if (test('[ -d {{release_path}} ]')) {
...
}

upload()

upload($source, string $destination, array $config = []): void

Upload file or directory to host.

You may have noticed that there is a trailing slash (/) at the end of the first argument in the above command, this is necessary to mean “the contents of build“.

The alternative, without the trailing slash, would place build, including the directory, within public. This would create a hierarchy that looks like: {{release_path}}/public/build

The $config array supports the following keys:

• flags for overriding the default -azP passed to the rsync command
• options with additional flags passed directly to the rsync command
• timeout for Process::fromShellCommandline() (null by default)
• progress_bar to display upload/download progress
• `display_stats' to display rsync set of statistics
