# AG Charts Technology Stack
This document outlines the preferred technologies and architectural constraints for the AG Charts monorepo.
## Critical Requirement: Zero Runtime Dependencies
**The main AG Charts libraries (`ag-charts-core`, `ag-charts-community`, `ag-charts-enterprise`) MUST have ZERO third-party runtime dependencies.** Only internal AG Charts packages and dev dependencies for build/test tooling are allowed.
## Core Libraries
| Package | Runtime Dependencies | Purpose |
| ---------------------- | ------------------------------------------------------- | ---------------------------------------- |
| `ag-charts-types` | **NONE** (zero dependencies) | TypeScript type definitions |
| `ag-charts-core` | `ag-charts-types` only | Core rendering engine and utilities |
| `ag-charts-locale` | **NONE** (zero dependencies) | Internationalization (40+ languages) |
| `ag-charts-community` | `ag-charts-core`, `ag-charts-types`, `ag-charts-locale` | MIT licensed charts library |
| `ag-charts-enterprise` | `ag-charts-community`, `ag-charts-core` | Commercial charts with advanced features |
**Core Technologies:**
- **TypeScript**: Primary language with strict mode enabled
- **Canvas API**: Custom high-performance rendering with scene graph
- **Pure JavaScript**: No external runtime dependencies
## Framework Wrappers
| Package | Runtime Dependencies | Peer Dependencies |
| ------------------- | ------------------------------ | ------------------------------------------------------ |
| `ag-charts-react` | `ag-charts-community` | `react ^18.0.0 \|\| ^19.0.0` |
| `ag-charts-angular` | `ag-charts-community`, `tslib` | `@angular/common >= 20.0.0`, `@angular/core >= 20.0.0` |
| `ag-charts-vue3` | `ag-charts-community` | `vue ^3.5.0` |
## Documentation Website (`ag-charts-website`)
| Technology | Purpose |
| ------------------ | ----------------------------------- |
| **Astro** | Static site generator |
| **Markdoc** | Content authoring for documentation |
| **React** | Interactive components within Astro |
| **Vite** | Development server and build tool |
| **Shiki** | Syntax highlighting |
| **Algolia** | Documentation search |
| **Nanostores** | Lightweight state management |
| **Cheerio** | Server-side HTML parsing |
## Development & Build Tools
| Tool | Purpose | Used By |
| ----------------------- | ---------------------------------- | ------------------ |
| **Nx** | Monorepo orchestration and caching | All packages |
| **TypeScript** | Type checking and compilation | All packages |
| **SWC** | Fast transpilation | Build system |
| **ESBuild** | High-performance bundling | Production builds |
| **Vitest** | Unit and visual snapshot testing | All packages |
| **Playwright** | E2E testing | Website |
| **ESLint** | Code linting with custom rules | All packages |
| **Prettier** | Code formatting | All packages |
| **Size Limit** | Bundle size monitoring | Core libraries |
## Version Requirements
Tool and runtime versions live in the root `package.json` (`engines`, `devDependencies`) and `.nvmrc` — read them there rather than from this page.
- **Build Target**: ES2020 (excludes IE)
- **TypeScript**: Strict mode enabled across all packages
