Tars.js is a meta-repository that aggregates multiple submodules to provide a framework for building Node.js services in a Tars-based heterogeneous system. The framework enables non-intrusive integration with existing Node.js applications, offering features such as multi-process management, logging, monitoring, RPC, dynamic configuration, and alerting. The actual implementation of these features resides in the linked submodules (e.g., @tars/rpc, @tars/logs), while this repository serves as a central point for managing the submodule versions and providing documentation. The provided source files in this repository consist only of metadata (.gitmodules, LICENSE, READMEs) and do not contain the framework's implementation code.
