A tiny JavaScript debugging utility modeled after Node.js core's debugging technique that exposes namespaced debug loggers controlled via the DEBUG environment variable. It works in both Node.js and web browsers, with color-coded output per namespace.

Use cases

• add toggleable debug logging to a node.js app
• filter debug output by module namespace
• debug javascript code in the browser
• replace console.log with controllable debug statements
• color-code log output per module
• enable verbose logging via environment variable

When to choose

• you want lightweight, zero-config debug logging in Node.js or the browser
• you need fine-grained control over which modules emit debug output
• you want a battle-tested utility used across the npm ecosystem

When to avoid

• you need structured logging, log levels, or log shipping to external systems
• you want a full logging framework with file output and rotation
• you need production observability like tracing or metrics
