[GitHub] [echarts] iuliust opened a new issue #15284: Some of Echarts' internal types should be exported (eg: ElementEvent)
iuliust opened a new issue #15284:
URL: https://github.com/apache/echarts/issues/15284
### Version
5.1.2
### Steps to reproduce
Try to get a reference to the ElementEvent type of echartsInstance.on(eventName, (event) => {...})
### What is expected?
In a typescript project, we should be able to get the reference to the ElementEvent type, among other types.
### What is actually happening?
There's no way to get a clean reference to the type
---
In general, a very, very limited part of Echarts' internal types are exported. This is a big problem, because when I want to declare an observable of ElementEvent, it is just impossible.
I want to be able to have the following code :
```typescript
import { ElementEvent } from 'echarts';
// ...
export class ChartComponent {
chartClickEvents = new Subject<ElementEvent>(); // Unfortunately, it's impossible because Echart's types are almost never exported...
constructor() {
// ...
this.echartsInstance.on('click', event => {
this.chartClickEvents.next(event);
});
this.chartClickEvents.pipe(
tap(e => {
// do stuff...
}),
).subscribe();
}
}
```
