PostgreSQL for Javascript

This library is a implementation of the PostgreSQL backend/frontend protocol in javascript. It uses the node.js tcp and event libraries. A javascript md5 library is included for servers that require md5 password hashing (this is default).

This library also allows for the handling of prepared queries and parameterized queries.

Example use

var sys = require("sys");
var Postgres = require("./postgres");

Postgres.DEBUG= 1;

var db = new Postgres.Connection("database", "username", "password");

var promise = db.query("SELECT * FROM test");

promise.addCallback(function (data) {
  sys.p(data);
});

promise.addErrback(function (error_message) {
	sys.debug(error_message);
});

db.close();

Example use of Parameterized Queries

var sys = require("sys");
var pg = require("postgres.js");

var db = new pg.Connection("database", "username", "password");
db.query("SELECT * FROM yourtable WHERE id = ?", [1]).addCallback(function (data) {
    
    sys.p(data);
});
db.close();

Example use of Prepared Queries

var sys = require("sys");
var pg = require("postgres.js");

var db = new pg.Connection("database", "username", "password");

db.prepare("SELECT * FROM yourtable WHERE id = ?").addCallback(function (query) {

    sys.p(query);
    query.execute(["1"]).addCallback(function (d) {
        sys.p(d);
    });
    /* More queries here. */
});
db.close();
