Class NgrokInstaller

java.lang.Object

com.github.alexdlaird.ngrok.installer.NgrokInstaller

public class NgrokInstaller
extends java.lang.Object

A helper for downloading and installing the ngrok for the current system.

Config File

By default, ngrok will look for its config file in the home directory’s .ngrok2 folder. We can override this behavior with JavaNgrokConfig.Builder.withConfigPath(Path).

Binary Path

The java-ngrok package manages its own ngrok binary. We can use our ngrok binary if we want by setting it with JavaNgrokConfig.Builder.withNgrokPath(Path) and passing that config to NgrokClient.
