Vue bare components to create svg interactive graphs, diagrams or node visual tools.
https://txlabs.github.io/vnodes/
npm install vnodes
<template>
<screen ref="screen">
<edge v-for="edge in graph.edges" :data="edge" :nodes="graph.nodes" :key="edge.id">
</edge>
<node v-for="node in graph.nodes" :data="node" :key="node.id">
<!-- html can be placed here, defaults to <div>{{node.id}}</div> -->
</node>
</screen>
</template>
import { Screen, Node, Edge, graph } from 'vnodes'
export default {
components: {
Screen,
Node,
Edge
}
data () {
return {
graph: new graph()
}
}
created () {
this.graph.createNode('a')
this.graph.createNode('b')
this.graph.createEdge('a', 'b')
this.graph.graphNodes()
}
}
Vnodes components are independent and can be used only when desired. Instead of locking into a complex framework, these components are designed to be minimal and still allow to build complex applications.
Svg wrapper with zoom, panning and other features.
<screen>
<circle cx="50" cy="50" r="50" fill="red"/>
</screen>
Html wrapper for svg with additional features like, dragging and fitting contents.
<svg width="500" height="500">
<node :data="{
id: 'test',
x: 100,
y: 100,
width: 250,
height: 150}">
<h1>My First Node!</h1>
</node>
</svg>
Connects nodes using svg lines
<edge :data="{
from: { x: 0, y: 0},
to: { x: 100, y: 100}}"
></edge>
Edges require node references { from: id|Object, to: String|Object }
, if nodes are refered by id(String)
an array nodes
must be passed:
<edge
:data="{from: 'A', to: 'B'}"
:nodes="[{id: 'A' ... ]">
</edge>
Edges can take anchor information to offset their position relative to a node,
<edge :data="{
from: nodes[0],
to: nodes[1],
fromAnchor: 'center',
toAnchor: 'top-left',
}">
anchors format can be:
- String
'center', 'left', 'right', 'top', 'top-left', 'top-right', 'bottom', 'bottom-left', 'bottom-right', 'cirlce', 'rect'
- Object
{ x?:Number|String, y?: Number|String, align?: String, snap?: String }
Examples of valid anchors:
null
{ x: 0, y: 0}
{ x: 10, y: 10 }
{ x: '50%', '50%' }
{ x: '50%', '50%', snap: 'rect' }
{ align: 'bottom-right' }
'center'
'top-left'
'circle' // snaps offset to circle with radius node.width/2
'rect' // snaps offset to node rectangle
Surrounds a group of nodes with a rectangle, allows dragging multiple nodes.
<group :nodes="nodes">
<h1>Group Label</h1>
</group>
Placed inside a node, automatically offsets edges to a their position inside the nodes html [Ports demo].
Create a label node that is positioned along an edge
<v-label :edge="graph.edges[0]" :perc="50" :offset="{x: 0, y: -50}">
<h4>Content</h4>
</v-label>
Can be used to store edges and nodes. Contains utility methods to build graphs, layouts, remove and create nodes, edges and so on.
The simplest way to style nodes and edges is using CSS
<style>
svg .node .content {
border-radius: 50%;
background-color: red;
}
svg .edge {
stroke-width: 10;
stroke: blue;
marker-start: url(#arrow-start);
}
</style>
