Chart.js Node.js Canvas Renderer

chartjs-node-canvas is a Node.js library that enables server-side rendering of Chart.js charts into static image files (PNG, JPEG). It achieves this by utilizing the `canvas` package, which provides a Canvas API implementation compatible with Node.js environments, bypassing browser-specific rendering requirements. The current stable version is 5.0.0, which maintains compatibility with Chart.js v3.x and v4.x. While there isn't a strict, rapid release cadence, the project is actively maintained, with regular updates for dependency bumps and Node.js version support. Its primary differentiator is providing a reliable, performant way to generate Chart.js images outside of a browser, essential for tasks like generating reports, social media share images, or email attachments from server-side applications. It integrates directly with Chart.js as a peer dependency, requiring Chart.js itself to be installed separately, and allowing developers to manage its version.
