Wraps asynchronous network operations in promises to provide a standardized interface for request and response cycles.
- Cross-Environment Polyfills - Provides an abstract networking layer that allows the same API to function identically in Node.js and browser environments.
- Isomorphic Networking Libraries - Provides a compact tool for retrieving web resources as text, JSON, or binary blobs across different environments.
- Network Resource Retrievals - Retrieves web resources using asynchronous promises that resolve into standardized response objects.
- Response Body Parsing - Provides utilities to convert raw network response payloads into structured formats such as JSON, text, or binary blobs.
- Response Header Extractors - Extracts header keys and values from network responses to verify metadata and server instructions.
- Global - Attaches the fetch implementation to the global object to ensure compatibility with code expecting a native API.
- Networking Libraries - Offers a minimalist implementation for executing HTTP requests and parsing responses with a small memory footprint.
- API Layer - Lightweight fetch polyfill for older environments.
