This is the source code for `@swimlane/ngx-datatable`, an Angular component library for building high-performance, feature-rich data tables. It provides virtual scrolling, client- and server-side sorting/paging, column reordering/resizing, row selection (single, multi, checkbox), tree view, row grouping, summary rows, and extensive custom template support. The library is built with Angular's signals-based reactivity and OnPush change detection, offering a modern reactive API. The repository also includes a comprehensive demo application and a test suite using Vitest, Angular CDK ComponentHarness, and Playwright for E2E. While the codebase demonstrates strong architectural patterns and reusable utilities, it suffers from a high number of open issues (917), some deprecated API surfaces, and a test stack in migration flux, indicating a mature but somewhat stale maintenance state.

ngx-graph is an Angular library for rendering directed acyclic graphs (DAG) and other graph structures using SVG. It provides a standalone GraphComponent with signal-based inputs and outputs, supporting multiple built-in layout engines (Dagre, DagreCluster, DagreNodesOnly, D3 force-directed, Cola force-directed) and custom layouts via a Layout interface. The component handles viewport transformations (pan, zoom), node dragging, minimap, and rich layout morph animations between graph updates. The architecture centers on a flexible layout service pattern where each layout is a class implementing run/updateEdge/hooks, and the GraphComponent orchestrates layout calculations, SVG rendering, and interaction. The codebase demonstrates modern Angular practices (signals, standalone components, OnPush change detection) and includes comprehensive test coverage. It is maintained by Swimlane with regular releases and extensive documentation via Storybook.
