Envlet for Node.js

One line at boot and process.env is full. Node, Bun, and edge runtimes.

Inject

import { inject } from "@envlet/sdk";

await inject();

const stripe = new Stripe(process.env.STRIPE_KEY);

Load

import { load } from "@envlet/sdk";

const values = await load();

const db = connect(values.DATABASE_URL);

Get

import { get } from "@envlet/sdk";

const stripeKey = await get("STRIPE_KEY");

Install

npm install @envlet/sdk

Set up

01
Install
npm install @envlet/sdk.
02
Set one secret
ENVLET_TOKEN on the host. It is the only secret the host keeps.
03
Inject at boot
Call inject() before anything reads process.env.

Will my app start if Envlet is down?: No, and that is the point. The SDK retries for a few seconds, then fails so you notice. It never starts your app with half an environment.
What does the host need?: One variable, ENVLET_TOKEN. Everything else arrives at boot.
Can I still set some values on the Node.js host?: Yes. A value the host already set wins. Pass override if you want Envlet to win instead.

One command. The right values for whoever runs it.
