# dagre-d3-es
|
|
|
|
The [dagre-d3](https://github.com/dagrejs) library is not maintained anymore.
|
|
|
|
[dagre-d3-es](https://www.npmjs.com/package/dagre-d3-es) is a fork using the more modern ES6 javascript syntax.
|
|
It uses [ES](https://262.ecma-international.org/6.0/) modules, thus the name [dagre-d3-es](https://www.npmjs.com/package/dagre-d3-es).
|
|
|
|
[dagre-d3-es](https://www.npmjs.com/package/dagre-d3-es) follows [d3](https://www.npmjs.com/package/d3) versions. Ex: dagre-d3-es version 7 depends on [d3](https://www.npmjs.com/package/d3) version 7.

## Code example
|
|
|
|
Coming from the legacy `dagre-d3`, the main changes in your code will be:
|
|
|
|
```
|
|
import * as dagreD3 from 'dagre-d3-es';
|
|
...
|
|
const g = new dagreD3.graphlib.Graph().setGraph({});
|
|
...
|
|
const zoom = d3.zoom().on('zoom', (zoomEvent) => {
|
|
inner.attr('transform', zoomEvent.transform);
|
|
});
|
|
|
|
```
