Really basic wrapper for node-sqlite3
Of course, this is nowhere near done, so please suggest improvements and additions!
Installation
bower i -S purescript-node-sqlite3 && npm i -S sqlite3
Usage
launchAff do
conn <- newDB "./data"
exists <- (\rows -> 1 == length rows) <$> queryDB conn "SELECT 1 from foods where name = ?" ["gulerodskage-med-flødest"]
log $ "do we have this?: " <> (show exists)
closeDB conn
