If you are the BigCommerce merchants who show lots of interest about building your own application, this article will give you a closer look at BigCommerce App Development, from beginning to advanced knowledge.

What is BigCommerce app development?

“BigCommerce app development” refers to creating custom applications or integrating existing software tools to extend and enhance the functionality of BigCommerce stores. 

The development phase is aimed at improving various aspects of an e-commerce operation, including but not limited to marketing efforts, analytics, inventory management, and the overall customer experience.

Requirements before beginning BigCommerce app development

Before diving into creating your BigCommerce app, there are a few things you need to have in place:

  1. BigCommerce Sandbox Store: This is essential for testing your app installation. Think of it like a playground where you can try out your app without positively affecting actual BigCommerce store owners. It’s like practicing before the big game.
  2. Developer Portal Account: You must sign up for a BigCommerce developer account in the Developer Portal. This account allows you to register your submit apps. It’s like having a ticket to the developer’s backstage area.
  3. BigCommerce Partnership: To publish your app to the BigCommerce marketplace, you need to be one of the BigCommerce partners. It’s like being on the guest list to showcase your app to the world.

How to start building BigCommerce Apps

1. Test former apps

Install with npm:

First things first, ensure you have Node.js installed on your computer. Confirm node is installed and check its version by running this terminal command: node -v 

Node.js installed
Node.js installed

Now, let’s install ngrok globally using npm. This command will make ngrok accessible from any directory: npm install -g ngrok 

Install ngrok
Install ngrok

Starting ngrok:

Open up a terminal window and navigate to the location where you unzipped ngrok. You’re good to go from any directory if you installed it globally or added it to your $PATH.

Now, let’s fire it up! Run the following command to start ngrok and create a tunnel to localhost port 3000: ngrok http 3000 

start ngrok
start ngrok

To stop ngrok, simply press Ctrl + C in the terminal window where it’s running.

Creating an Express App:

Install the Express Generator: This command line tool helps generate an Express app skeleton effortlessly. Install it globally using npm: npm install express-generator -g

Install the Express Generator

Generate the App: Specify the view engine (we’ll use handlebars) and create a folder named “myapp”: express –view=hbs myapp

Generate the App
Generate the App

Navigate to App Directory: Move into the “myapp” folder: cd myapp

Install Dependencies: Install all the necessary dependencies for your app: npm install

Tunneling ngrok to localhost:

Start ngrok: Now, let’s tunnel your local server with ngrok. Open a terminal window, navigate to your “myapp” directory, and run your app: npm start 

Access the app Locally: Open a browser window and go to LocalHost3000. You should see your Express app’s homepage.

Tunnel with ngrok: Open another terminal window (keep the first one running) and start ngrok on port 3000: ngrok http 3000

Access the Tunnel URL: Copy the HTTPS forwarding URL from the terminal and paste it into a new browser tab. You should see the same Express app homepage as before.

2. Registering a draft app

Sign up for a BigCommerce Store: 

You’ll need a store before anything else. Sign up for a free trial at their company website here

Create a Dev Tools Account: 

Head to the developer area and click “Create Account” in the top right corner. Use the same email address you used for your trial store. This ensures that your trial store and Dev Tools accounts are linked, making any apps you create in Dev Tools available for installation in your store’s control panel.

Login and Create an App:

  • Log in to Dev center –> Dev Tools and hit the orange “Create an app” button.

  • Give your app a name. It can be anything you like, such as “My Test App” or “Node App“.

  • Click “Create App“.
  • Once created, click the “Edit App” icon on your newly created app.

Setup App Details:

Step 1: You can skip filling out the profile form if you’re not planning to submit your app to the App Marketplace. However, uploading an image to the App summary area is nice for a better visual representation.

Step 2: Skip this step; it’s only required for BigCommerce developers submitting apps to the Marketplace.

Step 3: Here, fill in the Callback URL fields. Replace “example.com” with the HTTPS forwarding URL from ngrok. 

For example:

  • Auth: https://4022ffe4111.ngrok.io/auth
  • Load: https://4022ffe4111.ngrok.io/load
  • Uninstall: https://4022ffe4111.ngrok.io/uninstall

Step 4: Click “Next” until you reach Step 6, then hit “Update and Close“.

Step 4: If the app handles all the requests successfully, it will be installed, and you can start developing its key features immediately.
