pg-objects

Dependencies

npm install pg

Installation

npm install pg-objects

Quickstart

pg-objects exposes a couple of helper methods for using JS objects with pg queries. This is a very simple implementation, but one that has worked for me. So far.

var pg = require('pg')
  , pgobj = require('pg-objects')
  ;

pg.connect(connectionString, function(err, client) {

  if (err) throw err;

  var prepped = pgobj.insert({ email: 'yums@tasty.com', password: 'apassword' });

  client.query(
    "INSERT INTO users (" + prepped.fields + ") VALUES (" + prepped.params + ")",
    // "INSERT INTO users (email, password) VALUES ($1, $2)"

    prepped.values,
    // ['yums@tasty.com', 'apassword']

    function(err, result) {
      // Your logic.
    }
  );

});

Methods

  • insert
  • update
  • hash

insert

var prepped = pgobj.insert({ email: 'yums@tasty.com', password: 'apassword' });

client.query(
  "INSERT INTO users (" + prepped.fields + ") VALUES (" + prepped.params + ")",
  // "INSERT INTO users (email, password) VALUES ($1, $2)"

  prepped.values,
  // ['yums@tasty.com', 'apassword']

update

var prepped = pgobj.update({ password: 'newpassword', lastactive: new Date() });

client.query(
  "UPDATE users SET " + prepped.fields,
  // "UPDATE users SET password=$1, lastactive=$2"

  prepped.values,
  // ['newpassword', *a Date value*]

hash(string [, salt [, hash]])

Each parameter is of type String.

Caveat

pgobj.(insert/update).fields is NOT character escaped so ensure that your object keys are safe!
