🛠 Setup

$ npm i @vue-flow/core

# or
$ yarn add @vue-flow/core

🎮 Quickstart

A flow consists of nodes and edges (or just nodes). Together they are called elements.

Each element needs a unique id.

A node also needs an XY position. An edge needs a source (node id) and a target (node id).

A basic setup looks like this:

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

const elements = ref([
  {
    id: '1',
    label: 'node 1',
    position: { x: 100, y: 100 },
  },
  {
    id: '2',
    label: 'node 2',
    position: { x: 100, y: 200 },
  },
  {
    id: 'e1-2',
    target: '2',
    source: '1',
  },
])
</script>

<template>
  <VueFlow v-model="elements"></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";

🪴 Vue 2

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.
