mxGraph Typescript Declarations For Official mxGraph NPM Package.


  1. Add mxgraph and @typed-mxgraph/typed-mxgraph dependencies to your project:


     npm install --save mxgraph
     npm install --save-dev @typed-mxgraph/typed-mxgraph


    yarn add mxgraph
    yarn add --dev @typed-mxgraph/typed-mxgraph
  2. Update tsconfig.json append node_modules/@typed-mxgraph to typeRoots:

      "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "esModuleInterop": true,
        "typeRoots": [
  3. Import mxGraph factory:

    import factory from '@realrisman/mxgraph';
    const mx = factory({
      mxBasePath: '',
  4. (optional) Create a helper to import mxgraph

    // src/mxgraph.ts
    import factory from '@realrisman/mxgraph';
    (window as any)['mxBasePath'] = 'assets/mxgraph';
    export default factory({
      // not working see https://github.com/jgraph/mxgraph/issues/479
      mxBasePath: 'assets/mxgraph',
    // src/application.ts
    import mx from './mxgraph';                       // <- import values from factory()
    import { mxGraph, mxGraphModel } from '@realrisman/mxgraph';  // <- import types only
    export class Application {
      constructor(container: HTMLElement) {
        if(mx.mxClient.isBrowserSupported()) {
          console.log('Yes! Yes!');
        const graph: mxGraph = new mx.mxGraph(container);
        const model: mxGraphModel = graph.getModel();
        try {
          graph.insertVertex(graph.getDefaultParent(), '', 'TEST', 0, 0, 100, 100);
        } finally {



Types have been initially created from mxGraph 4.1.0 by hand (1st hosting repository was mxgraph-type-definitions) and progressively updated when new mxgraph versions have been released.

The mxgraph lib is almost fully covered by types in this project. The issues you may encounter are

  • API changes in recent mxgraph have not been reported. We haven't decided how we will manage this in the future, so for now, they are updated when user detect issues
  • Function arguments types or 'mandatoriness' may not be accurate: even by reading the JS code, it is sometimes hard to figure out what is the correct type.
  • Historically, we try to avoid any and use optional when we don't know.
  • We expect user to provide feedbacks by creating GitHub issues and/or Pull Requests when they notice issue with the types.

Implementation Progress

The definitions target mxGraph 4.2.2. See the implementation status in the following table.

  • progress: initial support
    • not yet: no support at all
    • partial: implementation started, but some classes/fields/methods are missing
    • completed: all classes/fields/methods should exist (fill an issue and/or provide a Pull Request if you detect an issue) but
      • TSDoc is not fully accurate
      • some type declaration may be wrong
  • checked: a finest review has been conducted about TSDoc, mxGraph types used by functions/methods, fields, ...
Module Progress Checked
editor partial no
handler completed no
io completed no
layout completed no
model completed no
shape completed no
util partial no
view partial no
mxClient.d.ts completed no
