JavaScript Export Service

This repository contains an Express server and a lambda service (Serverless) to export JavaScript visualisations with Playwright.

The purpose of this project is to provide a method of rendering JavaScript visualisations server-side as a fallback for when JavaScript isn't avalible on the client.

This service comes preconfigured for NHSD DataViz and Highcharts, but can be extended by modifying libraris.js.
