env-restorer

Utility that snapshots the environment variables from process.env and can restore them on demand. Initially developed for testing vandium.

Features

  • Automatically snapshots environment variable state
  • Nested snapshots are allowed
  • No dependencies

Installation

Install via npm.

npm install env-restorer

Getting Started

A snapshot of the environment variables is created automatically when the library is loaded.

const envRestorer = require( 'env-restorer' );
 
// change environment variables
process.env.MY_SPECIAL_VALUE = '42';
 
envRestorer.restore();
// restore environment variables back to initial state (MY_SPECIAL_VALUE will no longer exist)

To create another snapshot of the environment variables state, simply call snapshot():

const envRestorer = require( 'env-restorer' );
 
// change environment variables
process.env.MY_SPECIAL_VALUE = '42';
 
const snapshot = envRestorer.snapshot();
 
// change environment variables
process.env.MY_SPECIAL_VALUE = '43';
 
snapshot.restore();
// process.env.MY_SPECIAL_VALUE will now equal '42'
 
envRestorer.restore();
// restore environment variables back to initial state (MY_SPECIAL_VALUE will no longer exist)
