What leads to the inability to utilize environment variables in this TypeScript app built with Vue 3?

Currently, I am developing a single page application utilizing Vue 3 and TypeScript. The main purpose of this app is to interact with an API. All the necessary information including the API's URL and key are stored in the 'src\env.js' file:

export default {
 api_url: "https://api.themoviedb.org/3/movie/550?",
 api_key: "somerandomkey"
}

Within the 'src\views\HomeView.vue' file, my code structure looks like this:

<template>
<div class="container">
    <h1 class="page-title">{{ pageTitle }}</h1>
    <MoviesList />
</div>
</template>

<script lang="ts">
import { defineComponent } from 'vue';
import axios from 'axios';
import env from '@/env.js'
import MoviesList from '../components/MoviesList.vue';

export default defineComponent({
    name: 'HomeView',

    components: {
      MoviesList
    },

    data() {
      return {
        pageTitle: "Popular Movies",
        movies: [],
      }
    },
    methods: {
      getMovies() {
        axios.get(`${env.api_url}api_key=${env.api_key}`).then(response => {
        this.movies = response.data.results;
        })
        console.log(this.movies)
      }
    }
});
</script>

An Issue Arises

Upon compilation, an error message is displayed in the terminal:

Could not find a declaration file for module '@/env.js'.

Seeking Clarifications

  1. What could be causing this complication?
  2. How can this issue be effectively resolved?

Answer №1

It seems that the use of the @ symbol signifies the src folder to your builder and the file is located there.

The error being displayed is due to TypeScript not recognizing the types when you import a .js file.

I suggest two possible solutions:

  • Rename src/env.js to src/env.ts - this will make it a TypeScript file, allowing TS to automatically infer the types
  • If renaming the file is not an option, create a declaration file (env.d.ts) where you manually define the types for the module exports:
export default {
  api_url: string,
  api_key: string
}
