db-pool

db-pool

Easily create a Postgres/MySQL connection pool (postgres only until I get MariaDB/MySQL working on my new Ubuntu 13.04 dev machine).

Behind the scenes it returns an any-db pool which can be used as described here.

Getting Started

Install the module with: npm install db-pool

Configuration

Create a config/database.js containing something like

exports.app1 = {
  defaults: {
    driver: 'postgres',
    min: 5,
    max: 20
  },
  development: {
    database: "development",
    username: "username",
    password: "pass"
  },
  production: {
    database: "production",
    username: "username",
    password: "pass",
    port: 9999
  },
  test: {
    database: "test",
    username: "username",
    password: "pass",
    host: "some.hostname",
    min: 15
  }
};

exports.app1 = {
  ...
  ...
}

Example

var db_pool = require('db-pool');

// Optionally specify an alternative config file (default is to use /config/database.js)
db_pool.config('/config/custom-db-config-file.js');

// Create the default pool (from app1) using NODE_ENV=development|test|production
var test = db_pool.pool();

// Create a pool to a development database
var dev = db_pool.pool('development');
var app1_dev = db_pool.pool('app1.development');

// Create another pool to a different database
var test = db_pool.pool('test');

// Show the known connections. Active ones have pool, connStr and merged default attributes.
console.log(db_pool.debug());

// Run a query
dev.query("SELECT 1", function (err, results) {
  console.log(results);

  // Terminate all active pools
  db_pool.closeAll();
})
