Function basicLogger

Provides a basic LDLogger implementation.

Output is written to console.log using Node's util.format so multiple arguments and format specifiers (%s, %d, etc.) are formatted the way Node consumers expect.

If you do not pass a logger via LDOptions.logger, the SDK falls back to a logger equivalent to basicLogger({ level: 'info' }).

Example

const ldOptions = {
  logger: basicLogger({ level: 'warn' }),
};
