Introduction

  • To add console output for packaging time in a Vue CLI 2 project, you need to modify the configuration files and possibly use custom scripts.

  • One approach is to use the vue-cli-service build command with specific verbosity settings to control the output.

  • You can also modify the vue.config.js file to include custom logging using Webpack plugins.

  • Another method involves editing the package.json file to disable ESLint rules that block console statements.

  • Using the webpack.DefinePlugin, you can define environment variables to log specific information during the build process.

Modifying package.json [1]

  • Locate the package.json file in the root directory of your Vue CLI 2 project.

  • Find the rules section within the eslintConfig object.

  • Change the no-console rule to 0 to allow console statements.

  • Restart your Vue server to apply the changes.

  • This modification will enable console logging during development and build processes.

Using vue.config.js [2]

  • Create or edit the vue.config.js file in the root directory of your project.

  • Use the configureWebpack option to add custom Webpack configurations.

  • Include the webpack.DefinePlugin to define environment variables for logging.

  • Example: const fs = require('fs'); const packageJson = fs.readFileSync('./package.json'); const version = JSON.parse(packageJson).version || 0;

  • This setup allows you to log the version or other details during the build process.

Webpack Plugins [2]

  • Webpack plugins can be used to customize the build process and add logging.

  • The webpack.DefinePlugin allows you to define global constants that can be used in your application.

  • Example: new webpack.DefinePlugin({ 'process.env': { PACKAGE_VERSION: '"' + version + '"' } })

  • This plugin can be configured in the vue.config.js file.

  • Using plugins helps in logging specific details like build time, version, and other environment variables.

ESLint Configuration [1]

  • ESLint rules can block console statements, causing errors during the build process.

  • To allow console logging, modify the eslintConfig section in package.json.

  • Set the no-console rule to 0 to disable this restriction.

  • This change will enable console statements in your Vue components and methods.

  • Restart the development server to apply the new ESLint configuration.

Custom Scripts [3]

  • Custom scripts can be added to the scripts section of package.json.

  • These scripts can include commands to log specific details during the build process.

  • Example: "build": "vue-cli-service build && echo 'Build completed'"

  • Using custom scripts allows for more flexibility in logging and other build-related tasks.

  • Ensure that the scripts are properly tested to avoid build failures.
