Package Exports

babel-plugin-transform-vite-meta-env

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (babel-plugin-transform-vite-meta-env) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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

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;

Installation

npm install --save-dev babel-plugin-transform-vite-meta-env

Usage

With a configuration file (Recommended)

{
  "plugins": ["babel-plugin-transform-vite-meta-env"]
}

Via CLI

babel --plugins babel-plugin-transform-vite-meta-env script.js

Via Node API

require('@babel/core').transformSync('code', {
  plugins: ['babel-plugin-transform-vite-meta-env']
})
