Shopify Upsell App Enhancement Using Node.js and React

The Shopify upsell application needed improvements while maintaining its existing architecture which used Node.js and React and PostgreSQL database management system. The platform enables users to offer any catalog product for upselling purposes but we needed to solve present bugs and migrate servers and support Shopify 2.0 requirements and incorporate new features based on user requests.

Challenge

Our main challenges were threefold: transition the hosting, ensure compatibility with Shopify 2.0 standards, and enrich the app with additional functionalities. The application hosting required transfer from the Digital Ocean server which the project partner managed to a Digital Ocean server which belonged to the project initiator. The application maintained its organized structure but it operated with outdated libraries that needed to be updated to keep functioning.

Process

The first step involved transferring the app to a fresh Digital Ocean setup which protected all system data and operational elements. The following step involved updating the app's compatibility through the replacement of EASDK calls with Shopify's App Bridge to fulfill Shopify's modern guidelines. After resolving bugs the team fixed discount errors in cart operations and corrected product variant presentation that matched user selections.

To enhance user experience:

• Limited upsell selections were introduced, offering control over free giveaway choices. The Recharge App joined the system to enhance the functionality of the application. The addition of analytics tools provided users with better analytical capabilities.

Outcome

The project completed its main objectives through delivering substantial improvements to its core aspects. The app achieves Shopify 2.0 compliance and provides an enhanced user interface backed by analytical features.

The server service relocation happened without interruptions so operations continued without interruptions. The application gained operational flow improvements and discount accuracy through essential bug fixes. The app gained more usage possibilities through the addition of new restrictions together with integration features.

Impact

The enhanced structure and capabilities of the app enable Shopify users to experience better upselling functions. The platform standard compliance updates together with added valuable analytics and functional enhancements provided merchants with powerful tools.
