HealthHero

To reach a wide target audience

As with any other business, HealthHero strives to reach a broad target audience. Therefore, it was decided to develop a PWA and ensure its smooth interoperability across a wide range of devices under any of the use scenarios. Also, particular attention was paid to the semantic layout and special tags enabling interaction with voice readers for visually impaired users.

To optimize the maintenance of client sites

One of the peculiarities of HealthHero is that it provides its appointment scheduling platform to multiple healthcare facilities. Some of them prefer to use its standard design, others would like to apply their branded UI. In the latter case, developers have to customize website design whilst keeping the core business logic as it is.

As a result, all core logic, services, and components reused in every client site were moved to a separate monorepo package. Thanks to this, whenever there is a need to implement changes relevant to all clients, developers make corresponding changes to the core package only.

To easily customize logic across web apps

While all web apps use the core logic, some of them don’t need to have certain functionality. To easily handle this, implementation of a feature-flag approach simplifies and optimizes development and deployment. Implementing hooks and wrappers that regulate the representation or behavior of certain functionality means that a developer simply changes a flag in a configuration file for the desired functionality.

To create a design system

When our developers joined the team, they didn’t have a ready-to-use design system in place. Its creation was in progress, and some components had already been created but used chaotically. With the help of our developers, the team completed the work on the design system and successfully implemented it. After that, it was also decided to replace SCSS with Tailwind as it was considered to be a more convenient and appropriate framework to deal with styles on the projects.

To implement E2E testing

There was a key requirement to implement E2E testing on the project using Cypress. Particular attention was paid to coverage of real-world test scenarios as many variants of user behavior existed. Our developer was responsible for maintaining user cases and adding new ones.
