ilueckel opened a new issue #13755:
URL: https://github.com/apache/incubator-echarts/issues/13755
### What problem does this feature solve?
The `init` function returns a class of type `ECharts`. This works fine as
long as you use the chart variable right after initalization.
```ts
import {init, EChartsOption} from "echarts";
...
export class BaseChart {
initChart() {
const chart = init(nativeElement);
// do something else with the chart.
}
}
```
But all typings get lost, when you want to pass the chart around (e.g. for
updating data later on)
```ts
import {init, EChartsOption} from "echarts";
...
export class BaseChart {
const chart: ECharts; // <--- This does not work. You can it make `any`,
but then all typings are lost;
initChart() {
this.chart = init(nativeElement);
// do something else with the chart.
}
}
```
The TypeScript definitions do not export the `ECharts` class
```ts
import {ECharts} from "echarts" // <---- This is not possible
```
### What does the proposed API look like?
Extend the exports in TypeScript. Something like this:
```
export { ECharts, EChartsFullOption as EChartsOption, connect, disConnect,
dispose, getInstanceByDom, getInstanceById, getMap, init, registerLocale,
registerMap, registerTheme };
```
