Come explore how First National Bank of Omaha modernized their front-end development practices by adopting a design-focused approach that leverages UI designs, React component libraries, utility-first CSS with Tailwind, and Storybook. They also implemented mock-service-worker, which enables developers to simulate API responses in a controlled environment, reducing the dependency on real API endpoints during the development process. This approach has improved the overall speed and efficiency of their development process, while ensuring a consistent and visually appealing user experience. The success of this effort resulted in the creation of a Frontend Community of Excellence that is focused on being the authority for frontend best practices and on continuously improving frontend development at the bank.
