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.

Scalpel is a web scraping library inspired by libraries like Parsec and Perl's Web::Scraper. Scalpel builds on top of TagSoup to provide a declarative and monadic interface.

This library provides basic WAI handlers and middleware functionality.

Gives you the tools to build parsers to decode JSON values, and gives good error messages when parsing fails. See also http://harry.garrood.me/blog/aeson-better-errors/.

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

This library provides basic MIME type handling types and functions.

This package provides generic HTTP types for Haskell (for both client and server code).

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

aeson-qq provides a JSON quasiquoter for Haskell. This package exposes the function aesonQQ that compile-time converts a string representation of a JSON value into a Data.Aeson.Value.

HTTP multipart split out of the cgi package, for Haskell.

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

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 Haskell library contains functions for encoding bytestring builders for chunked Hypertext Transfer Protocol (HTTP) 1.1 transfers.

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

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/. The Snap HTTP server is a high performance web server library written in Haskell. Together with the snap-core library upon which it depends, it provides a clean and efficient Haskell programming interface to the HTTP protocol.

This web server promotes a function from Request to IO Response into a local web server. The user can decide how to interpret the requests, and the library is intended for implementing Ajax APIs.

This package provides a simple network runner library in Haskell.

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

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.

The modules provided by this package contain predicates for Unicode blocks and char properties and character predicates defined by XML. The supported Unicode version is 7.0.0

libcurl is a versatile client-side URL transfer library. This package provides a Haskell binding to libcurl.

This package provides a backend for the http-client package using the connection and TLS libraries. It is intended for use by higher-level libraries, such as http-conduit.

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

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.
