Level 01

The purpose of this exercise is to whet our appetite by creating a basic web app. The focus will be on reading the Hackage documentation for the Wai framework. Consult the src/FirstApp/Main.hs to find the parts that are missing and what we need from the Wai package to build our "Hello, World!" application.

Our "application" will respond to ALL incoming requests with a 200 status code response and the message "Hello, World!".

Running the program

To run the application:

# With Cabal
$ cabal run level01-exe

# With Stack
$ stack exec level01-exe

Accessing the program

# Using curl
$ curl -XGET localhost:<port number>

You can also use a browser and go to http://localhost:<port number>.
