Microservice Foundation

Fathom provides a tightly integrated base to quickly bootstrap your microservice project using best-of-breed components.

Opinionated

• Undertow is the development & deployment engine
• Guice is the dependency injection mechanism
• Guava is the standard library
• Config is the configuration file parser
• Args4j is the command-line parsing framework
• Logback is the logging framework
• SLF4J is the logging facade
• Java 8 is the baseline JVM

The footprint of the Fathom-Core foundation is ~7.5MB.

Modular & Injectable

Fathom features a formal Module specification, Service infrastructure, and dependency injection all combined with Java ServiceLoader to give you ultimate modularity.
