|
|
`maxGraph` is a TypeScript library which can display and allow interaction with vector diagrams. At a high level, it provides:
|
|
- **Nodes**, also known as **vertices** which are typically represented by shapes like rectangles.
|
|
- **Edges** which can be lines and arrows which normally point between one node and another.
|
|
|
|
It provides many of the diagramming features which would be expected by a piece of presentation software like Microsoft® PowerPoint™
|
|
or LibreOffice® Impress such as being able to resize, move or rotate nodes, but has a stronger focus on automatic layout
|
|
algorithms and applications of [Graph Theory](https://en.wikipedia.org/wiki/Graph_theory). It is suited towards software
|
|
which requires finer-grained customization of functionality than off-the-shelf packages.

|
|
|
|
|
|
The `maxGraph` library uses no third-party software, it requires no plugins and can be integrated in virtually any framework (it's vanilla JS).
|
|
|
|
`maxGraph` is the successor of [mxGraph](https://github.com/jgraph/mxgraph) which is now end of life.
|
|
At first, it provides the same features as `mxGraph` and adds
|
|
- TypeScript support
|
|
- maintained npm package
|
|
- modern modular, tree shakable, version of `mxGraph` to reduce the whole package size
|
|
|
|
New features will follow.
|
|
|
|
|
|
## Browser support
|
|
|
|
Chrome, Edge, Firefox, Safari, Chromium based browsers (Brave, Opera, ....) for mobile and desktop.
|
|
|
|
## Project status
|
|
|
|
`maxGraph` is under active development and is in **alpha**. Please try it in your application and [submit an issue](https://github.com/maxGraph/maxGraph/issues)
|
|
if you think that something is not working.
|
|
|
|
You can also test `maxGraph` by running the [Storybook examples](#development) or [build the npm package locally](#build-local-npm-package) to get the latest changes.
|
|
|
|
## Install
|
|
|
|
Install the latest version of `maxGraph` from the [npm registry](https://www.npmjs.com/package/@maxgraph/core).
|
|
|
|
npm
|
|
```
|
|
npm install @maxgraph/core
|
|
```
|
|
|
|
yarn
|
|
```
|
|
yarn add @maxgraph/core
|
|
```
|
|
|
|
pnpm
|
|
```
|
|
pnpm add @maxgraph/core
|
|
```
|
|
|
|
## Getting Started
|
|
|
|
Assuming your page defines an element with the id `graph-container`, the following will display a rectangle connected to an orange circle.
|
|
```typescript
|
|
import {type CellStyle, Graph, InternalEvent} from '@maxgraph/core';
|
|
|
|
const container = <HTMLElement>document.getElementById('graph-container');
|
|
// Disables the built-in context menu
|
|
InternalEvent.disableContextMenu(container);
|
|
|
|
const graph = new Graph(container);
|
|
graph.setPanning(true); // Use mouse right button for panning
|
|
// Gets the default parent for inserting new cells. This
|
|
// is normally the first child of the root (ie. layer 0).
|
|
const parent = graph.getDefaultParent();
|
|
|
|
// Adds cells to the model in a single step
|
|
graph.batchUpdate(() => {
|
|
const vertex01 = graph.insertVertex({
|
|
parent,
|
|
position: [10, 10],
|
|
size: [100, 100],
|
|
value: 'rectangle',
|
|
});
|
|
const vertex02 = graph.insertVertex({
|
|
parent,
|
|
position: [350, 90],
|
|
size: [50, 50],
|
|
style: {
|
|
fillColor: 'orange',
|
|
shape: 'ellipse',
|
|
verticalAlign: 'top',
|
|
verticalLabelPosition: 'bottom',
|
|
},
|
|
value: 'ellipse',
|
|
});
|
|
graph.insertEdge({
|
|
parent,
|
|
source: vertex01,
|
|
target: vertex02,
|
|
value: 'edge',
|
|
style: {
|
|
edgeStyle: 'orthogonalEdgeStyle',
|
|
rounded: true,
|
|
},
|
|
});
|
|
});
|
|
```
|
|
|
|
You will see something like in the following _maxGraph panning_ demo:
|
|
|
|
|
|
|
|
For more details, have a look at the [storybook stories](packages/html/stories).
|
|
|
|
Notice that some elements produced by `maxGraph` require to use [CSS and images](packages/website/docs/usage/css-and-images.md) provided in the npm package.
|
|
|
|
|
|
## TypeScript support
|
|
|
|
`maxGraph` is written in TypeScript and provides type definitions so `maxGraph` can be easily integrated into TypeScript applications.
|
|
|
|
`maxGraph` requires **TypeScript 3.8** or greater.
