Jest unit tests are failing due to an error stating that VUE_APP_CONFIG is not defined

export interface VueAppSettings {
    BASE_URL: string;
    BASE_URL_V2: string;
}

declare const VUE_APP_SETTINGS: VueAppSettings;

export const APP_SETTINGS = { ...VUE_APP_SETTINGS } as const;

I am encountering a reference error in the code snippet above.

Answer №1

Declare is used to inform the compiler that a variable already exists somewhere in the code. It does not actually create the variable.

If your goal is to create a new variable, do not include the declare keyword.

The name (VUE_APP_CONFIG) suggests that you are attempting to access an environment variable, typically defined with the VUE_APP_ prefix to make it available in the production build. To access such a variable, be sure to use process.env:

const VUE_APP_CONFIG = JSON.parse(process.env.VUE_APP_CONFIG) as VueAppConfig

Answer №2

The issue was that Jest was not recognizing this specific value for some reason. However, I managed to resolve it by making an update to jest.config.js and adding the following:

globals: {
    VUE_APP_CONFIG: true,
},

After making this change, everything began to function properly.
