Serve a RESTful API from any Postgres database

Installation

brew install postgres
cabal install -j --enable-tests

Example usage:

cabal run -p 3000 -d postgres://[auth-role]:@localhost:5432/[database] -a [anonymous-role]

You will need to provide two database roles (which are allowed to be the same). One is called the authenticator role (auth-role above) which should have enough privileges to read the auth table in the dbapi schema if you intend to support multi-user applications.

The other role is for anonymous access (anonymous-role above). Immediately upon acceping any unauthenticated HTTP connection dbapi assumes this role in its queries to postgres. Give this role as much or little permissions as you would like.

Running tests

createuser --superuser --no-password dbapi_test
createdb -O dbapi_test -U postgres dbapi_test

cabal test --show-details=always --test-options="--color"

Thanks to Adam Baker for code contributions and many fundamental design discussions. Also thanks to Loop/Recur for open-source Fridays to advance the code, and for their courage to use this thing in real projects.
