Module documentation for 0.14.0.6
Snap is a simple and fast web development framework and server written in
Haskell. For more information about Snap, read the
README.SNAP.md or visit
the Snap project website at http://www.snapframework.com/.
This is top-level project for the Snap Framework, which contains:
a library allowing Snap applications to recompile actions on the fly in development mode, with no performance loss in production mode.
a "snaplet" API allowing web applications to be build from composable pieces.
The command-line utility
snap for creating initial Snap applications used to
be a part of this package. As of version 1.0, the snap command-line utility is
no longer provided by this package. It is now provided by the package
After you clone the repository, change to the newly created snap directory and run
git submodule update --init --recursive ./init-sandbox.sh cabal install
(You may want to look at pull.sh or pullLatestMaster.sh.) This updates all the Snap Framework dependencies to the correct version, creates a sandbox, and installs everything. The snap library is built using Cabal and Hackage.
Building the Haddock Documentation
The haddock documentation can be built using 'cabal haddock'.
The docs get put in
Building the testsuite
To build the test suite, run
$ cabal clean $ cabal configure --enable-tests --enable-library-coverage $ cabal build $ cabal install --enable-tests
From here you can invoke the testsuite by running:
The testsuite generates an
hpc test coverage report in

- Generate and read the haddock docs.
- The test code has the nice property that it actually functions as a pretty good example app and covers a lot of the use cases.
- If you're interested in the implementation, read design.md.
