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

Vue Flow is a bridge to the world of interactive flowcharts and graphs, empowering you to bring
interactivity to your graphic representations. Whether it's crafting personal diagrams, generating dynamic
editors, or anything else your imagination conjures up, Vue Flow has you covered.

You can find a detailed explanation on how to get started [here](https://vueflow.dev/guide/) or jump right into
the [examples](https://vueflow.dev/examples/).

## 🛠 Setup

```bash
$ npm i @vue-flow/core

# or
$ pnpm i @vue-flow/core

# or
$ yarn add @vue-flow/core
```

## 🎮 Quickstart

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.

```vue
<!-- Flowchart.vue -->
<script setup>
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:__

```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";
```

Do __not__ scope these styles with `scoped` in your component.

### 🪴 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 v18+](https://nodejs.org/)
- [pnpm](https://pnpm.io/)

```bash
# install pnpm if you haven't already
$ 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.
