Download

Download objects are dispatched by page via the Page.Download event.

All the downloaded files belonging to the browser context are deleted when the browser context is closed.

Download event is emitted once the download starts. Download path becomes available once download completes.

// Start the task of waiting for the download before clicking
var waitForDownloadTask = page.WaitForDownloadAsync();
await page.GetByText("Download file").ClickAsync();
var download = await waitForDownloadTask;

// Wait for the download process to complete and save the downloaded file somewhere
await download.SaveAsAsync("/path/to/save/at/" + download.SuggestedFilename);
