pg-database-url

Build a database url from a config object



Installation

``
npm install pg-database-url --save
`

Usage

`js
var pgUrl = require('pg-database-url')

// Example config
// This may already be available from your database configuration or environment variables
var dbConfig = {
host: 'localhost',
port: 5432,
database: 'dbname',
username: 'user',
password: 'pass'
}

var connString = pgUrl(dbConfig)
// -> 'postgres://user:pass@localhost:5432/dbname'
`

You can then use the resulting connection string with a library like node-postgres to establish a database connection.

The minimum config object could look look like this:
`js
{
database: 'dbname',
username: 'user'
}
`
which assumes that the connection is on localhost:5432 and the database is configured to not require a password.

This would return a connection string like: 'postgres://user@localhost:5432/dbname'`
