The HTTP package supports client-side web programming in Haskell. It lets you set up HTTP connections, transmitting requests and processing the responses coming back.

Scalpel core provides a subset of the scalpel web scraping library that is intended to have lightweight dependencies and to be free of all non-Haskell dependencies.

This package provides an HTTP client engine, intended as a base layer for more user-friendly packages.

This package provides a library for the Web Distributed Authoring and Versioning (WebDAV) extensions to HTTP as well an executable, hdav, for command-line operation.

Snap is a simple and fast web development framework and server written in Haskell. For more information, you can visit the Snap project website at http://snapframework.com/. This library contains the core definitions and types for the Snap framework.

Haskell library which exposes zero-copy sendfile functionality in a portable way.

This package provides data streaming abstraction for Haskell's Web Application Interface (WAI).

Happstack Server provides an HTTP server and a rich set of functions for routing requests, handling query parameters, generating responses, working with cookies, serving files, and more.

This package's main goal is to encourage integration and system testing of web applications by making everything easy to test. Tests are like browser sessions that keep track of cookies and the last visited page. You can perform assertions on the content of HTML responses using CSS selectors.

This package handles cross-platform Web browser launching and inserts JavaScript code to ping the server. When the server no longer receives pings, it shuts down.

Parses Javascript into an Abstract Syntax Tree (AST). Initially intended as frontend to hjsmin.

Use websockets with WAI applications, primarily those hosted via Warp.

This library provides HTML combinators for Haskell.

Warp is a server library for HTTP/1.x and HTTP/2 based WAI (Web Application Interface in Haskell).

An HTTP client using the Snap Framework's io-streams library to handle the streaming IO. The API is optimized for ease of use for the rather common case of code needing to query web services and deal with the result.

This package contains a combinator library for constructing HTML documents.

This package bundles the minified jQuery code into a Haskell package, so it can be depended upon by Cabal packages. The first three components of the version number match the upstream jQuery version. The package is designed to meet the redistribution requirements of downstream users (e.g. Debian).

Skein is a family of fast secure cryptographic hash functions designed by Niels Ferguson, Stefan Lucks, Bruce Schneier, Doug Whiting, Mihir Bellare, Tadayoshi Kohno, Jon Callas and Jesse Walker.

This Haskell package uses bindings to the optimized C implementation of Skein.

Sourcemap provides an implementation of source maps, revision 3, proposed by Google and Mozilla here https://wiki.mozilla.org/DevTools/Features/SourceMap.

This Haskell package provides two typeclasses for converting Haskell data types to and from route pieces.

TagSoup is a library for parsing HTML/XML. It supports the HTML 5 specification, and can be used to parse either well-formed XML, or unstructured and malformed HTML from the web. The library also provides useful functions to extract information from an HTML document, making it ideal for screen-scraping.

This package provides a HTTP/2.0 library including frames and HPACK. Currently HTTP/2 16 framing and HPACK 10 is supported.

This package provides a library providing QuickCheck for the mattermost-api library to allow testing. This is provided as a separate library to allow use of the API library without testing dependencies.

This library supports full W3C XML Schema regular expressions inclusive all Unicode character sets and blocks. It is implemented by the technique of derivations of regular expressions.
