How do I allow Cors in Firebase?

exampleFunction = functions. https. onRequest((request, response) => { cors(request, response, () => {}); return response. send(“Hello from Firebase!”); });4 Nis 2017

The Cloud Functions for Firebase client SDKs let you call functions directly from a Firebase app. To call a function from your app in this way, write and deploy an HTTPS Callable function in Cloud Functions, and then add client logic to call the function from your app .

Requests on your Firebase Hosting site can be proxied to specific HTTP functions . This also allows you to use your own custom domain with an HTTP function.

You can invoke Cloud Functions with an HTTP request using the POST , PUT , GET , DELETE , and OPTIONS HTTP methods. To create an HTTP endpoint for your function, specify –trigger-http as the trigger type when deploying your function .
