A reverse proxy tool that sets correction instruction pins on the screen with zero code embedding.
To free web production from "correction instructions" that involve back-and-forth emails and screenshots with red markings, we developed our own screen review tool, PinRemark, using Node.js and three dependency packages. This includes URL rewriting for a reverse proxy that injects widgets without adding any code to the target site, Shadow DOM isolation, double saving of pin positions, and the implementation of WebSocket synchronization, along with explanations of potential pitfalls. For more details, please refer to the technical column in the related links.
