A powerful Angular library for building interactive node-based UIs and flow diagrams with declarative components.
ngx-vflow is an open-source Angular library for building interactive node-based user interfaces, such as flow diagrams, node editors, and visual programming tools. It solves the problem of creating complex, customizable graph-based applications within Angular by providing a declarative API, rich interactions, and performance optimizations. The library enables developers to design and manage node connections, subflows, and layouts with ease.
Angular developers building applications that require node-based UIs, such as workflow designers, data pipeline visualizers, diagram editors, or visual programming environments.
Developers choose ngx-vflow for its deep integration with Angular, offering a declarative component-based API, built-in performance features like virtualization, and reactivity through Signals. It stands out by providing full customization, subflow support, and a rich set of interactive tools specifically tailored for Angular projects.
An open source library to build node-based UI with Angular 16+
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Allows full customization of nodes, edges, and handles using Angular components, as highlighted in the README's key features, enabling precise control over UI elements.
Includes virtualization and lazy loading for efficient handling of large graphs, per the README, ensuring smooth interactions even with complex visualizations.
Utilizes Angular Signals to keep internal and external states synchronized, providing a responsive and modern approach to state management, as noted in the features.
Supports dragging, selecting, zooming, panning, and keyboard shortcuts, along with built-in tools like a minimap and snap-to-grid, offering a seamless user experience.
Enables creation of nested flows with parent-child relationships for hierarchical structures, a key feature mentioned in the README for building complex graph-based applications.
Limited to Angular projects, making it unsuitable for teams using other frameworks like React or Vue, which restricts its adoption in mixed-technology environments.
Requires familiarity with Angular and node-based UI concepts, which can be challenging for developers new to graph libraries or Angular's advanced features, despite the documentation.
Has specific version requirements tied to Angular releases, as shown in the compatibility table, which may necessitate frequent updates or cause migration headaches with Angular upgrades.
While highly customizable, it demands significant CSS and component work for styling and integration, unlike libraries with pre-built, polished designs out-of-the-box.
