Cloud Ready

Services build with Cricket can run on different cloud implementations. Dockerization of services is also an easy task, although not always necessary.

Clear architecture

Implements the "ports and adapters" (hexagonal) architecture pattern. The service is event driven with the smallest necessary dose of dependency injection.

HTTP server

HTTP/S requests handled internally to serve both REST and HTML page calls.

Key-Value database

In-memory, no SQL database can be used for fast prototyping.

Data to JSON serializer

Automatic JSON serialization/deserialization thanks to the json-io project.


One-time or repetitive tasks based on configuration or defined in code.


The StandardLogger (using Java Logger) can be replaced with other adapter of your choice, eg. centralized logging system.


Your service can monitor it's sensitive parameters or external services. Example adapters to monitor memory and disk space are included.

In recent months, Cricket has undergone a lot of changes and gained some interesting features. For this reason, the documentation that has already been created is outdated in many parts.
I will consistently post new articles on the Signocom's blog or in the GitHub repository.
Stay tuned.
