1. Set Up Your Development Environment

Before you start developing your custom Shopify app, you need to set up your development environment. This involves installing necessary tools and software.

  1. Install Node.js: Shopify apps are built using Node.js. You can download it from the official Node.js website.
  2. Install ngrok: ngrok is a tool that allows you to expose a local server to the internet. This is essential for testing your app. You can download it from the ngrok website.
  3. Install a Code Editor: A good code editor like Visual Studio Code or Sublime Text will make your development process smoother.

2. Create a Shopify Partner Account

To create and manage your custom app, you need a Shopify Partner account. Follow these steps:

  1. Go to the Shopify Partners page and sign up for a free account.
  2. Once registered, log in to your account and navigate to the 'Apps' section.
  3. Click on the 'Create App' button to start a new app project.

3. Set Up Your App in Shopify

After creating your app in the Shopify Partner Dashboard, you need to configure it:

  1. Enter your app name and select the development store where you will test your app.
  2. Provide necessary URLs for the app, such as the App URL and Redirect URL. These URLs should point to your local development environment, which can be set up using ngrok.

4. Develop Your App

Now that your environment is set up and your app is created, you can start developing. Here are some key steps:

  1. Initialize Your Project: Use the Shopify CLI to generate your app's boilerplate code.
  2. Authenticate Your App: Implement OAuth to authenticate your app with Shopify.
  3. Build Your App's Features: Use Shopify APIs to add the desired functionalities. For example, you can use the Admin API to manage products and orders.

5. Test Your App

Testing is crucial to ensure your app works correctly. Use the following steps:

  1. Run your app locally and use ngrok to expose it to the internet.
  2. Install your app on your development store and test all functionalities.
  3. Debug any issues that arise during testing.

6. Submit Your App

Once you have thoroughly tested your app and are satisfied with its performance, you can submit it to the Shopify App Store:

  1. Go to your Shopify Partner Dashboard and navigate to your app.
  2. Click on 'Submit for Review' and follow the submission guidelines provided by Shopify.
  3. Wait for Shopify to review and approve your app.

Example Code Snippet

Here is a simple example of how to set up a basic Shopify app:

const express = require('express');
const app = express();
const port = 3000;

app.get(‘/’, (req, res) => {
res.send(‘Hello Shopify!’);

app.listen(port, () => {
console.log(App listening at http://localhost:${port});
