babel-plugin-transform-vite-meta-env




> Please note: this plugin is intended to provide an approximation of some of Vite specific
> transformations when running the code in non-Vite environment, for example, running tests with a
> NodeJS based test runner.
>
> The functionality within these transformations should not be relied upon in production.

Example

In

``
const mode = import.meta.env.MODE;
const baseUrl = import.meta.env.BASE_URL;
const nodeEnv = import.meta.env.NODE_ENV;
const dev = import.meta.env.DEV;
const prod = import.meta.env.PROD;
const viteVar = import.meta.env.VITE_VAR;
const other = import.meta.env.OTHER;
`

Out

`
const mode = process.env.MODE;
const baseUrl = '/';
const nodeEnv = process.env.NODE_ENV || 'test';
const dev = process.env.NODE_ENV !== 'production';
const prod = process.env.NODE_ENV === 'production';
const viteVar = process.env.env.VITE_VAR;
const other = undefined;
