Question 1

How do I create custom nodes in Drawflow?

Accepted Answer

You can define nodes using HTML strings or Vue components via the registerNode method. For HTML, pass a string with df-* attributes for data binding; for Vue, register the component with props and use it in nodes, as shown in the 'Node example' and 'Register Node' sections.

Question 2

Drawflow vs React Flow: which should I choose?

Accepted Answer

Drawflow is better for Vue projects or when you need a lightweight, dependency-free library with quick setup. React Flow is more feature-rich for React ecosystems with built-in tools for complex diagrams and better performance scaling. Consider your framework and required features.

Question 3

Can I use Drawflow with React?

Accepted Answer

Yes, but it requires manual integration since Drawflow has no native React support. You'll need to wrap the library in a React component and handle events and state management yourself, which can be more complex than using a React-specific solution like React Flow.

Question 4

How to export flow data to a backend in Drawflow?

Accepted Answer

Drawflow exports flow data as JSON using the export() method. You can send this JSON to your server via AJAX or fetch for persistence, and import it back using import() to restore the flow state, as detailed in the 'Export / Import' section.

Question 5

Is Drawflow good for large diagrams with many nodes?

Accepted Answer

Drawflow can handle moderate-sized flows, but for thousands of nodes, performance might degrade due to DOM rendering. Optimization techniques like virtual scrolling are not built-in, so you may need to implement custom solutions or limit node count.

Question 6

How to style connections and nodes in Drawflow?

Accepted Answer

Style nodes and connections by overriding CSS classes. The library provides a base stylesheet, but for custom looks, use the theme generator or write your own CSS to target elements like .drawflow-node and .drawflow-connection, as mentioned in the 'THEME EDIT GENERATOR' link.
