downloads	Downloads

For every attachment downloaded by the page, [event: Page.download] event is emitted. All these attachments are downloaded into a temporary folder. You can obtain the download url, file system path and payload stream using the [Download] object from the event.

You can specify where to persist downloaded files using the [option: downloadsPath] option in [method: BrowserType.launch].

:::note Downloaded files are deleted when the browser context that produced them is closed. :::

Here is the simplest way to handle the file download:

// Start waiting for download before clicking. Note no await.
const downloadPromise = page.waitForEvent('download');
await page.getByText('Download file').click();
const download = await downloadPromise;
// Wait for the download process to complete
console.log(await download.path());
// Save downloaded file somewhere
await download.saveAs('/path/to/save/download/at.txt');

// Wait for the download to start
Download download = page.waitForDownload(() -> {
    // Perform the action that initiates download
    page.getByText("Download file").click();
});
// Wait for the download process to complete
Path path = download.path();
System.out.println(download.path());
// Save downloaded file somewhere
download.saveAs(Paths.get("/path/to/save/download/at.txt"));

# Start waiting for the download
async with page.expect_download() as download_info:
    # Perform the action that initiates download
    await page.get_by_text("Download file").click()
download = await download_info.value
# Wait for the download process to complete
print(await download.path())
# Save downloaded file somewhere
await download.save_as("/path/to/save/download/at.txt")

# Start waiting for the download
with page.expect_download() as download_info:
    # Perform the action that initiates download
    page.get_by_text("Download file").click()
# Wait for the download to start
download = download_info.value
# Wait for the download process to complete
print(download.path())
# Save downloaded file somewhere
download.save_as("/path/to/save/download/at.txt")

// 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
Console.WriteLine(await download.PathAsync());
// Save downloaded file somewhere
await download.SaveAsAsync("/path/to/save/download/at.txt");

Variations

If you have no idea what initiates the download, you can still handle the event:

page.on('download', download => download.path().then(console.log));

page.onDownload(download -> System.out.println(download.path()));

async def handle_download(download):
    print(await download.path())
page.on("download", handle_download)

page.on("download", lambda download: print(download.path()))

page.Download += (sender, download) => Console.WriteLine(download.Url);

Note that handling the event forks the control flow and makes the script harder to follow. Your scenario might end while you are downloading a file since your main control flow is not awaiting for this operation to resolve.
