Environment variables

Functions read configuration from process.env (JavaScript/TypeScript) or os.environ (Python). You can set variables per-environment from the CLI or the dashboard.

Setting a variable

CLI

nimbus env set STRIPE_KEY sk_live_••••••••• --env production

Dashboard

Go to Project → Settings → Environment Variables, choose an environment, and add a key/value pair.

Reading it in a function

functions/charge.ts

export default function handler(request: Request) {
  const key = process.env.STRIPE_KEY;
  // ...
}

Danger

Variables set without --secret are visible to anyone with access to the project dashboard. Use --secret for API keys and credentials:

nimbus env set STRIPE_KEY sk_live_••••••••• --secret --env production

Environments

Nimbus has three built-in environments, each with its own variable set:

Environment	Triggered by
preview	nimbus dev
staging	nimbus deploy --env staging
production	nimbus deploy --env production
