The error message "The property 'env' is not present in the 'ImportMeta' type. ts(2339)" indicates that the 'env' property is

After starting a new project with vue.js and vite, I encountered a problem. Everything worked fine when using npm run dev, but I kept getting an error when running npm run build:

Property 'env' does not exist on type 'ImportMeta'.ts(2339)

import { createRouter, createWebHistory } from 'vue-router'
import HomeView from '../views/HomeView.vue'

const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    {
      path: '/',
      name: 'home',
      component: HomeView
    },
    {
      path: '/about',
      name: 'about',
      // route level code-splitting
      // this generates a separate chunk (About.[hash].js) for this route
      // which is lazy-loaded when the route is visited.
      component: () => import('../views/AboutView.vue')
    }
 ]
})

// test access to Vite environment variable
console.log(import.meta.env.BASE_URL);

export default router

Below is my env.d.ts

/// <reference types="vite/client" />
interface ImportMeta {
  readonly env: Record<string, string>;
}

And here is my tsconfig.json

{
  "files": [],
  "references": [
    {
      "path": "./tsconfig.node.json"
    },
    {
      "path": "./tsconfig.app.json"
    },
    {
      "path": "./tsconfig.vitest.json"
    }
  ],
  "compilerOptions": {
    "module": "NodeNext",
    "allowJs": true,
    "types": ["vite/client"]
  }
}

I have already tried adding compiler options for vite/client, but the issue persists. Any tips or guidance would be greatly appreciated. Thank you in advance for any assistance.

Answer №1

When working on my Vite project with version ^4.4.5, I found that adding the following line at the top of the file within vite-env.d.ts was necessary:

/// <reference types="vite/types/importMeta.d.ts" />

As a result, my src/vite-env.d.ts now looks like this:

/// <reference types="vite/client" />
/// <reference types="vite/types/importMeta.d.ts" />

I did not have to update my tsconfig.json file in this case, possibly because of the Vite version (v4) being used for this project.

Answer №2

While working on a project using React.ts with Vite, I encountered a similar issue. Everything was functioning well with `npm run dev`, but when I ran `npm run build`, I kept getting the error message saying "Property 'env' does not exist on type 'ImportMeta'.ts(2339)".

After some extensive research and trial and error, I managed to find a solution that worked for me:

  1. Create a file named `vite-env.d.ts`: In the root directory of your project (where `vite.config.js` or `vite.config.ts` is located), create a file called `vite-env.d.ts`. This file will extend TypeScript's type definitions to include `import.meta.env`.

    Here's the content you need to add:

interface ImportMetaEnv {
  readonly VITE_YOUR_URL: string;
  readonly VITE_REALM: string;
  readonly VITE_CLIENT_ID: string;
 
}

interface ImportMeta {
  readonly env: ImportMetaEnv;
}
  1. Update your `tsconfig.json`: Ensure that your `tsconfig.json` is configured to include the type definitions from the `vite-env.d.ts` file. Here is an example configuration:
{
  "compilerOptions": {
    // Your compiler options here
  },
  "include": ["src", "vite-env.d.ts"]
}
  1. Restart Your Development Server: Changes to environment files or TypeScript configurations sometimes require restarting your development server. Once you've made the necessary changes, stop and restart your development server.

  2. Access Environment Variables in Your Code: You can now safely access environment variables using `import.meta.env` in your code. For example:

const apiUrl = import.meta.env.VITE_YOUR_URL;

By following these steps, I was able to resolve the error and successfully build my project without any further issues. Hopefully, this solution proves helpful to others facing a similar problem!

Answer №3

After following all the provided instructions, I found no solution to my issue. It turned out that the root cause of the error was located in tsconfig.vitest.ts

The resolution required removing a specific line:

"include": ["tests/**/*.ts", "src/**/*.vue", "src/**/*.ts"],

Once that line was removed, the error disappeared!

To identify this fix, I decided to start fresh by creating a new blank project using npm init vue@latest. From there, I carefully compared all configuration files with my own.
