Open Source Dart HTTP Servers

Shelf makes it easy to create and compose web servers and parts of web servers. How? Expose a small set of simple types. Map server logic into a simple function: a single argument for the request, the response is the return value. Trivially mix and match synchronous and asynchronous processing. Flexibility to return a simple string or a byte stream with the same model. An adapter must handle all errors from the handler, including the handler returning a null response. It should print each error to the console if possible, then act as though the handler returned a 500 response. The adapter may include body data for the 500 response, but this body data must not include information about the error that occurred. This ensures that unexpected errors don't result in exposing internal information in production by default; if the user wants to return detailed error descriptions, they should explicitly include middleware to do so.

A composable, Future-based library for making HTTP requests. This package contains a set of high-level functions and classes that make it easy to consume HTTP resources. It's multi-platform and supports mobile, desktop, and browser. The easiest way to use this library is via the top-level functions. They allow you to make individual HTTP requests with minimal hassle. If you're making multiple requests to the same server, you can keep open a persistent connection by using a Client rather than making one-off requests. You can also exert more fine-grained control over your requests and responses by creating Request or StreamedRequest objects yourself and passing them to Client.send. This package is designed to be composable. This makes it easy for external libraries to work with one another to add behavior to it. Libraries wishing to add behavior should create a subclass of BaseClient that wraps another Client and adds the desired behavior.
