xpack/logger-ts

A Node.js CommonJS/ES6 module with a generic console logger class

The GitHub organisation profile is available in the profile/README file.

logger-ts's Issues

_write() should ignore undefined/null messages

The internal _write() functions should validate the input.

Display errors in red

Although I'm not a big fan of the excessively coloured Linux consoles, showing the errors in red might sometimes help. Similarly, warnings in... orange?

Add a method to check if the log level is above a given level

Add isLevel(level), as a generic version of the concrete accessors (like isDebug, etc).

Change the logger constructor to use the generic arguments object

Change to constructor(args).

Also check the pressence of args.console & mandatory members

Add support for directly accessing the console

The current API logs only full lines (adds a line terminator).

For displaying a progress indicator it is necessary to output separate characters, without the terminator.

To avoid complicating the API, probably a good solution is to open access to the underlying console, then directly calling console.log() and console.error() should be enough for the most complicated use cases.

Make the console in the constructor optional

The default is the standard Node.js console.

Change the functions to check the log level to getters

It is debatable, but getters seem easier to use.

The only drawback is that they are prone to typos, not detected by the runtime.

Add a function to test if the level was set

Currently the way to test if the level was set is to read it and check if undefined.

It would be nicer to have a hasLevel() function.

Add defaultLevel
