Logging is a crucial part of software development that helps us monitor the running state of an application, catch errors, and provide debugging information. In Nuxt 3, the Nuxt Kit
A powerful set of logging tools is provided, allowing you to easily log messages and attach additional features.

1. What is Nuxt Kit logging?

In Nuxt Kit, logging is done through a logger instance. You can use it to log information, warnings, and error messages.Nuxt Kit defaults to using theconsola
As a logging tool, it offers rich features such as color output, different logging levels and formatting options.

2. UtilizationuseLogger

useLogger function (math.)

useLogger is the function to get a logger instance that you can use to get a logger and use it in your code.

function signature

function useLogger(tag?: string): ConsolaInstance

parameters

  • tag: string (Optional)
    • Description: All log messages are prefixed with a label that makes it easy to identify which module or feature the log is from.

return value

  • Returns aConsolaInstanceYou can use it to record log messages.

3. Step-by-step demonstration: How to use logging in Nuxt 3

Next, we'll walk through a sample project that demonstrates how to use logging in Nuxt 3.

3.1 Creating a new Nuxt 3 project

First, install and create a new Nuxt 3 project:

npx nuxi init my-logging-app
cd my-logging-app
npm install

3.2 Create a logging module

In the project root directory, create a file named of the document:

//
import {defineNuxtModule, useLogger} from '@nuxt/kit';

export default defineNuxtModule({
    setup(options, nuxt) {
        const logger = useLogger('my-module');

        ('Module has been initialized!'); // Recording information logs

        // Analog use
        ('render:route', (route) => {
            (`Rendering route: ${}`); // Logging Render Routing Events
        });
    }
});

3.3 Registering modules in the project

exist Register your logging module in the

//
export default defineNuxtConfig({
    modules: [
        '. /' // Introduce your logging module
    ]
}).

3.4 Running the project

Now that your project setup is complete, start the Nuxt 3 Development Server with the following command:

npx nuxi dev

3.5 Viewing Log Output

Open a browser and visit your project (usually thehttp://localhost:3000), you should see log output similar to the following in your terminal:

[INFO] 2023-xx-xxTxx:xx:xx: Module has been initialized!
[INFO] 2023-xx-xxTxx:xx:xx: Rendering route: /

Whenever you render a new route, you will see a new log message.

4. Summary

Using Nuxt Kit's logging functionality in a Nuxt 3 project. We created a simple logging module with theuseLogger
function logs messages in the application. Logging helps you to easily trace the execution of your application and debug issues.
