App description

Scribo is a logging module for Node.js. It can do 2 simple things - log events and measure how long operations take to complete.

You specify the allowed Events in the CONFIG, since each event gets logged to a different file.

API

####Scribo.logEvent(eventName, message, saveable, callback); This outputs:

date time | eventName : message

Event name and message must be strings. Saveable must be a boolean and indicates if the event should be written to its corresponding log file or nor. Callback is optional.

####Scribo.startBench(eventName); Returns an object with the current time which serves as benchmark start.

####Scribo.endBench(eventStart, loggable, callback) Calculates the elapsed time. If loggable is set to TRUE, saves the result to the benchmark's corresponding log file.

Examples

If you want to log events/benchmarks to a file, you need to add each event/benchmark name to the events array. It's located in the EVENTS.js file. The comment in that file has a few examples.

You log an event like that:

http.createServer(function onRequest(req, res) {
  Scribo.logEvent('event name', 'message', false);
  // Request handling...
});

Example benchmark:

let dbWrite = Scribo.startBench('DB write');

DataBase.write(data, function onWriteFinish(err, res) {

  Scribo.endBench(dbWrite, true, function onBenchEnd(err, res) {
    // Handle benchmark ending...
    });

  // Other code...
})
