Envobj

Tiny environment variable helper.

Ensures that all the required variables are present. Throws on invalid and missing values.

Install

npm install envobj

Usage

const { envobj, string, number, boolean } = require("envobj");
 
const env = envobj(
  {
    DATABASE_URL: string,
    PORT: number,
    USE_PAPERTRAIL: boolean
  },
  process.env,
  {
    PORT: "8000" // Requires a number, set `8000` if `PORT` is missing.
  }
);

Built-in validators: string, number, boolean and integer.

.env

Use with localenv to populate process.env automatically in development from .env and .env.local.

import { envobj, number } from "envobj";
 
import "localenv";
 
export const env = envobj(
  {
    PORT: number
  },
  process.env
);

Tip: Check in .env and exclude .env.local so teammates can get started quickly.
