NodeLine is a JavaScript library for creating dynamic connections between graphical elements.
The NodeLine library offers a simple and flexible way to add connection functionalities between elements in JavaScript projects. With this library, you can create dynamic visual lines to connect different elements, enabling an interactive and intuitive experience for users.
- Rendering a line between selected elements.
- Support for different types of elements such as text boxes, images, and custom shapes.
Import the library into your project/file.js
import { NodeLine } from "node-line.main.js";When importing the library into your project, instantiate the NodeLine class, and you can assign each instance to a constant :
const myNode = new NodeLine()After doing that, you should pass the required arguments :
const myNode = new NodeLine(elementA,elementB,elementRender);- elementA ( The element where the starting point A of the line begins. )
- elementB ( The element where the ending point B of the line terminates )
- elementRender ( The container where the line should be rendered. ex: ... )
After doing that, you should invoke the function that creates the line :
myNode.createNode();If you are assigning NodeLine to an element with dynamic proportion or displacement, such as DnD, you should call the function that updates the line whenever there is any event. :
myNode.updatePath();Now it's possible to remove specific nodes by calling the 'removeNode()' function.
myNode.removeNode();To customize your line or the starting and ending points of the line, you can call the 'settings()' function.
myNode.settings(line,dot);| Element | key | Type | Description |
|---|---|---|---|
| line | color | string | change the color of line |
| line | scale | string | change the scale / width of line |
| dot | color | string | change the fill color of dot |
| dot | scale | string | change the scale of dot |
| dot | visible | boolean | change if the dot is visible |
'settings()' function example :
mynode.settings({color: "red", scale: "10"},{color: "green", scale: "5",visible: false})Create an 'index.html' file and an 'index.js' file, and then include the 'index.js' file in your 'index.html' file.
Afterward, add two elements, A and B, to your HTML :
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>NodeLine Example</title>
</head>
<body>
<!-- ... -->
<div id="my-element-a"></div>
<div id="my-element-b"></div>
<!-- ... -->
<script type="module" src="index.js"></script>
</body>
</html>In your 'index.js' file, import the 'NodeLine' library, add your HTML elements, and instantiate the 'NodeLine()' class with your arguments :
import { NodeLine } from "node-line.main.js";
const myElementA = document.getElementById("my-element-a");
const myElementB = document.getElementById("my-element-b");
const body = document.body;
const myNode = new NodeLine(myElementA,myElementB,body)In this example, we used const body = document.body to obtain a reference to the 'body' tag and add NodeLine to the body. However, you can use any other supported element as the container.
