async function screenshotsPerSecond() {
const context = await createContext(document.querySelector('#app'), {
workerUrl,
workerNumber: 1,
})
for (let i = 0; i < 10; i++) {
domToPng(context).then(dataUrl => {
const link = document.createElement('a')
link.download = screenshot-${ i + 1 }.png
link.href = dataUrl
link.click()
if (i + 1 === 10) {
destroyContext(context)
}
})
await new Promise(resolve => setTimeout(resolve, 1000))
}
}
