Description

Heroku-style database connection URL parsing.

Synopsis

Documentation

data DBConnection Source

A type representing the information that can be parsed from a URL-style database configuration. For example consider the following URLs

 postgres://user3123:passkja83kd8@ec2-117-21-174-214.compute-1.amazonaws.com:6212/db982398
 mysql://adffdadf2341:adf4234@us-cdbr-east.cleardb.com/heroku_db?reconnect=true
 mysql2://adffdadf2341:adf4234@us-cdbr-east.cleardb.com/heroku_db?reconnect=true
 http://user:pass@instance.ip/resourceid
 amqp://user:pass@ec2.clustername.cloudamqp.com/vhost

We assume that all the information in these URLs is provided---if a username or password is unnecessary then it must be passed as an empty string and not omitted.

Constructors

Fields provider :: Provider host :: ByteString username :: ByteString password :: ByteString port :: Int location :: ByteString params :: Map ByteString ByteString

Instances

FromEnv DBConnection

data Provider Source

Provider indicates what kind of database provider scheme this URL refers to. This provides a small amount of convenience around URL detection, but if detection fails use providerName to extract the raw string.

Postgres ByteString
MySQL ByteString
AMQP ByteString
HTTP ByteString
