Function basicLogger

Provides a simple [[LDLogger]] implementation.

This logging implementation uses a simple format that includes only the log level and the message text. By default, output is written to console methods (console.info for normal informational messages, console.warn for warnings, console.error for errors, and console.log for debug output) and the default minimum level is info (that is, debug output is suppressed). You can filter by log level or change the output destination with [[BasicLoggerOptions]].

To use the logger created by this function, put it into [[LDOptions.logger]]. If you do not set [[LDOptions.logger]] to anything, the SDK uses a default logger that is equivalent to ld.basicLogger({ level: 'info' }).

Example

This example shows how to use basicLogger in your SDK options to enable console logging only at warn and error levels.

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