Little help needed : I want to send push notification in mobile apps from react website

I want to send push notification in mobile apps from react website, i am not using server side code so can you tell me how will i send push notification directly from react and appwrite function ? i am using one signal for sending push notification

It seems like OneSignal has a good Node SDK

You can then create a Node cloud-function. Within it add the One Signal Package
Then the rest is like a regular JavaScript code.

Then you can use the client SDK to execute the function from the device.

You can also use many more SDKs of OneSignal that has function runtime within Appwrite.

but when i upload node js function in appwrite function , it does not submit

they asked for .gz file

Use Appwrite cli to create and deploy the function
