The Yesod team strongly recommends using the stack build tool for developing with stack. There are other build tools available in the Haskell world which will likely work with Yesod, but stack provides the easiest experience. To get started:

  1. Follow the installation instructions for stack to get stack.
  2. Create a new scaffolded site: stack new my-project yesod-sqlite && cd my-project
    • NOTE: Use stack templates to see other available Yesod scaffoldings.
  3. Install the yesod command line tool: stack install yesod-bin cabal-install --install-ghc
  4. Build libraries: stack build
  5. Launch devel server: stack exec -- yesod devel
  6. View your Yesod site at http://localhost:3000/

NOTE: If you get an error message about GHC_PACKAGE_PATH at step (5), you need to install a newer version of yesod-bin. Try running stack install yesod-bin-1.4.11 and rerunning stack exec -- yesod devel. Also, if you choose the "mini" scaffolding, yesod devel will not work.

System libraries

Note that you will need the dev version of some system libraries to be available for the above steps to work. For example, on Ubuntu, you may need to run something like:

sudo apt-get install -y build-essential zlib1g-dev

If you're using a database, you'll likely need to install the system libraries to talk to it. Some Ubuntu examples are:

sudo apt-get install -y libmysqlclient-dev
sudo apt-get install -y libpq-dev
