Defender Serverless Plugin is an evolving Serverless Framework solution designed for automated resource management on Defender. It allows developers to declaratively manage Defender resources such as Autotasks, Sentinels, Notifications, Relayers, Contracts, Policies, and Secrets directly through serverless.yml, leveraging the Serverless CLI for deployment. With SSOT (Single Source of Truth) mode, the plugin ensures synchronization between defined and deployed resources, removing discrepancies while safeguarding critical elements like Relayers. Installation is streamlined via a pre-configured template or direct integration into existing projects with yarn, requiring access to the GitHub repository. The plugin facilitates seamless deployment management, resource information retrieval, and structured error handling, key to enhancing operational efficiency in web3 environments. Users are advised to manage Defender Team API keys securely and adjust serverless.yml configurations for optimal deployment outcomes. Caution is warranted as the plugin is under active development, with expected bugs.
