#node-postgres
Non-blocking (async) pure JavaScript PostgreSQL client for node.js written
with love and TDD.
## alpha version
### Installation
npm install pg
### Example
var pg = require('pg');
pg.connect('postgres://user:password@host:port/database', function(error, client) {
if(error) {
//handle error
return
}
//simple query
client.query("CREATE TABLE users(name varchar(10), birthday timestamptz)")
//prepared statements with bound parameters
client.query("INSERT INTO users(name, birthday) VALUES($1, $2)" ['brianc', new Date(2010, 01, 01)])
client.query("INSERT INTO users(name, birthday) VALUES($1, $2)", ['ringo', new Date(2008, 01, 01)])
client.query("SELECT * FROM users WHERE birthday > $1", [new Date(2009, 01, 01)], function(error, result) {
if(error) {
//handle error
return
}
var user = result.rows[0]
console.log(user.name) //brianc
console.log(user.birthday.getYear()) //2010
})
})
### Philosophy
* well tested
* no monkey patching
* no dependencies (...besides PostgreSQL)
* [extreme documentation](http://github.com/brianc/node-postgres/wiki)
### features
- prepared statement support
- parameters
- query caching
- type coercion
- date <-> timestamptz
- integer <-> integer, smallint, bigint
- float <-> double, numeric
- boolean <-> boolean
- notification message support
- tested like a Toyota

## More info please
### Documentation
__PLEASE__ check out the [WIKI](node-postgres/wiki). __MUCH__ more information there.
### Working?
[this page](http://www.explodemy.com) is running the worlds worst (but fully functional) PostgreSQL backed, Node.js powered website.
### Why did you write this?
As soon as I saw node.js for the first time I knew I had found
something lovely and simple and _just what I always wanted!_. So...I
poked around for a while. I was excited. I still am!
I drew major inspiration from [postgres-js](http://github.com/creationix/postgres-js).
I also drew some major inspirrado from
[node-mysql](http://github.com/felixge/node-mysql) and liked what I
saw there.
### Plans for the future?
- transparent prepared statement caching
- connection pooling
- more testings of error scenarios
