ts-tinyenv

Make using process.env in typescript super simple. (See here for motivation.)

The package has one function, which is only 5 lines of code so easily audited.

The function (env) takes the name of a process.env environment variable and returns it as a string. If the env var is missing, an Error is thrown.

It lets you write simple TS code like this:

let currentEnvironment: string;
currentEnvironment = env('NODE_ENV');

Install

npm install ts-tinyenv

Usage

import { env } from 'ts-tinyenv';

const aString = env('SOME_ENV_VAR'); // return type is always string

console.log('SOME_ENV_VAR is: ', aString);

If process.env.SOME_ENV_VAR is not set, an Error will be thrown with message like:

Missing: process.env['SOME_ENV_VAR'].

Tips

You can use something like dotenv-safe to ensure your service fails fast if you are missing any env variables, and if you use that corretly then you should never actually see errors thrown by this function.

Advanced Environment Variable Support

This package is intentionally super minimal. You get a string, or an error.

For more advanced usage, see packages like:

• env-var
• getenv
• envalid

and of course:

• dotenv
• dotenv-safe
