Loading Environment Variables

Node.js (dotenv)

import dotenv from 'dotenv';

// Load .env file
dotenv.config();

// Load specific file
dotenv.config({ path: '.env.production' });

// Access variables
const apiKey = process.env.CLAW_API_KEY;

Docker

# In Dockerfile
ENV NODE_ENV=production

# Or in docker-compose.yml
environment:
  - CLAW_API_KEY=${CLAW_API_KEY}
  - NODE_ENV=production

Kubernetes

# ConfigMap
apiVersion: v1
kind: ConfigMap
metadata:
  name: clawlayer-config
data:
  NODE_ENV: "production"
  PORT: "3000"

# Secret
apiVersion: v1
kind: Secret
metadata:
  name: clawlayer-secrets
type: Opaque
data:
  CLAW_API_KEY: base64encodedvalue

Security Best Practices

1. Never commit .env files - Add to .gitignore

2. Use different keys per environment - Dev, staging, production

3. Rotate keys regularly - Every 90 days minimum

4. Limit key permissions - Use least privilege principle

5. Monitor key usage - Track and alert on unusual activity

6. Use secret management - AWS Secrets Manager, HashiCorp Vault

7. Encrypt sensitive values - In production environments

Validation

Validate environment variables on startup:

import { z } from 'zod';

const envSchema = z.object({
  CLAW_API_KEY: z.string().min(1),
  PORT: z.string().transform(Number).pipe(z.number().int().positive()),
  NODE_ENV: z.enum(['development', 'production', 'test']),
  DATABASE_URL: z.string().url(),
});

const env = envSchema.parse(process.env);

Troubleshooting

Variable Not Found

# Check if variable is set
echo $CLAWLAYER_API_KEY

# Check .env file is loaded
node -e "require('dotenv').config(); console.log(process.env.CLAW_API_KEY)"

Wrong Value

# Check for trailing spaces
cat .env | grep CLAW_API_KEY | od -c

# Check for quotes
# Wrong: CLAW_API_KEY="value"
# Right: CLAW_API_KEY=value
