Is there any way to combine the two loggers together? I wish that the logger file will combine from the express transformation information, and from the other information I want logger. This will set up Winston to write a log to the console as well as a file.

Then you can use the last expression to pass output from the morgan middleware into winston. However, it is important to note that there is a slight difference between our codes.

What's the point of doing this, I mean, why did you need morgan at the beggining, why not just write a winston middlewrare for express? Active Oldest Votes. This article does an excellent job for what you want to do. Shay Erlichmen Can we use a timestamp in this process? It doesn't seem like it's necessary to override logger.

NPM - Do better than officeconnecttuneboss.online

In my case, I was able to do app. If you're using DevonSams's method, you'll get an empty line between logged lines because both morgan and winston are adding a linebreak in the end of the logged message.

You can simply trim the linebreak out from the message with logger. What if I want to use logger. Consolenew winston.

Why tiny and not combined? I wasn't able to get this to work anymore. It seems like the typeings are incorrect. Update the last line to remove warning app. Johnny Johnny 71 1 1 silver badge 1 1 bronze badge.The console module is usually the first tool Node.

But then you might stumble upon a logging framework like Winston or Bunyan.

The basic power of those tools might be attractive enough for you to consider switching. But should you? How do you know which one you should use? Should basic console. Side note: above console refers to the global console, but it is possible to import console as a Class, which you can then instantiate to configure your own output streams rather than just stdout and stderr.

From the above, console seems like it should get the job done, so why would we even consider something else? While it already has what appear to be log levels see belowthese are really just functions that route to stdout and stderr without providing true log levels. Popular Node logging frameworks like Winston and Bunyan allow for log levels, easy toggling logs on and off based on environment, and sometimes in the case of Winston support for custom log levels that you as a developer can define.

For example, you can configure Winston or Bunyan to write to stdout, a file, and a database all at once. Side note: this ability to write to multiple different outputs, however, is a feature I would recommend against using. The full explanation why is not within the scope of this post, and I will write a new one in the future with a more complete explanation, but for now know that the reason is to keep log routing separate from your application code.

Your DevOps team is sick of sifting through so many logs in production and only care about the errors. And your dev team wants to log results from a particular function call to a specific level that they can keep an eye on in while testing. So, why might you not want to use a logging framework? When would vanilla console do?

They also might just be overkill for your scenario. Only reach for a logging framework if you have requirements that warrant it.

We are, after all, just creating a quick test project. We are now positioned to install Winston and save it as a dependency in our package. This enables us to log messages to the console by defining a "transport" in Winston parlance to specify where we want to output our messages.

We use require to load the Winston module and we can then start logging messages to the console. As noted in the program comments above, we can also change the format of the log output messages and use JSON rather than the simple format. We'll talk about this more later in the article. By default, Winston uses logging levels utilized by npm:. Let's take our previous example and log a message using the silly logging threshold:.

We must also change the level property in our createLogger options parameter to increase our logging threshold from debug to silly and enable the silly logging level to be logged to the output.

Let's do that now:. Logging levels can be very helpful to us. We could, for example, choose to dial back the level property to a different logging threshold such as warn if we only wanted to emit logging messages that are warn or lower which would include error to view a smaller subset of logging messages. Here's how it's done:.

In this example, we modify the Winston "transport" for the console to add an additional format. To utilize multiple formats, Winston requires that we wrap the format functions inside a format. Run this example, and you will see colorized output in your console that varies by the logging level of the message. Adding a timestamp to each log entry will prove to be very useful for IoT applications—or any application for that matter.

Here's the code needed to bring timestamps to life:. To enable timestamps to appear in the log entry, we change our format from format. We also add the second transport for a file. Notice also that we can specify different levels thresholds for our transports. In this context, if we are running in a development environment, we use a level of debug and thus send more messages to the log file than we send to the console which is configured with a level of info. When you run this code, you should see a log file get created before your eyes.

Feel free to experiment with the levels when writing log entries and see how the log output varies between the console and the log file.

We can also tailor the individual transports to log to the console using standard text format and log to a file using JSON format. In this case, we change the global value for log format to format. This same functionality can be accomplished other ways including through the use of the logrotate command in the Linux world; however, we will demonstrate a way to make this happen here in the context of Winston.

We will first install the winston-daily-rotate-file package from npm using the following command:. In this code example, we change our file transport to use the winston-daily-rotate-file transport that we installed above. When instantiating the dailyRotateFileTransport we are also able to supply options to control the format and location of our log file.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
