What is Shopify?
Nowadays e-commerce is using more and if you want to set up your online store then as a quick setup and solution Shopify will come in mind. It allows to sell merchants to their own products even it is physical or digital products. With Shopify merchants can build there own brands to be sold on their name rather than online shopping platforms like Amazon, eBay, Flipkart, and more. Shopify is reducing the time of store setup as well as it brings less interaction with a technical person so cost saving will be also managing with fast store setup.
What is Shopify Apps?
As you all know Shopify is built with Ruby on Rails. so it is better to create Shopify apps with ruby on rails. Shopify Apps will be used in any Shopify store as a plugin where merchants want to enhance their store in terms of functionality. They don’t need an extra technical team to build the functionality of what they needed and save time. They can use existing Shopify Apps from the Shopify App store and if they want any private apps then also merchant will create with help of Shopify App Development team.
How to create Shopify Apps with Ruby On Rails?
To create the Shopify app, you need to follow these steps
- Create a Shopify Partner account
- Once you create that, you will need to create a custom Shopify app within the partner dashboard
- Setup URLs within the app. Here local machine URL like localhost will not work so you need ngrok or another tunneling software like ssh, localtunnel, and more.
- App URL: “https://{your domain}”
- Redirection URL: “https://{your_domain}/auth/shopify/callback”
- Get the API key and API secret key from the app.
SSL certificate is required if you are using your own domain after deployment on the server. (Make sure you use https://)
Now let’s create Ruby On Rails application and integrate Shopify app gem within it for create Shopify apps
Create a new rails application with
$ rails new my_shopify_app
Then open the Gemfile and add Shopify app gem into it
$ gem 'shopify_app'
Then install the gem with a
$ bundle install
This gem includes default generators like install, shop, and home controller.
This is the recommended way to start a new app from scratch:
$ rails generate shopify_app
After generating generators, add new tables in the database with the command
$ rake db:migrate
After that setup API key and API Secret into the rails app. Set both keys as an environment variable and add this in shopify_app.rb file:
ShopifyApp.configure do |config|
config.application_name = "Example app"
config.api_key = ENV['SHOPIFY_APP_API_KEY']
config.secret = ENV['SHOPIFY_APP_SECRET']
config.scope = "read_products, read_orders, read_customers, write_customers, read_orders"
config.embedded_app = true
config.after_authenticate_job = false
end
here,
- if you don’t want your app embedded with Shopify then make
config.embedded_app = false- scope means whatever permission you need from Shopify to get access data into Shopify apps. Make sure you can ask only that permission which you needed.
You can install this app on your store with URL which you have created with tunnel link(ngrok or other which you have used) after starting rails server with rails s
It will ask for shop_domain where you want to install this app like this. So enter your shop domain and install the app.
Now you can enjoy your Shopify app and play with that with different products, customers, orders, theme customization, etc.
During the installation of the app into your store, you can create some default webhooks as well which you needed in your app using Shopify API.
You just need to add this snippet into shopify_app.rb file
ShopifyApp.configure do |config|
Config.application_name = “Example app”
…
topics = %w[app/uninstalled orders/create orders/delete]
config.webhooks = topics.each_with_object([]) do |topic, a|
options = {
topic: topic,
format: "json",
address: "https://#{your_domain}/webhooks/#{topic.parameterize(separator: '_')}"
}
end
If you don’t want to create a default webhook while app installs, then you can use this code to create webhooks within code anywhere.
topics = %w[app/uninstalled orders/create orders/delete]
shop.with_shopify_session do
topics.each do |topic|
ShopifyAPI::Webhook.create({
topic: topic,
format: "json",
address: "https://#{your_domain}/webhooks/#{topic.parameterize(separator: '_')}"
})
end
end

While that is true, the benefits of hiring Ruby on Rails developer are way too many for a project to pass on the opportunity.
This phenomenon is also called parallel development.
Leads to Speedy Development, Thanks to a Rich Library
Ruby on Rails is a language that puts more importance upon the software design paradigm convention, rather than the configuration.
The direct implication of this fact is that the design of the framework heavily reduces the number of decisions a developer would normally have to make.
Modules represent yet another tool that helps this language better organize the methods, constants, and classes, into units or groups.

Ruby on Rails is a boon for programmers as it requires less coding.
It facilitates swift and quick development of websites and apps.
Being a cross-platform solution, it is ideal for start-ups and small businesses.
It helps to save 20-50% of the time required for building websites when compared to other languages.
RoR components can be reused and so, one can expect the solutions faster.
Are you worried about the costs of development as the other developer would have to start from scratch?
