AI BriefingA Front-end Developer's Retrospective on the Planned Exhibition Revamp
Key point
Oliveyoung shares the rendering issues and solutions faced while converting its existing JSP-based planned exhibition system to Next.js.
Details
Oliveyoung's Store Display Squad carried out a project to convert the existing planned exhibition system, implemented in JSP, to Next.js in Q2–Q3 2024. The core challenge was how to insert the existing React components inside custom HTML modules generated by the back-office (BO) editor.
To solve this, they adopted an approach where the HTML is first injected into the DOM via dangerouslySetInnerHTML, and then the createRoot API is used to re-render React components into specific elements. The context loss issue for global state management libraries like Recoil and React-query that occurred during this process was resolved by wrapping each createRoot call with a Wrapper component.
Regarding concerns about performance degradation from creating multiple Virtual DOMs, they verified this using React.Profiler. Test results confirmed that changes to components created with createRoot did not affect the rendering of existing components, proving there were no performance issues.
