# ConsoleLogger

# Class: ConsoleLogger

Defined in: [packages/typescript/ai/src/logger/console-logger.ts:25](https://github.com/TanStack/ai/blob/main/packages/typescript/ai/src/logger/console-logger.ts#L25)

Pluggable logger interface consumed by every `@tanstack/ai` activity when `debug` is enabled. Supply a custom implementation via `debug: { logger }` on `chat()`, `summarize()`, `generateImage()`, etc. The four methods correspond to log levels: use `debug` for chunk-level diagnostic output, `info`/`warn` for notable events, `error` for caught exceptions.
