Target-based triggering in Bitrise is a smarter way to run builds based on specific code events happening in your Git repositories. It allows for targeted triggers, simplified configuration, better support for complex projects, increased efficiency, and real-world examples of multitriggering. Key benefits include smart multitriggering, simplified configuration, and better support for complex projects. Target-based triggering enables developers to run multiple workflows or pipelines independently based on conditions they define, making it easier to manage complex configurations.
