Class console

Ta klasa umożliwia programiście zapisywanie logów w usłudze Stackdriver Logging w Google Cloud Platform. Poniżej Oto kilka przykładów logowania:

function measuringExecutionTime() {
  // A simple INFO log message, using sprintf() formatting.
  console.info('Timing the %s function (%d arguments)', 'myFunction', 1);

  // Log a JSON object at a DEBUG level. If the object contains a property called "message",
  // that is used as the summary in the log viewer, otherwise a stringified version of
  // the object is used as the summary.
  var parameters = {
    isValid: true,
    content: 'some string',
    timestamp: new Date()
  };
  console.log(parameters);

  var label = 'myFunction() time';  // Labels the timing log entry.
  console.time(label);              // Starts the timer.
  try {
    myFunction(parameters);         // Function to time.
  } catch (e) {
    // Logs an ERROR message.
    console.error('myFunction() yielded an error: ' + e);
  }
  console.timeEnd(label);      // Stops the timer, logs execution duration.
}
