@devmy/cypress-dotenv

@devmy/cypress-dotenv is a TypeScript library designed to integrate dotenv configuration with @dotenv-run/core into your Cypress setup, simplifying the management of environment variables for both component and end-to-end (E2E) tests.

• ✅ Load environment variables from .env files
• ✅ Load environment variables from .env.vault 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

Installation

Install the package via npm:

npm install @devmy/cypress-dotenv

or via yarn:

yarn add @devmy/cypress-dotenv

or via pnpm:

pnpm add @devmy/cypress-dotenv

Usage

Dotenv Configuration

The dotenv configuration options in this library use DotenvRunOptions of dotenv-run/core.

defineConfigWithDotenv

The defineConfigWithDotenv function invokes Cypress's defineConfig, loading environment variables from dotenv.

Example:

import { defineConfigWithDotenv } from '@devmy/cypress-dotenv';

export default defineConfigWithDotenv({
   dotenv: {
    prefix: 'FRONTEND_E2E_',
    root: '../../',
  },
  component: {
    specPattern: 'src/**/*.cy.ts',
  },
  e2e: {
    baseUrl: 'http://localhost:3000',
  },
});

dotenvComponentPreset

The dotenvComponentPreset function loads dotenv for component tests in Cypress.

Example:

import { dotenvComponentPreset } from '@devmy/cypress-dotenv';

export default dotenvComponentPreset({
  dotenv: {
    prefix: 'FRONTEND_E2E_',
    root: '../../',
  },
  devServer: {
    framework: 'react',
    bundler: 'webpack',
  },
});

dotenvE2EPreset

The dotenvE2EPreset function loads dotenv for E2E tests in Cypress.

Example:

import { dotenvE2EPreset } from '@devmy/cypress-dotenv';

export default dotenvE2EPreset({
  dotenv: {
    prefix: 'FRONTEND_E2E_',
    root: '../../',
  },
  baseUrl: 'http://localhost:3000',
});
