How to make use of it:

Install & Download:

$ npm install drawflow --save

1. Import the draw flow as the ES module.

import Drawflow from 'drawflow'
import styleDrawflow from 'drawflow/dist/drawflow.min.css'

2. Or Load the Drawflow’s JavaScript and CSS records data within the doc.

<link rel="stylesheet" href="/path/to/dist/drawflow.min.css"> <script src="/path/to/dist/drawflow.min.js"></script>

3. Create a container in the place you need to render the flowchart.

<div id="drawflow"></div>

4. Initialize the flowchart builder.

var example = document.getElementById("drawflow");
const editor = new Drawflow(example);

5. Start modifying the flowchart.


6. add nodes to the flowchart.

editor.addNode(name, inputs, outputs, posx, posy, class, data, html);

7. Register reusable nodes.

var html = document.createElement("div");
html.innerHTML =  "Hello World!";
editor.registerNode('myNode', html);
editor.addNode('newNode', 0, 1, 150, 300, 'newNode', data, 'myNode', true);

8. Export & import chart data.

var exportdata = editor.export();

9. Disable the editor mode.

editor.editor_mode = 'fixed';

10. Adjust the min/max zoom components.

editor.zoom_max = 1.6;
editor.zoom_min = 0.5;

11. More API strategies.

// remove a node

// add a connection
editor.addConnection(id_output, id_input, output_class, input_class)

// remove connection
editor.removeSingleConnection(id_output, id_input, output_class, input_class)

// add input to node

// add output to node

// remove input from node.
editor.removeNodeInput(id, input_class)

// remove output from node
editor.removeNodeOutput(id, output_class)

// remove a collection between nodes

// clear the data of the selected node

// clear all data

// zoom in/out

12. Event handlers.

editor.on('nodeCreated', function(id) {
  // do something

editor.on('nodeRemoved', function(id) {
  // do something

editor.on('nodeSelected', function(id) {
  // do something

editor.on('connectionCreated', function(ouput_id, input_id, ouput_class, input_class) {
  // do something

editor.on('connectionRemoved', function(ouput_id, input_id, ouput_class, input_class) {
  // do something

editor.on('moduleCreated', function(name) {
  // do something

editor.on('moduleChanged', function(name) {
  // do something

editor.on('mouseMove', function(x, y) {
  // do something

editor.on('zoom', function(zoom_level) {
  // do something

editor.on('translate', function(x, y) {
  // do something

editor.on('import', function() {
  // do something
