What is it?

Highcharts Node.js Export Server converts Highcharts.JS charts into static image files without a browser front end. It accepts chart options as JSON or SVG input and outputs PNG, JPEG, SVG or PDF, which suits generating charts for reports, caching, or slides.

The project can run as a command-line tool, as an HTTP server that accepts POST requests, or as a Node.js module that can be called from your own code. Settings can come from a config file, environment variables, or CLI flags, with later sources taking precedence. The server also supports Docker, rate limiting, SSL, a worker pool with queue limits, and a health endpoint.

You can self-host it to avoid relying on the public export.highcharts.com service, which has rate limits. Using the public server or the export feature requires a valid Highcharts license.

Quick start

  1. 1

Things to know

  • The metadata gives no clear license (NOASSERTION), so check the repository's license terms before use.
  • Exports require a valid Highcharts License, and the public export server has a fair usage policy.
  • By default Highcharts scripts are fetched from the CDN on first export, so the server needs outbound network access unless you use the bundled npm package.
