import Web.Spock

import qualified Data.Text as T

main =
    runSpock 3000 $ spockT id $
    do get ("echo" <//> var) $ \something ->
        text $ T.concat ["Echo: ", something]

Features

Another Haskell web framework for rapid development: This toolbox provides everything you need to get a quick start into web hacking with haskell:

• fast typesafe routing
• middleware
• json
• sessions
• cookies
• database helper
• csrf-protection
• typesafe contexts

Extensions

The following Spock extensions exist:

• Background workers for Spock: Spock-worker
• Digestive functors for Spock: Spock-digestive

Works well with Spock

• User management users
• Data validation validate-input
• Blaze bootstrap helpers blaze-bootstrap
• digestive-forms bootstrap helpers digestive-bootstrap

SSL / HTTPS

If you’d like to use your application via HTTPS, there are two options:

• Use nginx/haproxy/… as reverse proxy in front of the Spock application.
• Convert the Spock application to a wai-application using the spockAsApp. Then use the warp-tls package to run it.

Benchmarks

See the Spock-bench repository to reproduce.

Example Projects

• funblog
• makeci
• curry-recipes

Notes

Since version 0.11.0.0 Spock drops simple routing in favor of typesafe routing and drops safe actions in favor of the “usual” way of csrf protection with a token.

Since version 0.7.0.0 Spock supports typesafe routing. If you wish to continue using the untyped version of Spock you can Use Web.Spock.Simple. The implementation of the routing is implemented in a separate haskell package called reroute.

Since version 0.5.0.0 Spock is no longer built on top of scotty. The design and interface is still influenced by scotty, but the internal implementation differs from scotty’s.

Thanks to

• Tim Baumann Github (lot’s of help with typesafe routing)
• Tom Nielsen Github (much feedback and small improvements)
