Print Map Reports in Risk Evaluation Website

I was hired by UK location intelligence geocoding provider Addresscloud to enhance their platform's print report functionality. The company's web app consists of a map-based panel with a list of selected property information on exposure to different types of risk and related metrics.

I developed a javascript utility that generates a printable A4 PDF report of the current map view and related fetched statistics into the layout requested by the client. The code resizes the map canvas into the calculated print resolution size, and builds the PDF layout using jsPDF client-side, importing data like user email from application state.

The original code was optimised with 200kb reduction in bundle size and the user experience was enhanced, including a buffering modal while the generation works, and a responsive two column consistent visual design in the final print.
