In Vue Flow, an application structure consists of nodes and edges, all of which are categorised as elements.

Each element requires a unique id.

Nodes additionally need an XY-position, while edges require a source and a target, both represented by node ids.

<!-- Flowchart.vue -->
<script setup>
import { ref } from 'vue'  
import { VueFlow } from '@vue-flow/core'

const nodes = ref([
  { id: '1', type: 'input', label: 'Node 1', position: { x: 250, y: 5 } },
  { id: '2', label: 'Node 2', position: { x: 100, y: 100 } },
  { id: '3', label: 'Node 3', position: { x: 400, y: 100 } },
  { id: '4', label: 'Node 4', position: { x: 400, y: 200 } },
])
  
const edges = ref([
  { id: 'e1-2', source: '1', target: '2', animated: true },
  { id: 'e1-3', source: '1', target: '3' },
])
</script>

<template>
  <VueFlow v-model:nodes="nodes" v-model:edges="edges"></VueFlow>
</template>

⚠️ Make sure to import the necessary styles:

/* import the required styles */
@import "@vue-flow/core/dist/style.css";

/* import the default theme (optional) */
@import "@vue-flow/core/dist/theme-default.css";

Do not scope these styles with scoped in your component.

This library doesn't work with Vue 2.

Vue Flow uses features that are exclusive to Vue 3, therefore there is no support for Vue 2, nor will there be any support in the future, sorry.

• Node.js v20+
• pnpm v9+

# install pnpm if you haven't already
$ npm i -g pnpm

# start examples
$ pnpm dev

# build all packages
$ pnpm build

To start using development containers, install the Docker extension for VSCode. After installing the extension, open the connection menu either on the bottom left or open it via the commands tab. Select the Open Folder in Container option to mount the project.

The development container will spin up all packages example apps and forward the ports to your machine.
