Best practice for documents download

[lrnzfrr]

hi, mi focus is connect a button to a method for download documents generated on the fly:

return Button::make(__('Download'))
                                ->icon('cloud-download')
                                ->method('downloadContract', [
                                    'id' => $userContract->id,
                                ])

in Screen class downloadContract can do this?

If you want the "Download" button to be on several screens at once, but execute code as the click was only in one place, there are several ways:

• Use screen inheritance.
• Give the button a formaction instead of a method

If you just want to pass a parameter, it would be like this:

Button::make('Export file')
    ->method('export', [
        'name' => "Any name for file",
    ])
    ->icon('cloud-download')
    ->rawClick()
    ->novalidate(),

and method screen:

/**
 * @return \Symfony\Component\HttpFoundation\StreamedResponse
 */
public function export($name)
{
    return response()->streamDownload(function () {
        $csv = tap(fopen('php://output', 'wb'), function ($csv) {
            fputcsv($csv, ['header:col1', 'header:col2', 'header:col3']);
        });

        collect([
            ['row1:col1', 'row1:col2', 'row1:col3'],
            ['row2:col1', 'row2:col2', 'row2:col3'],
            ['row3:col1', 'row3:col2', 'row3:col3'],
        ])->each(function (array $row) use ($csv) {
            fputcsv($csv, $row);
        });

        return tap($csv, function ($csv) {
            fclose($csv);
        });
    }, "$name.csv");
}
