> A postgres interface layer for common requests. It uses [pg](https://github.com/brianc/node-postgres) to connect

and wraps it in a tiny layer using ES2015 promises with the goal to be simpler and compatible with [mssql](https://github.com/patriksimek/node-mssql)

via [mssql-cr-layer](https://github.com/andrglo/mssql-cr-layer)

## Install

```sh

$ npm install --save pg-cr-layer

```

## Usage

```js

var pgCrLayer = require('pg-cr-layer');

var config = {

  user: 'me',

  password: 'my password',

  host: 'localhost',

  port: 5432,

  pool: {

    max: 25,

    idleTimeout: 30000

  }

};

var layer = new PgCrLayer(config)

layer.connect()

  .then(function() {

    return layer.execute('CREATE TABLE products ( ' +

      'product_no integer, ' +

      'name varchar(10), ' +

      'price numeric(12,2) )');

  })

  .then(function() {

    return layer.transaction(function(t) {

      return layer

	      .execute('INSERT INTO products VALUES (1, \'Cheese\', 9.99)', null, {transaction: t})

          .then(function() {

            return layer.execute('INSERT INTO products VALUES (2, \'Chicken\', 19.99)', null, {transaction: t})

          })

		  .then(function() {

        return layer

          .execute('INSERT INTO products VALUES ($1, $2, $3)', [3, 'Duck', 0.99], {transaction: t})

       });

     })

  })

  .then(function() {

    return layer.query('SELECT * FROM products WHERE product_no=@product_no',

      {product_no: {value: 1, type: 'integer'}}) // or just {product_no: 1}

    .then(function(recordset) {

      console.log(recordset[0]); // => { product_no: 1, name: 'Cheese', price: '9.99' }

    })

  })

  .then(function() {

    return layer.close();

  })

  .catch(function(error) {

	  console.log(error);

  });

```
