Dolittle is an open-source platform for building microservices. The platform, coded in TypeScript and used with Node.js, bases its structure on DDD (Domain-Driven Design) and CQRS (Command Query Responsibility Segregation) principles. Developers can use Dolittle's CLI to create codebases for their projects, including boilerplate code for services, clients, and APIs. Within this framework, developers can focus on business logic while letting the platform handle scalability and communication between microservices using gRPC or HTTP/REST interfaces. The tooling provided aims to simplify common development tasks like persistence management by integrating with MongoDB natively. Runtime features include event sourcing support and multi-tenancy capabilities out-of-the-box without additional configuration overhead from developers.
