In the Python ecosystem, <span>requests</span> has long been the preferred tool for HTTP clients. However, with the rise of asynchronous programming and HTTP/2, developers need a more modern and flexible solution. This is where <span>httpx</span> comes into play!
What is HTTPX?
<span>HTTPX</span> is a powerful and modern Python HTTP client library that supports both synchronous and asynchronous requests, with built-in HTTP/2 support. It offers an API similar to <span>requests</span>, but adds many new features, making it the preferred choice for the next generation of HTTP tools.
Main Features
-
Synchronous & Asynchronous Support:
-
Supports traditional synchronous requests and can seamlessly integrate
<span>async/await</span>for asynchronous operations. -
Compatible with
<span>asyncio</span>and<span>trio</span>and other asynchronous frameworks.
HTTP/2 Support:
-
Defaults to HTTP/1.1, with optional HTTP/2 support (requires installation of
<span>httpx[http2]</span>).
Faster Performance:
-
Compared to
<span>requests</span>,<span>httpx</span>performs better in connection reuse and asynchronous requests.
Type Annotation Friendly:
-
Fully compatible with Python’s type hints, facilitating static type checking.
Powerful Client Configuration:
-
Supports advanced features such as connection timeouts, proxies, cookie management, and authentication.
Compatible with <span>requests</span> API:
-
If you are familiar with
<span>requests</span>, you can almost painlessly migrate to<span>httpx</span>.
Installing HTTPX
Basic Usage

4. Using HTTP/2
Why Choose HTTPX over Requests?
| Feature | <span>httpx</span> |
<span>requests</span> |
|---|---|---|
| Asynchronous Support | ✅ | ❌ |
| HTTP/2 | ✅ | ❌ |
| Type Annotations | ✅ | ❌ |
| Connection Pool Optimization | ✅ | ⚠️ |
| Modern Code Design | ✅ | ❌ |
If your project requires high performance, asynchronous support, or HTTP/2, then <span>httpx</span> is undoubtedly the better choice!
Conclusion
<span>HTTPX</span> not only inherits the ease of use of <span>requests</span>, but also introduces many features required by modern HTTP clients. Whether for synchronous or asynchronous programming, it provides an excellent experience. If you haven’t tried <span>httpx</span>, now is the best time!
