Events

`

`js
function onData(event) {
const total = event.detail.total;
console.log(${total} activities in the last year);
}
document.querySelector('#activity').addEventListener('data', onData);
`

Use As Image

It is also possible to insert Activity widget as an image. It is useful in places where you can't integrate web component, or for example on your GitHub profile README.md page.

Image URL is the following:

`
https://cr-ss-service.azurewebsites.net/api/ScreenShot?widget=activity&username=YOUR_USERNAME
`

It accepts all widget attributes as query string parameters, plus one extra parameter:

| Name | Type | Default | Description |
| ------- | -------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| width | number | 800 | Width of widget element (generated image). Note that generated image has @2x pixel density, so the PNG image will be actually generated in @2x size from the one specified here |
| style | string | | style attribute value (here you can specify all CSS variables) |

For example:

`html
src="https://cr-ss-service.azurewebsites.net/api/ScreenShot?widget=activity&username=YOUR_USERNAME&labels=true"
/>
`

Note that you need to URL Encode some of the characters, for example # should be %23 and #ff0 color should be specified as %23ff0` in query.
