Calling a Cloud Function

This feature allows you to call a Cloud Function named 'sayHello' from your client-side application. The function takes an object as an argument, in this case, { name: 'Firebase' }, and returns a promise that resolves with the result of the function call.

const functions = require('@firebase/functions');

const sayHello = functions.httpsCallable('sayHello');
sayHello({ name: 'Firebase' }).then(result => {
  console.log(result.data);
});

Handling Errors

This demonstrates how to handle errors when calling a Cloud Function. The error object contains details about what went wrong, which can be used for debugging or displaying an appropriate message to the user.

sayHello({ name: 'Firebase' }).catch(error => {
  const code = error.code;
  const message = error.message;
  const details = error.details;
  // Handle the error
});
