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 🙏

Overview

Express-Cassandra is an advanced Cassandra ORM for NodeJS. No more hassling with raw cql queries from your nodejs web frameworks. Express-Cassandra automatically loads your models and provides you with object oriented mapping to your cassandra tables like a standard ORM. It's framework independent nature allows you to use it with many popular nodejs frameworks with ease.

  • supports the latest cassandra 3.x releases
  • most of the bleeding edge cassandra features are supported
  • compatible with datastax enterprise search and dse graph
  • full featured CRUD operations and data type validations
  • full support for collections and other advanced data types
  • support for materialized views, secondary/custom/sasi indexes
  • support for complex queries, streaming and token based pagination
  • support for user defined types/functions/aggregates
  • support for batching ORM operations for atomic updates
  • support for before and after hook functions for save/update/delete
  • built-in experimental support for automatic migrations
  • built-in promise support with Async suffixed functions

This module uses datastax dse-driver which is based on the official cassandra-driver for node. The dse driver is used so that both apache-cassandra and datastax enterprise users can use this module. Some of the base orm features are wrapper over a highly modified version of apollo-cassandra module. The modifications made to the orm library was necessary to support missing features in the orm, keep it updated with the latest cassandra releases and to make it compatible with the advanced requirements of this module.

Installation

For cassandra version 3.x

npm install express-cassandra

For older cassandra 2.x

npm install [email protected]

Please note that if you use the legacy cassandra 2.x compliant version then please use the corresponding README.md file for that version. The following documentation is for version 3.x only. The materialized view support and several other part of the documentation is strictly applicable for cassandra 3.x and will not work in earlier versions of cassandra.
