A utility for executing code under a specific NODE_ENV.

Example Usage

In this example, we are testing some code using Jest. Note that, while Jest is not required to use @shopify/with-env, it is our recommended testing framework for node and javascript applications.

import withEnv from '@shopify/with-env';

it('does one thing in development', () => {
  withEnv('development', () => {
    // your code here
  });
});

it('does another thing in production', () => {
  withEnv('production', () => {
    // your code here
  });
});

It also allows to change (and reset) multiple environment variables at once.

import withEnv from '@shopify/with-env';

it('does one thing', () => {
  withEnv({MY_ENV_ONE: 'test', ANOTHER_ENV: 'test-2'}, () => {
    // your code here
  });
});
