Intro

Hackage: Spock Tutorial: Spock Tutorial

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

• fast routing (both typesafe and "untyped")
• middleware
• json
• sessions
• cookies
• database helper
• csrf-protection

Benchmarks:

• https://github.com/philopon/apiary-benchmark
• https://github.com/agrafix/Spock-scotty-benchmark

Usage (Typesafe, recommended)

{-# LANGUAGE OverloadedStrings #-}
import Web.Spock

import qualified Data.Text as T

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

(read more at Type-safe routing in Spock)

Usage (Simple)

{-# LANGUAGE OverloadedStrings #-}
import Web.Spock.Simple

import qualified Data.Text as T

main =
    runSpock 3000 $ spockT id $
    do get ("echo" <//> ":something") $
        do Just something <- param "something"
           text $ T.concat ["Echo: ", something]
       get ("regex" <//> "{number:^[0-9]+$}") $
        do Just number <- param "number"
           text $ T.concat ["Just a number: ", number]

Install

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

Notes

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.
