    AIOHTTP

    AIOHTTP

    Asynchronous HTTP client/server framework for asyncio and Python

    Asynchronous HTTP Client/Server for asyncio and Python. AIOHTTP supports both client and server side of HTTP protocol. A long awaited new feature is tracing client request life cycle to figure out when and why client request spends a time waiting for connection establishment, getting server response headers etc. Now it is possible by registering special signal handlers on every request processing stage. The main change is dropping yield from support and using async/await everywhere. Farewell, Python 3.4. You often want to send some sort of data in the URL’s query string. If you were constructing the URL by hand, this data would be given as key/value pairs in the URL after a question mark, e.g. httpbin.org/get?key=val. Requests allows you to provide these arguments as a dict, using the params keyword argument. aiohttp internally performs URL canonicalization before sending request.

    Rouille

    Rouille

    Web framework in Rust

    Rouille is a micro-web-framework library. It creates a listening socket and parses incoming HTTP requests from clients, then gives you the hand to process the request. Rouille was designed to be intuitive to use if you know Rust. Contrary to express-like frameworks, it doesn't employ middlewares. Instead, everything is handled in a linear way. Concepts closely related to websites (like cookies, CGI, form input, etc.) are directly supported by rouille. More general concepts (like database handling or templating) are not directly handled, as they are considered orthogonal to the microweb framework. However, rouille's design makes it easy to use in conjunction with any third-party library without the need for any glue code. The rouille library just ignores this optimization and focuses on providing an easy-to-use synchronous API instead, where each request is handled in its own dedicated thread.

    Takes

    Takes

    True object-oriented Java web framework without NULLs

    Takes is a true object-oriented and immutable Java8 web development framework. Pay attention that UTF-8 encoding is set on the command line. The entire framework relies on your default Java encoding, which is not necessarily UTF-8 by default. To be sure, always set it on the command line with file.encoding Java argument. We decided not to hard-code "UTF-8" in our code mostly because this would be against the entire idea of Java localization, according to which a user always should have a choice of encoding and language selection. We're using Charset.defaultCharset() everywhere in the code. Essential part of Bigger Example is Front interface. It's encapsulates server's back-end and used to start an instance, which will accept requests and return results. FtBasic, which is a basic front, implements that interface.
