Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

seneca-oracle-store

Seneca node.js data-storage plugin for Oracle.

This module is a plugin for the Seneca framework. It provides a storage engine that uses Oracle to persist data. This module is for production use.

The Seneca framework provides an ActiveRecord-style data storage API. Each supported database has a plugin, such as this one, that provides the underlying Seneca plugin actions required for data persistence.

Support

If you're using this module, feel free to contact me on twitter if you have any questions! :) @paolochiodi

Current Version: 0.1.2

Tested on: Node 0.10.29, Seneca 0.5.19

Quick example

var seneca = require('seneca')()
seneca.use('oracle-store',{
  hostname: "localhost",
  port: 1521,
  database: "xe", // System ID (SID)
  user: "oracle",
  password: "oracle"
})

seneca.ready(function(){
  var apple = seneca.make$('fruit')
  apple.name  = 'Pink Lady'
  apple.price = 0.99
  apple.save$(function(err,apple){
    console.log( "apple.id = "+apple.id  )
  })
})

Note: this module support connecting to oracle databases with tns strings. For more information, checkout the oracle module

Install

npm install seneca
npm install seneca-oracle-store

Note: seneca-oracle-store depends on module oracle to connect to oracle databases. In order to compile and install the oracle module you should have installed oracle instanst client and its sdk. Fore more information see the oracle module docs on installation

Usage

You don't use this module directly. It provides an underlying data storage engine for the Seneca entity API:

var entity = seneca.make$('typename')
entity.someproperty = "something"
entity.anotherproperty = 100

entity.save$( function(err,entity){ ... } )
entity.load$( {id: ...}, function(err,entity){ ... } )
entity.list$( {property: ...}, function(err,entity){ ... } )
entity.remove$( {id: ...}, function(err,entity){ ... } )

Queries

The standard Seneca query format is supported:

  • entity.list$({field1:value1, field2:value2, ...}) implies pseudo-query field1==value1 AND field2==value2, ...
  • you can only do AND queries. That's all folks. Ya'll can go home now. The Fat Lady has sung.
  • entity.list$({f1:v1,...,sort$:{field1:1}}) means sort by field1, ascending
  • entity.list$({f1:v1,...,sort$:{field1:-1}}) means sort by field1, descending
  • entity.list$({f1:v1,...,limit$:10}) means only return 10 results
  • entity.list$({f1:v1,...,skip$:5}) means skip the first 5
  • entity.list$({f1:v1,...,fields$:['field1','field2']}) means only return the listed fields (avoids pulling lots of data out of the database)
  • you can use sort$, limit$, skip$ and fields$ together

Native Driver

As with all seneca stores, you can access the native driver, in this case, the node-oracle connection object using entity.native$(function(err,connectio){...}).

How to write a SQL query using node-oracle driver:

var query = 'SELECT * FROM "orders WHERE "cust_id"=:1 AND "total" > :2';

orders_ent.native$(function(err, connection){
  connection.execute(query, ['customer', 1000], function(err, list) {
    if(err) return done(err);
    console.log("Found records:", list);
  });
}); // end native$

Note on table and column names

With Oracle, unquoted table and column names are case insensitive and treated as upper case. In order to consistently retrieve entity property names from database oracle-store quotes all names, meaning that you should quote names when creating tables and columns and use name whose case match exactly the entity property names.

Unsupported features

At the moment there is no support for:

  • connection pool

Test

See the test README

TODO

  • add connection pool
