BREAKING CHANGES

  • There are no longer any built-in tags added to the tags array for each log message.
  • message.tags is no longer a property of the LogMessage class that can be directly changed.
  • Whenever an Error object is passed into the metadata for a log message, it will automatically be converted to a plain object as stringifying the an Error object will always yield {}.
  • Previously you could directly access the private properties of LogMessage. In order to add some integrity, they are no longer using standard property names starting with an underscore and are instead referenced using symbols instead. For advanced usage, these symbols are exported as a static property on the LogMessage class under LogMessage.symbols.

2.0.0 (7/15/2018)

The new major release for lambda-log which contains many new extensibility features and a handful of new usability features. There are a few breaking changes from version 1.4.0 to keep in mind when migrating. All breaking changes will be noted in the changelog below:

Internal/Module Changes

  • Moved LambdaLog class out of index.js into lib/LambdaLog.js for organization purposes.
  • NEW: Utilize console module (native Node) instead of the global console object for logging. This allows more control of where logs are redirected to for custom advanced integrations.
  • NEW: Log messages are now an instance of the LogMessage class which allows custom methods and better control over log messages.

LambdaLog Class/Configuration

  • NEW: Added ability to configure the logger via the constructor (#3).
  • NEW: Added ability to configure the log levels and methods via the constructor.
  • NEW: Added stdoutStream and stderrStream configuration options to configure the desired output of log messages. By default it redirects to process.stdout and process.stderr.
  • NEW: Added dynamicMeta configuration option which will allow dynamic metadata to be added to each log on creation.
  • NEW: Added replacer configuration option for JSON.stringify.
  • BREAKING: Static method isError() has been moved to the LogMessage class and is no longer accessible in the LambdaLog class.

Logging Functions

  • NEW: All log functions now accept an array of tags to append to a log.
  • FIX: Metadata passed into a log function will now be wrapped in a plain object if the provided value is not an object.
  • BREAKING: All log functions now return an instance of LogMessage instead of a plain log object which allows directly calling additional methods of LogMessage (chaining). See documentation for more information.

Events

  • BREAKING: The log event now provides an instance of LogMessage instead of a plain object.
