The HPCC Visualization Framework is a comprehensive TypeScript/JavaScript-based data visualization library that provides charting, graphing, and dashboard capabilities. Published as scoped NPM packages under @hpcc-js, this framework is designed to work seamlessly with the HPCC Systems big data platform while being flexible enough for general-purpose visualization needs.
- Quick Start: Covers the basics on how to include the framework into your web application.
- Tutorials: Starting with a simple "hello world", the tutorials walk through the basics of instantiating visualizations, fetching data and creating dashboards.
- Gallery: Interactive gallery with live code examples and a property editor for discovering the capabilities of each visualization.
This is a Lerna-based monorepo with packages organized in the /packages/ directory. Each package has its own package.json, build configuration, and TypeScript setup. Packages are published independently to NPM under the @hpcc-js/ scope.
- Vite is the primary compiler and bundler for all packages
- TypeScript source code with strict configuration
- Multiple module formats: ESM, UMD, and IIFE
- Source maps generated for all builds
- PostCSS for CSS processing and minification

- Direct CDN usage via unpkg
To install via npm, use npm install with the specific packages you need. Each package is scoped with "@hpcc-js":
npm install @hpcc-js/chart @hpcc-js/map @hpcc-js/commonFor quick prototyping, you can load packages directly from unpkg CDN:
<script src="https://unpkg.com/@hpcc-js/util"></script>
<script src="https://unpkg.com/@hpcc-js/api"></script>
<script src="https://unpkg.com/@hpcc-js/common"></script>
<script src="https://unpkg.com/@hpcc-js/chart"></script>You can see all available packages at: https://www.npmjs.com/search?q=maintainer:hpcc-js
