Learn how to add and configure winston, a Node.js logger and log HTTP startup messages to the terminal in color with timestamps.
- [Instructor] We're gonna add the Winston Logger…to our project and make it available to all our services.…The most practical way to add a logger is…to create a shared logging library.…There's a few reasons for this.…First of all, you can unify the configuration…throughout the entire system.…There's also the prevention of duplication…of code along with configuration,…especially if you have customizations,…which we will.…If you change your mind about…which logging library your using,…a centralized logging library makes it an easy refactor.…Often, logging libraries exist as separate modules…that are included in any projects that need to log.…
In our case, it's not practical to make a separate module,…so instead we'll just create a folder called shared,…under servers.…What should we log?…A good first thing to log with Winston,…is to add a start up logger that declares…when a server is running and on which port.…Let's get started.…From Visual Studio code make sure the terminal's open.…If the logger is still running, press control C to exit.…
