The 'locale' parameter is inherently assigned the type of 'any' in this context

I have been using i18n to translate a Vue3 project with TypeScript, and I am stuck on getting the change locale button to work. Whenever I try, it returns an error regarding the question title. Does anyone have any insights on how to resolve this issue? Below is my code snippet:

<template>
   <div> 
       <span @click="changeLocale('pt-br')" class="flag-icon flag-icon-br m-2"></span>
       <span @click="changeLocale('en-uw')" class="flag-icon flag-icon-us m-2"></span>
       <span @click="changeLocale('es-es')" class="flag-icon flag-icon-es m-2"></span>
   </div>
</template>

<script setup lang = "ts">

export default {
   methods: {
       changeLocale(locale){
           this.$root.$i18n.locale = locale;
       }
   }
}
</script>

<style scoped>

.m-2{
   margin: 2px;
} 

</style>

Answer №1

It seems like the error is related to type checking on the function since no specific line is mentioned for this issue. Your TSConfig is configured to disallow implicit any, but the type parameter for `locale` has not been declared.

To rectify this, you should modify the code as follows:

changeLocale(locale: string){
    this.$root.$i18n.locale = locale;
}

Additionally, it's important to note that you are using the pure setup composition API, so there is no need for exporting default {...}.

You can refactor the code as shown below:

<script setup lang="ts">
const changeLocale = (locale: string) => {
    this.$root.$i18n.locale = locale;
}
</script>
