• Load environment variables from the command line API_BASE=/v1/ rollup
• Load environment variables from .env files
• Expand environment variables API_URL=$API_BASE/users
• Define environment variables for a specific environment (e.g. .env.production)
• Load priorities of .env.* files (e.g. .env.production > .env)
• Hierarchical cascading configuration in monorepo projects (Nx, Turbo, etc.) apps/next-app/.env > apps/.env > .env

Install

npm add @dotenv-run/rollup --save-dev

Usage

Create a rollup.config.js configuration file and import the plugin:

import env from "@dotenv-run/rollup";

export default {
  input: "src/index.js",
  output: {
    file: "dist/index.js",
  },
  plugins: [env({ prefix: "API", verbose: true, root: "../../.." })],
};

Then call rollup either via the CLI or the API.
