Provide a minimal servant-server project as a template

[soenkehahn]

This should live in its own github repo and probably include:

• cabal file,
• stack file,
• src directory with a minimal API and a server,
• test directory with a minimal test-suite using either servant-client or hspec-wai.

[alpmestan]

Great idea.

[rvion]

yes, and it would be great to have it either

• submitted to stack-templates.
• compatible with stack templates by pointing stack new to use servant repo as template catalog repo

[alexanderkjeldaas]

There is already some support in stack-templates now:

commercialhaskell/stack-templates@bd7b20e

What's nice about that template is that it enables letsencrypt.org by default.

Maybe this work could be merged with that template.

@alexanderkjeldaas interesting. Maybe a bit offtopic. but why choose to put nginx in front of the app instead of letting warp use the letsencrypt cert directly?

[alexanderkjeldaas]

The nginx docker container has an existing sidecar for letsencrypt.

I also think it is a bad idea not to have a HTTP load balancer in front of a backend in any production setup, and SSL termination has to happen at the load balancer.

I've opened this PR: commercialhaskell/stack-templates#52
It's for servant-0.4 since stack new doesn't support templates with stack files in it. (See a discussion here: https://groups.google.com/d/topic/haskell-stack/sOI5rY28G3E/discussion)

Once servant-0.5 is on stackage, we can of course update the template. (commercialhaskell/stackage#1290)

[soenkehahn]

I've created an example project here: https://github.com/haskell-servant/example-servant-minimal

[soenkehahn]

I also created a section about example projects in the documentation: #471. If we merge this, I would consider this issue solved.

Closing since #471 had been merged.
