Principles

Blindsight has some organizing principles that inform the design.

• Loggers depend directly and solely on the SLF4J API, which can always be accessed directly.
• APIs can be extended or replaced for domain specific logging.
• Knowing when and when not to log is more important than “how fast” you log.
• Loggers can be resolved from user defined context, not simply by name or by class.
• Structured logging is baked in, uses standard Scala idioms, and can be overridden.

Likewise, there are things that Blindsight eschews:

• No effects; logging is always a side effect.
• No constraints or configuration on SLF4J implementation.
• No FP library requirements; no need for scalaz, cats, zio etc.
• No formatting on the front end; messages should not contain JSON/XML.
