The `process` variable is not recognized in a Vue/TypeScript component

I've encountered an issue trying to use .env variables in my Vue app. When I ran npm install process, the only syntax that didn't result in an error when importing was:

import * as process from 'process';

Prior to this, I received the following error message:

Cannot find name 'process'. Do you need to install type definitions for node? Try `npm i --save-dev @types/node`. 

After running the suggested installation and adding "node" to types in my tsconfig file, I defined a member variable like so:

const testVar = process.env.TEST_VAR

I attempted both TEST_VAR=just test and TEST_VAR="just test" in my .env file. The .env file is located in the root folder of the project, outside the src folder.

Despite all these efforts, the variable keeps returning as undefined.

mounted(){
 console.log('ENV TEST -> ', this.testVar)
 alert(`ENV2 : ${this.testVar}`)
 ...
}

If anyone could offer assistance with resolving this issue, it would be greatly appreciated. Thank you!

Answer №1

Only variables that are prefixed with VUE_APP_ will be included in the client bundle at compile time. Check out Vue's documentation

These variables can then be accessed within components.

mounted() {
 console.log(process.env.VUE_APP_TEST_VAR)
}
