Many client-side libraries already support a JavaScript console object. Since this functionality is useful on the server, and to ease migration of client-side JavaScript to the server, server-side JavaScript platforms need to provide a "console" object suitable for use with minimal modification to existing scripts. Rather than provide a "console" free variable like web browsers, interoperable JavaScript modules may explicitly import the "console" module and bind it to a module local "console" variable.
Specification
The "console" top-level module must be available in all platforms. The module must provide the following exports:
- log(message)
- logs a message
- info(message)
- logs an informational message
- warn(message)
- logs a warning message
- error(message)
- logs an error message
- debug(message)
- logs a debug message
- pass(name)
- logs the success of a test
- fail(name)
- logs the failure of a test
- print(message, [level])
- logs a message. The level may be any of "log", "info", "warn", "error", "debug", "pass", "fail", null, or undefined. Other labels beginning with "x" and a platform-specific identifier are reserved for the corresponding platform.
Messages may be any reference. Names must be strings.
