Technology Stack
This document outlines the technology choices and constraints for the AG Grid codebase.
Core Principles
Zero Runtime Dependencies
The main AG Grid libraries (ag-grid-community, ag-grid-enterprise) must have ZERO third-party runtime dependencies. This ensures:
- Minimal bundle size for end users
- No dependency conflicts
- Complete control over behaviour
- Predictable performance characteristics
Framework Agnostic Core
The core grid logic is framework-agnostic. Framework-specific wrappers (ag-grid-react, ag-grid-angular, ag-grid-vue3) provide integrations while the core remains pure TypeScript.
Build System
- Nx: Monorepo orchestration and build caching
- Yarn: Package management (v1.x)
- TypeScript: Strict mode enabled across all packages
- ESBuild/Rollup: Bundle generation
Runtime Technologies
Rendering
- Virtual DOM: Custom high-performance rendering engine
- CSS-in-JS: Avoided - use CSS modules and traditional stylesheets
- Canvas: Used only for specific features (e.g., sparklines)
State Management
- Custom internal state management - no external libraries
Testing Technologies
- Jest: Unit and integration testing
- Playwright: E2E testing
- jsdom: DOM simulation for unit tests
Code Style
- ESLint: Linting with custom rules
- Prettier: Code formatting (via
yarn nx format --sort-root-tsconfig-paths=false)
- TypeScript Strict Mode: Enforced across all packages
Browser Support
- Modern browsers only (ES2020 target)
- No IE11 support
- See browserslist configuration for specifics
Documentation
- Astro: Static site generation for documentation
- MDX/Markdoc: Documentation content format
