__Vue Flow: A highly customizable Vue 3 Flowchart component.__

With Vue Flow, you can build your own, customized node-based applications like static diagrams or even more complex and
interactive editors!

You can find a detailed explanation of how to get started in the [documentation](https://vueflow.dev/guide/) or check
the [examples](https://vueflow.dev/examples/).

## 🛠 Setup

```bash
$ 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:

```vue
<!-- 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:__

```css
/* 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.

## 🧪 Development

### Prerequisites

- [Node.js v14+](https://nodejs.org/)
- [PnPm](https://pnpm.io/)


```bash
# skip if you already have pnpm installed
$ npm i -g pnpm

# start examples
$ pnpm dev

# build all packages
$ pnpm build
```

### 🐳 Dev Container

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.
