@postnord/pretty-env

Introduction

This module gives you a nice interface to handle environment variables.

Quick start

import envService from '@postnord/pretty-env'

// in batch
const { API_BASE_URL, NODE_URL } = envService.requireEnvs({ envs: ['API_BASE_URL', 'NODE_URL'] }) // returned envs are typed as string, so no more process.env.NODE_URL as string

// single env var fetch
const myEnv = envService.requireSingleEnv({ env: 'mySingleEnv' })

// When the env does not exist
envService.requireSingleEnv({ env: 'myNonExistingEnv' }) // throws "Environment variable myNonExistingEnv is missing"

// If you want to parse and validate the value
envService.requireSingleEnv<Array<string>>({
  env,
  parser: JSON.parse,
  validateValue: {
    validationFunction: Array.isArray,
    errorMessage: 'Should be an array but is not',
  }
})
