Database Setup

After installing Postgres, run:

createuser stake --password stake --superuser
createdb stake
createdb stake_test

Haskell Setup

1. If you haven't already, install Stack
   • On POSIX systems, this is usually curl -sSL https://get.haskellstack.org/ | sh
2. Install the yesod command line tool: stack install yesod-bin --install-ghc
3. Build libraries: stack build

If you have trouble, refer to the Yesod Quickstart guide for additional detail.

Development

Start a development server with:

stack exec -- yesod devel

As your code changes, your site will be automatically recompiled and redeployed to localhost.

Tests

stack test --flag stake:library-only --flag stake:dev

(Because yesod devel passes the library-only and dev flags, matching those flags means you don't need to recompile between tests and development, and it disables optimization to speed up your test compile times).

Documentation

• Read the Yesod Book online for free
• Check Stackage for documentation on the packages in your LTS Haskell version, or search it using Hoogle. Tip: Your LTS version is in your stack.yaml file.
• For local documentation, use:
  • stack haddock --open to generate Haddock documentation for your dependencies, and open that documentation in a browser
  • stack hoogle <function, module or type signature> to generate a Hoogle database and search for your query
• The Yesod cookbook has sample code for various needs

Getting Help

• Ask questions on Stack Overflow, using the Yesod or Haskell tags
• Ask the Yesod Google Group
• There are several chatrooms you can ask for help:
  • For IRC, try Freenode#yesod and Freenode#haskell
  • Functional Programming Slack, in the #haskell, #haskell-beginners, or #yesod channels.
