Set it in env

snippets-node/firestore/main/index.js

Lines 36 to 44 in 8985ddb

	const serviceAccount = require('./path/to/serviceAccountKey.json');
	admin.initializeApp({
	credential: admin.credential.cert(serviceAccount)
	});
	const db = admin.firestore();

How can I set it in .env or system environment?
e.g.

 admin.initializeApp({ 
   credential: admin.credential.cert(process.env.SERVICE_ACCOUNT_KEY) 
 });
