how do I set cors headers with node js in my cloud functions
TL;DR
To set CORS headers in your Node.js cloud functions, add the headers using res.set() in your function code. Make sure the headers are set before sending the response.
Example:
```javascript
res.set({
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Methods': 'GET, POST',
'Access-Control-Allow-Headers': 'Content-Type, Authorization'
});
```
Ensure the headers are set correctly and the response is sent after setting them. This should allow access from other domains.
