Worked on stabilizing the Travelopia/web-components codebase by focusing on runtime reliability and maintainability of the TPSlider component. Addressed a runtime type error by making the update method asynchronous, ensuring it awaited the definition of all dependent custom elements before accessing their properties or methods. This approach reduced the risk of undefined component access and improved the overall developer experience. Additionally, improved code readability and consistency by correcting a typographical error in a key variable name. Utilized TypeScript and front end development skills with a focus on web components, laying groundwork for future enhancements and simplifying ongoing maintenance efforts.
