एक्सप्रेस का उपयोग करते हुए इस पर एक अच्छा आधिकारिक उदाहरण है - भविष्य में उपयोगी हो सकता है: https://github.com/firebase/functions-samples/blob/master/authorized-https-endpoint/functions/index.js (बस नीचे चिपकाए गए) पक्का)
ध्यान रखें कि स्लग के exports.appतहत आपके कार्य उपलब्ध हैं /app(इस मामले में केवल एक फ़ंक्शन है और इसके तहत उपलब्ध है <you-firebase-app>/app/hello। इससे छुटकारा पाने के लिए आपको वास्तव में एक्सप्रेस भाग को थोड़ा फिर से लिखना होगा (सत्यापन के लिए मिडलवेयर हिस्सा वही रहता है - यह बहुत काम करता है) अच्छा है और टिप्पणियों के लिए काफी समझ में आता है)।
