README
WAI Lambda - Haskell Webapps on AWS Lambda
This Haskell library turns any wai webapp (spock, servant, etc) into a handler for AWS Lambda and API Gateway requests.
{-# LANGUAGE OverloadedStrings #-}
import Network.Wai
import Network.HTTP.Types
import Network.Wai.Handler.Lambda (run)
app :: Application
app _ respond = do
putStrLn "I've done some IO here"
respond $ responseLBS
status200
[("Content-Type", "text/plain")]
"Hello, Web!"
main :: IO ()
main = run app
This doesn't require any particular Lambda environment. By following the
instructions in the build section the resulting zip file uploaded
to AWS Lambda is typically smaller than 1MB. For basic webapps the request
handling duration (as reported by AWS) is between 1 and 5 milliseconds.
- Install with either Cabal, stack or Nix.
- Build for AWS with Nix and fully static executables.
- Deploy to AWS with Nix and Terraform.
Install
Cabal
Installing with Cabal:
$ cabal install wai-lambda
Stack
If you use stack and wai-lambda is not included in your snapshot, add it to
the extra-deps:
extra-deps:
- wai-lambda-0.1.0.0
or from GitHub:
packages:
- ...
- location:
git: https://github.com/deckgo/wai-lambda.git
commit: <some commit>
extra-dep: true
Nix
You do not have to do anything if you use cabal2nix and a Nix commit that
includes wai-lambda in its Hackage dependencies. If you want to use a
specific commit of wai-lambda we recommend using niv:
$ niv add deckgo/wai-lambda
Then add an override to your Nix packages:
rec
{
sources = import ./nix/sources.nix; # from niv
pkgs = import sources.nixpkgs {};
myHaskellPackages = pkgs.haskellPackages.override
{ overrides = self: super:
{ "wai-lambda" =
super.callCabal2nix "wai-lambda" sources.wai-lambda;
};
};
}
See also the build section for producing AWS Lambda packages with nix.
