Horizontal Flow

A diagram can go from left to right or from top to bottom, but you can also create mixed ones. For controlling the direction of a diagram you can adjust the handle positions of a node with the sourcePosition and targetPosition props.

<script lang="ts">
  import { writable } from 'svelte/store';
  import {
    SvelteFlow,
    Controls,
    Background,
    BackgroundVariant,
    MiniMap,
    type NodeTypes,
    type Node,
    type Edge
  } from '@xyflow/svelte';
 
  import { initialNodes, initialEdges } from './nodes-and-edges';
 
  import '@xyflow/svelte/dist/style.css';
 
  const nodes = writable<Node[]>(initialNodes);
 
  const edges = writable<Edge[]>(initialEdges);
</script>
 
<main>
  <SvelteFlow {nodes} {edges} fitView minZoom={0.1} maxZoom={2.5}>
    <Controls />
    <Background variant={BackgroundVariant.Dots} />
    <MiniMap />
  </SvelteFlow>
</main>
 
<style>
  main {
    height: 100vh;
  }
 
  :global(.svelte-flow .svelte-flow__node.parent) {
    background-color: rgba(220, 220, 255, 0.4);
  }
</style>