|
|
|
|
## Support
|
|
|
|
For usage question, please open a new [discussion](https://github.com/maxGraph/maxGraph/discussions/categories/q-a) on GitHub. You can also use
|
|
[GitHub discussions](https://github.com/maxGraph/maxGraph/discussions) for other topics like `maxGraph` development or to get the latest news.
|
|
|
|
Until we provide a complete documentation, you can check the mxGraph resources
|
|
- mxGraph documentation: [Github pages branch](https://jgraph.github.io/mxgraph/). The key resources are the JavaScript user manual, the JavaScript examples and the JavaScript API specification.
|
|
- [mxgraph tag on Stack Overflow](http://stackoverflow.com/questions/tagged/mxgraph). Please ensure your questions adhere to the [SO guidelines](http://stackoverflow.com/help/on-topic), otherwise it is likely to be closed.
|
|
|
|
|
|
## Migrating from mxGraph
|
|
|
|
`maxGraph` APIs are not fully compatible with `mxGraph` APIs. The concepts are the same, so experienced `mxGraph` users should be able to switch from `mxGraph` to `maxGraph` without issues.
|
|
|
|
For a complete guide, see the [dedicated migration page](packages/website/docs/usage/migrate-from-mxgraph.md).
|
|
|
|
|
|
## History
|
|
|
|
On 2020-11-09, the development on `mxGraph` stopped and `mxGraph` became effectively end of life.
|
|
|
|
On 2020-11-12, a fork of the `mxGraph` was created with a call to Contributors.
|
|
|
|
> 12 Nov 2020.
|
|
>
|
|
> If you are interested in becoming a maintainer of mxGraph please comment on issue [#1](https://github.com/maxGraph/maxGraph/issues/1)
|
|
>
|
|
> Initial objectives:
|
|
>
|
|
> - The first priority is to maintain a working version of mxGraph and its **npm package**
|
|
> - The ambitious stretch goal is to refactor the codebase to create a modern modular, tree shakable, version of mxGraph to reduce the whole package size.

The project was then [renamed on 2021-06-02](https://github.com/maxGraph/maxGraph/discussions/47) into `maxGraph` due to [licensing issue](https://github.com/maxGraph/maxGraph/discussions/23).
|
|
|
|
Starting from the `mxGraph` 4.2.2 release, we
|
|
- moved code to ES9
|
|
- removed Internet Explorer specific code
|
|
- migrated to TypeScript, based on the work initiated in [typed-mxgraph](https://github.com/typed-mxgraph/typed-mxgraph)
|
|
- migrated the examples to [Storybook](https://storybook.js.org/)
|
|
|
|
|
|
## Development
|
|
|
|
### Clean former mxGraph tags
|
|
|
|
Ensure you don't have the former `mxGraph` tags locally (see [#92](https://github.com/maxGraph/maxGraph/issues/92) fore more details):
|
|
```
|
|
git fetch --all --tags --prune
|
|
```
|
|
|
|
### Setting up local development environment
|
|
|
|
NodeJS requirements:
|
|
- use the version declared in [.nvmrc](./.nvmrc). Other versions may work but are not supported.
|
|
- this is the version used by GitHub Actions
|
|
- nvm users can run `nvm use`. If the Node version is not installed, nvm will state how to install the required version.
|
|
|
|
|
|
In the project root directory, execute
|
|
|
|
```sh
|
|
$ npm install
|
|
```
|
|
|
|
In the `packages/core` folder, execute
|
|
|
|
```sh
|
|
npm pack
|
|
```
|
|
|
|
To watch the core package, execute (in the project root directory)
|
|
|
|
```sh
|
|
$ npm run dev
|
|
```
|
|
|
|
and select `@maxgraph/core`.
|
|
|
|
To run the html(vanilla-js) version of [Storybook](https://storybook.js.org/), execute (in the project root directory)
|
|
|
|
```sh
|
|
$ npm run dev
|
|
```
|
|
|
|
and select `@maxgraph/html`.
|
|
|
|
Since both commands are in watch mode, so it's recommended to open two terminals and run them separately. When a file is saved from the core package, the html storybook will be automatically updated.
|
|
|
|
|
|
### <a id="build-local-npm-package"></a> Building the npm package locally
|
|
|
|
**Reminder**: the released version are available at [npmjs](https://www.npmjs.com/package/@maxgraph/core).
|
|
|
|
Run
|
|
- from the project root: `npm install`
|
|
- then, from the `packages/core` folder: `npm pack`
|
|
|
|
The `packages/core` folder or the generated `packages/core/maxgraph-core-***.tgz` file are now ready for use in your application, using [npm link](https://docs.npmjs.com/cli/v8/commands/npm-link) or `npm install`.
|
|
|
|
Examples of use can be found in the [maxgraph-integration-examples](https://github.com/maxGraph/maxgraph-integration-examples) repository.
|
|
|
|
