url-env

Select an environment by url

Install

npm install url-env

Usage

Make sure you include polyfills for Object.prototype.entries and String.prototype.startsWith if you need this to work with older browsers. We recommend https://polyfill.io but if you are using a framework then it may already have this covered for you.

Codesandbox example

const { fromObject } = require('url-env');

const availableEvironments = {
  'https://localhost:9300': 'local',
  'https://dev.mydomain.com': 'dev',
  'https://test.mydomain.com': 'test',
  'https://mydomain.com': 'prod'
};

const {pair, url, env} = fromObject(availableEvironments);

// When window.location.href starts with https://dev.mydomain.com
console.log(pair); // ['https://dev.mydomain.com', 'dev']
console.log(env); // https://dev.mydomain.com
console.log(url); // dev

Using strings other than window.location.href (useful when mocking)

const {pair, url, env} = urlEnv.fromObject(availableEvironments, 'http://mymockurl');
