factorial-server

Small demos (factorial) for use of the snap framework, part of the UU AFP summerschool lecture on web programming.

Installation & running

Build using cabal. Location of executables is mentioned by cabal build. The following factorial server variants are built:

• factorial-server-0hw: a hello world minimal server
• factorial-server-1html: rendering via blaze html
• factorial-server-2heist: rendering via snap+heist, digestive functor forms
• factorial-server-3acid: same as 2heist but with persistency via acid

Then run by (e.g.):

• .cabal-sandbox/bin/factorial-server-0hw -p 8000
• open a browser at http://localhost:8000 (let url of this be called the SERVER)

In the browser, for

• factorial-server-0hw
  • SERVER, the static factorial result
• factorial-server-1html
  • SERVER/factorial/nr, the factorial of nr, in plain text
  • SERVER/factorial2/nr, the factorial of nr, in html text
  • SERVER/factorial3/nr, the factorial of nr, in html page (with body tag etc)
  • SERVER/factorial4/nr, the factorial of nr, in html page with table
• factorial-server-2heist
  • SERVER/factorial/nr, the factorial of nr, html created via heist template
  • SERVER/factorial2, nr entered & displayed via digestive form
• factorial-server-3acid
  • SERVER/factorial, nr entered & displayed via digestive form, remembered persistently
