trait Util extends Object

These functions are in the module 'util'. Use require('util') to access them. The util module is primarily designed to support the needs of Node.js's internal APIs. Many of these utilities are useful for your own programs. If you find that these functions are lacking for your purposes, however, you are encouraged to write your own utilities. We are not interested in any future additions to the util module that are unnecessary for Node.js's internal functionality.

  7. def debuglog(section: String): Function

    This is used to create a function which conditionally writes to stderr based on the existence of a NODE_DEBUG environment variable.

    This is used to create a function which conditionally writes to stderr based on the existence of a NODE_DEBUG environment variable. If the section name appears in that environment variable, then the returned function will be similar to console.error(). If not, then the returned function is a no-op.

    Example:

    1. util.debuglog(section)

  8. def deprecate(function: Function, message: String, code: String = js.native): Any

    Marks that a method should not be used any more.

    1. util.deprecate(function, message)

  17. def inherits(constructor: Any, superConstructor: Any): Any

    Inherit the prototype methods from one constructor into another.

    Inherit the prototype methods from one constructor into another. The prototype of constructor will be set to a new object created from superConstructor.

    As an additional convenience, superConstructor will be accessible through the constructor.super_ property.

    Example:

    1. util.inherits(constructor, superConstructor)
