Effects of incorporating unnecessary packages on Vue.js performance

In my Vue.js component, I have imported the module useI18n from "vue-i18n" but have not utilized it anywhere within the component. Concerned about how this could affect performance, particularly in terms of bundle size and load times.

  • Will importing a module that goes unused within a component impact its performance?
  • How does this unused import contribute to the overall bundle size and potentially affect the initial loading time of the application?
  • What are the recommended best practices for dealing with unused imports in Vue.js to optimize performance?

I am deliberating on the consequences of including the useI18n module from "vue-i18n" without utilizing it in my Vue.js component, yet remain uncertain about the specific performance ramifications.

Answer №1

I concur with the statement made by Peter Krebs.

Personally, whether I am using vue-cli or vite to generate the bundle, I always refer to the generated report using the following methods:

vue-cli

In the package.json file, when specifying the target for creating the component bundle (referred as lib in this example), include the --report flag: this will produce a report.html file which can help in analyzing the content of the bundle (details available here).

...
"scripts": {
  "lib": "vue-cli-service build --target lib --name mycomponent ./src/index.js --report",
}
...

vite

Install the rollup-plugin-visualizer npm package

In the vite.config.js file, import the plugin, add it to the plugins field in the returned configuration, and view the results by opening the file specified in the filename field.

import { visualizer } from 'rollup-plugin-visualizer'

const plugins = [visualizer({
    filename: 'dist/report.html'
})]
