Understanding Shopify Custom Apps

What are Shopify Custom Apps?

In the Shopify ecosystem, custom apps are developed to extend the platform’s base functionality. Unlike public apps, which are designed for use by multiple stores, custom apps are custom to meet the specific needs of a single store.

Think of custom apps as bespoke solutions. For example, if you need a unique subscription payment system and no existing app fits the bill, a custom app can be created to meet that specific requirement.

How Do Shopify Custom Apps Work?

API Interaction

Custom apps interact with a store’s data using Application Programming Interface (API) endpoints provided by Shopify. APIs allow different software programs to communicate with each other, making it possible to access and manipulate store data.

Shopify offers several APIs, each serving different purposes:

• Storefront API: Retrieves store data for use in themes.
• Admin API: Manages store data and provides two protocols—GraphQL and REST.

GraphQL allows for precise data queries, fetching only the needed information, while REST uses predefined response packets. Due to its precision, GraphQL is often preferred.

Access Permissions

Managing access permissions is crucial for maintaining security and data integrity. For instance, an app that exports orders will need read access to Orders, Customers, and Products data but won’t need write access. Conversely, an app that adds customer tags will require both read and write access to customer data.

Rate Limits

Shopify imposes rate limits on API requests to ensure consistent performance and prevent server overload. This is known as the Leaky Bucket Algorithm. Rate limits help reduce hosting costs, prevent spam, and encourage efficient software design.

By understanding these foundational elements, you can see how custom apps can be designed to meet specific business needs while maintaining security and performance standards.

Next, we’ll explore how to set up your development environment for creating a Shopify custom app.

Setting Up Your Development Environment

To start building a Shopify custom app, you need the right tools and setup. Here’s how to get your development environment ready.

Requirements

Before diving in, ensure you have:

• A Shopify Partner account.
• A development store created under your Partner account.
• The latest version of Shopify CLI installed.
• The latest version of Chrome or Firefox.

Scaffolding a New App

Shopify CLI simplifies creating and managing Shopify apps. Follow these steps to scaffold your new app:

1. Steer to your desired directory: Open your terminal and go to the directory where you want to create your app.

   
   

2. Run the command:

   
   

   shopify app create
   

   
   

   You’ll be prompted to enter a name for your app.

   
   

3. Select the Remix template: Choose Start with Remix. This initializes a new app with the Remix framework and installs all necessary dependencies.

   
   

Once the process completes, you’ll have a new directory with starter code and all dependencies set up.

Starting a Local Development Server

After scaffolding your app, the next step is to start a local development server. This allows you to develop and test your app locally.

1. Steer to your app directory:

   
   

   cd your-app-name
   

   
   

2. Start the local server:

   shopify app dev
   

   Shopify CLI will guide you through logging into your Partner account and selecting your Partner organization. It will also:

   • Create an app in your Partner Dashboard.
   • Connect your local code to the app.
   • Set up a Prisma SQLite database.
   • Create a Cloudflare tunnel to access your app via an HTTPS URL.

This setup ensures your app is accessible via a secure URL, which is essential for development and testing.

Now that you have your development environment ready, you can start working on your custom app. Next, we’ll cover how to install your app on a development store and generate test products.

Building and Testing Your Shopify Custom App

Installing Your App on a Development Store

Once your development environment is set up, the next step is to install your custom app on a development store. This will allow you to test your app in a real-world scenario before making it live.

1. Run the local server: Ensure your local server is running by navigating to your app directory and using the command:

   
   

   shopify app dev
   

   
   

2. Open the preview URL: With the server running, press p to open your app’s preview URL in a browser. This URL will prompt you to install the app on your development store.

   
   

3. Install the app: Click on Install app to add your custom app to the development store. This step links your app with the store, allowing you to start testing its functionality.

   
   

Generating and Testing Products

With your app installed on the development store, you can now generate products and perform thorough testing to ensure everything works as expected.

1. Generate a product: From the home page of your newly installed app, click Generate a product. This action will create a sample product in your development store that you can use for testing purposes.

   
   

2. Test app functionality: Interact with the generated product to test your app’s core features. This includes checking product creation, updates, and deletions to ensure they function correctly.

   
   

3. Automated and manual testing: Conduct both automated and manual tests to uncover any potential issues. Automated tests can cover a wide range of scenarios quickly, while manual tests can help identify usability problems that automated tests might miss.

   
   

4. Consider different configurations: Since public apps need to work across various Shopify stores with different themes and installed apps, test your app under different configurations to ensure compatibility.

   
   

Additional effort for public apps: Public apps require more rigorous testing due to the diversity of Shopify store configurations and the need to handle high peak loads. This means investing in more extensive test scenarios and ensuring robust infrastructure to support a larger user base.

By following these steps, you can ensure that your Shopify custom app is well-tested and ready for deployment. Next, we’ll cover how to deploy and maintain your custom app to keep it running smoothly.

Deploying and Maintaining Your Shopify Custom App

Hosting Considerations

Once your Shopify custom app is ready for deployment, you need to decide how and where it will be hosted. This involves considering several factors such as server installation, compute power, and hosting costs.

Server Installation: Your app needs to be installed on a server that can handle its data and processes. The type of server you choose will depend on the complexity of your app. For a simple app, a basic server might suffice. But for more complex apps, you may need a more powerful server.

Compute Power: The compute power required depends on the tasks your app performs and the volume of data it handles. For example, an app that processes large amounts of data or performs complex calculations will need more compute power than a simple app that performs basic tasks.

Hosting Costs: Hosting costs can vary widely. For a basic app, you might spend between $50-$100 USD per month. However, for an app that handles large amounts of data or performs complex tasks frequently, the costs will be higher. Always factor in these costs when planning your app development budget.

App Maintenance

Maintaining your Shopify custom app is crucial for its smooth operation and longevity. This involves regular updates, error monitoring, and managing ongoing maintenance costs.

Error Monitoring: Implement systems to monitor your app for real-time errors. This can help you quickly identify and fix issues before they affect your users. While setting up error monitoring can be time-consuming and costly, it’s an investment that pays off in the long run by minimizing downtime.

Ongoing Maintenance Costs: Maintenance costs can come as a surprise. Even with the best planning, unexpected issues can arise. Budget for ongoing maintenance to cover these unforeseen problems.

API Versioning: Shopify frequently updates its APIs, which can lead to changes that may break your app if not addressed. Keep track of which API versions your app uses and update them as needed to ensure compatibility. Shopify’s rigid release schedule makes it easier to predict when updates will occur, allowing you to plan accordingly.

Hosting and maintaining your Shopify custom app requires careful planning and ongoing effort. By considering these factors, you can ensure that your app runs smoothly and provides value to its users. Next, we’ll explore some successful examples of Shopify custom apps to give you inspiration for your own project.
