Optimizing the build of the production environment is an important step in the development process.nuxi analyze command provides a tool that can help you analyze the size and structure of production packages to identify potential performance bottlenecks and optimization points.
What is it?nuxi analyze？
nuxi analyze command to build and analyze a production package for a Nuxt application. This is an experimental feature that helps you understand the size of production packages and identify large dependencies and optimization points. By analyzing the production package, you can make targeted optimizations to improve the loading speed and performance of your application.
basic usage
npx nuxi analyze [--log-level] [rootDir]
Parameter description
-
rootDir: Directory of the target application, defaults to the current directory (
.). If your Nuxt application is not in the current directory, you can specify another path. - --log-level: Set the logging level to control the level of detail output during analysis.
How to usenuxi analyze command
Here's how to usenuxi analyze command to analyze the steps of your Nuxt application:
1. Make sure you have Nuxt installed.
First, make sure you have installed , and that the project has been created and configured. If you haven't created a project yet, you can create a new Nuxt project using the following command:
npx nuxi@latest init my-nuxt-app
cd my-nuxt-app
2. Preparing the analytical environment
runningnuxi analyze Before the command, make sure that your application can be built properly in production mode. You can build your application with the following command:
npm run build
This command will generate a build file for the production environment, usually located in the.nuxt Catalog.
3. Operationnuxi analyze command
In your project directory, run the following command to analyze the production package:
npx nuxi analyze
This will build the Nuxt application and analyze the resulting production package. The results of the analysis will be displayed in the terminal, including the sizes of the individual modules and possible optimization recommendations.
4. Reading the results of the analysis
The results of the analysis will include information on the following areas:
- Package size: Size information for each module to help you identify which module is taking up the most space.
- dependency graph: Shows the dependencies between modules to help you understand how modules are interconnected.
- Optimization Recommendations: The tool provides optimization suggestions, if any, such as reducing package size, removing unused dependencies, and so on.
typical example
Let's say you've created a file namedmy-nuxt-app in the project directory and run thenuxi analyze command. The following is a sample output:
npx nuxi analyze
> Building Nuxt application for production...
> Analyzing production bundle...
📦 Production bundle size:
- .nuxt/dist/server/ (123MB)
- .nuxt/dist/client/ (45MB)
🔍 Analyzing modules...
- vue (15MB)
- axios (10MB)
- lodash (8MB)
- other (90MB)
📉 Optimization suggestions:
- Consider using dynamic imports to split code
- Remove unused lodash methods
In this example, the output shows the overall size of the production package and lists the main modules and their sizes. Some optimization suggestions are also provided, such as using dynamic imports to split the code to reduce the size of the package.
summarize
Using the nuxi analyze command helps you gain insight into the structure and size of production packages so that you can make targeted optimizations. By analyzing production packages on a regular basis, you can identify and resolve performance bottlenecks and improve application loading speed and user experience.
