Utilizing localization files to implement language settings based on region

Having a list of countries in three different languages as:

countries-fr.js
countries-en.js
countries-de.js

The goal is to require these files inside the component based on the selected language.

Currently, the approach involves importing all files first:

<template>
...
<p v-for="country in countryList"> {{ country.name }} </p>
...
</template>

<script>
import {EN} from '../../countries-en.js'
import {DE} from '../../countries-de.js'
import {FR} from '../../countries-fr.js'

export default {
  data () {
   EN, FR, DE
  },

  computed:  {
    countryList () {
      let lang = this.$store.state.user.lang

      if(lang == "EN"){return this.EN},
      if(lang == "FR"){return this.FR},
      if(lang == "DE"){return this.DE},
    }
  }
}

Although it works, importing multiple files beforehand can be tedious, especially for many languages.

The question here is: how can I dynamically import a file based on the current locale?

One possible solution could involve adding if/else statements before the <script> section, but that might not be the most efficient way of importing files.

Answer №1

To enhance the performance of your application, consider implementing async and dynamic imports when working with webpack or the standard vue-cli build tool. If you're interested in learning more about this topic, check out the following article: https://medium.com/@michalozogan/how-to-split-moment-js-locales-to-chunks-with-webpack-de9e25caccea

Here is a basic example:

const content = () => import(`../../countries-${locale}.js`)

Alternatively, you can utilize fetch() once the location has been determined if bundling the files is not required. For instance, you can set the locale in a router navigation guard, fetch the content, and make use of it. Keep in mind that the content must be hosted somewhere to allow for fetching, so you may need to upload it yourself or leverage a service like contentful.
