{
dendrosId: string;
ownerId: string;
config: {
title: string;
slug: string;
description?: string;
isPublished?: boolean;
allowAnonymous?: boolean;
};
graph: {
nodes: Node[]; // Questions, Info, Logic, Endings
edges: Edge[]; // Connections with conditions
};
createdAt?: Date;
updatedAt?: Date;
}- Root: Starting point of the flow
- Question: Multiple choice, checkbox, and text input questions
- Info: Information displays
- End: Terminal nodes
- Creator Access: Firebase Authentication required
- Ownership Validation: Server-side checks ensure only owners can edit
- Public Access: Anyone can access published Dendros via link
- Unpublish Feature: Pause submissions while preserving data
