Notes about our technologies

All of our public Shopify apps use React and Polaris for the front end framework, and either Rails or Node for the back end.

The Shopify Analyzer is full JavaScript, built on the Angular framework.

Shopify App Development

These are the key skills for building Shopify apps:

  • Shopify API
  • Shopify Polaris
  • React
  • Server side language / framework
  • Hosting

If you don’t need to build an embedded UI for your app, you can skip React and Polaris.

Shopify App Development – Shopify’s app dev resource center.

Shopify API

User Interface

Polaris Components – modular components to provide a Shopify-like experience in your app.

React – JS library for building user interfaces. Works great with Polaris.


Heroku – Easiest way to serve and deploy apps.

Digital Ocean – Another good place to host apps, some DevOps knowledge required.

Server side language

You can build mini apps / scripts using a language like Ruby, Python, or PHP.

For full apps, Rails and Node are the most supported frameworks (for plugins, documentation, examples).

Shopify is built on Rails and they maintain the very useful shopify_app gem, making Rails a good choice for Shopify app development.

Shopify Theme Development

Working with Shopify themes requires these skills:

  • HTML
  • CSS
  • JavaScript
  • Liquid

Liquid is the templating language Shopify themes are built on.

If you want to become a Shopify developer, focus on mastering HTML and CSS first, then JavaScript.

Reading the liquid docs front to back isn’t necessary, it’s easy to pickup so just learn the basics then use the docs as reference when you need it.

If you want to build your own themes, learn more in the Shopify Theme Development resources.

Final Notes

The best way to learn is by building. Take a course and build their demo project, then build something of your own to solidify your knowledge.
