cypress-env-plugin v1.0.0

Cypress Env Plugin

An unofficial plugin for loading your environment into your Cypress environment, such as dotenv.

Installation

npm

npm i -D cypress-env-plugin

yarn

yarn add -D cypress-env-plugin

Usage

In your cypress/plugins/index.js file:

Basic example

const { createEnvPlugin } = require('cypress-env-plugin');
/**
 * With no prefix a .env of:
 * SECRET_KEY=SECRET_KEY
 * CYPRESS_API_URL=https://api.cool.com/api/
 *
 * Will expose to Cypress Env:
 * API_URL=https://api.cool.com/api/
 */
// Initialise the plugin
const envPlugin = createEnvPlugin({
  env: require('dotenv').config(),
});

module.exports = (on, config) => {
  // Add the plugin
  envPlugin(config);
  return config;
};

Remove prefix restriction example

By default, we filter out any environment variables unless they're prefixed with CYPRESS_, if you want to load everything from your .env you can pass null to the prefix property,

const { createEnvPlugin } = require('cypress-env-plugin');
/**
 * With a null prefix a .env of:
 * SECRET_KEY=SECRET_KEY
 * CYPRESS_API_URL=https://api.cool.com/api/
 *
 * Will expose to Cypress Env:
 * SECRET_KEY=SECRET_KEY
 * CYPRESS_API_URL=https://api.cool.com/api/
 */
// Initialise the plugin
const envPlugin = createEnvPlugin({
  env: require('dotenv').config(),
});

module.exports = (on, config) => {
  // Add the plugin
  envPlugin(config);
  return config;
};

Custom prefix example

You can also provide your own prefix:

const withCustomPrefix = createEnvPlugin({
  prefix: 'WHATEVER_',
  env: require('dotenv').config(),
});

Plain object example

I'm not sure why, but you can also pass a plain object for your environment. process.env maybe?

const withCustomPrefix = createEnvPlugin({
  prefix: 'WHATEVER_',
  env: {
    WHATEVER_API_KEY: '123578123718923',
  },
});
