  1. trait Assert extends Object with IEventEmitter

    The assert module provides a simple set of assertion tests that can be used to test invariants.

    The assert module provides a simple set of assertion tests that can be used to test invariants. The module is intended for internal use by Node.js, but can be used in application code via require('assert'). However, assert is not a testing framework, and is not intended to be used as a general purpose assertion library.

    The API for the assert module is Locked. This means that there will be no additions or changes to any of the methods implemented and exposed by the module.

  2. class Console extends Object

    The console module provides a simple debugging console that is similar to the JavaScript console mechanism provided by web browsers.

    The console module provides a simple debugging console that is similar to the JavaScript console mechanism provided by web browsers.

    The module exports two specific components:

    • A Console class with methods such as console.log(), console.error() and console.warn() that can be used to write to any Node.js stream.
    • A global console instance configured to write to stdout and stderr. Because this object is global, it can be used without calling require('console').

  5. class Error extends Object

    Creates a new Error object and sets the error.message property to the provided text message.

    Creates a new Error object and sets the error.message property to the provided text message. If an object is passed as message, the text message is generated by calling message.toString(). The error.stack property will represent the point in the code at which new Error() was called. Stack traces are dependent on V8's stack trace API. Stack traces extend only to either (a) the beginning of synchronous code execution, or (b) the number of frames given by the property Error.stackTraceLimit, whichever is smaller.

  18. trait Global extends Object

    In browsers, the top-level scope is the global scope.

    In browsers, the top-level scope is the global scope. That means that in browsers if you're in the global scope var something will define a global variable. In Node.js this is different. The top-level scope is not the global scope; var something inside an Node.js module will be local to that module.

  19. trait Module extends Object

    In each module, the module free variable is a reference to the object representing the current module.

    In each module, the module free variable is a reference to the object representing the current module. For convenience, module.exports is also accessible via the exports module-global. module isn't actually a global but rather local to each module.

  1. val FatalError: ExitCode

    There was a fatal unrecoverable error in V8.

    There was a fatal unrecoverable error in V8. Typically a message will be printed to stderr with the prefix FATAL ERROR.

  2. val InternalExceptionHandlerRunTimeFailure: ExitCode

    There was an uncaught exception, and the internal fatal exception handler function itself threw an error while attempting to handle it.

    There was an uncaught exception, and the internal fatal exception handler function itself threw an error while attempting to handle it. This can happen, for example, if a 'uncaughtException' or domain.on('error') handler throws an error.

  3. val InternalJavaScriptEvaluationFailure: ExitCode

    The JavaScript source code internal in Node.js's bootstrapping process failed to return a function value when evaluated.

    The JavaScript source code internal in Node.js's bootstrapping process failed to return a function value when evaluated. This is extremely rare, and generally can only happen during development of Node.js itself.

  4. val InternalJavaScriptParseError: ExitCode

    The JavaScript source code internal in Node.js's bootstrapping process caused a parse error.

    The JavaScript source code internal in Node.js's bootstrapping process caused a parse error. This is extremely rare, and generally can only happen during development of Node.js itself.

  5. val InternalJavaScriptRunTimeFailure: ExitCode

    The JavaScript source code internal in Node.js's bootstrapping process threw an error when the bootstrapping function was called.

    The JavaScript source code internal in Node.js's bootstrapping process threw an error when the bootstrapping function was called. This is extremely rare, and generally can only happen during development of Node.js itself.

  6. val InvalidArgument: ExitCode

    Either an unknown option was specified, or an option requiring a value was provided without a value.

  7. val InvalidDebugArgument: ExitCode

    The --debug and/or --debug-brk options were set, but an invalid port number was chosen.

  8. val NonFunctionInternalExceptionHandler: ExitCode

    There was an uncaught exception, but the internal fatal exception handler function was somehow set to a non-function, and could not be called.

  9. val SignalExits: ExitCode

    If Node.js receives a fatal signal such as SIGKILL or SIGHUP, then its exit code will be 128 plus the value of the signal code.

    If Node.js receives a fatal signal such as SIGKILL or SIGHUP, then its exit code will be 128 plus the value of the signal code. This is a standard Unix practice, since exit codes are defined to be 7-bit integers, and signal exits set the high-order bit, and then contain the value of the signal code.

  10. val UncaughtFatalException: ExitCode

    There was an uncaught exception, and it was not handled by a domain or an 'uncaughtException' event handler.

  11. def __dirname: String

    The directory name of the current module.

    The directory name of the current module. This the same as the path.dirname() of the __filename.

  12. def __filename: String

    The file name of the current module.

    The file name of the current module. This is the resolved absolute path of the current module file. For a main program this is not necessarily the same as the file name used in the command line. See __dirname for the directory name of the current module.
