[SOLVED] Implementing Server-Side Events in appwrite function.

I want implement server side events in appwrite. For implementing server side event I need a server which supports this. In express server I can do this by res.write(). But in appwrite function I can't do this as it supports on res.send and res.json. Is there any way to achieve SSE in appwrite function?

TL;DR

To implement server-side events (SSE) in an Appwrite function, you can follow these steps: 1. Add a variable, like `action`, to the data you send to the function. This allows you to create logical routes within the function based on the `action` value. 2. Keep in mind that Appwrite functions use `micro` server behind the scenes. While you can't develop with a full backend mindset, you can treat the function as a direct endpoint for executing your code. 3. Deploy your functions to your Appwrite instance (self-hosted or cloud) and access them using the available SDKs. 4

You want to be able to send events from an Appwrite function? Or you want your Appwrite function to act as a server?

Can you elaborate more about your use case?

My requirement is my appwrite function generate random numbers for 10 senconds and I want to send these random numbers to all the active users.

I want to send randomly generated numbers in real time.

this appwrite function runs once in an hour

Mmm You can try workaround like so.

Function

Create some Appwrite function.
When trigger make the function generate 10 random numbers.
Insert the numbers into a collection

Realtime

Create Realtime channel
subscribe to the channel of the with the previous collection.

Now you'll have a realtime event that will broadcast to all of the subscriptions with 10 random numbers.

OK. this could be done.

How to achieve Appwrite function to act as a server?

In what way?

That you can access it directly?

Appwrite function runs on which server?

To what part you mean?

Appwrite function are scale-to-zero cloud functions.

If I use nodeJS for writing appwrite fuction, does it use express server or http server

That mean, you can deploy your functions to your Appwrite instance (self-hosted or cloud) Then, access your function using one of the available SDKs.

Got you

It uses micro server, You can find more about it here https://github.com/open-runtimes/open-runtimes/blob/main/runtimes/node-14.5/server.js

Appwrite uses micro behind the scenes. But, this part is hidden from you. So, when developing a service using Appwrite function you can't develop it with a full backend mindset, But, think of it as a direct endpoint in which you're executing your code.

That mean, you can't have routes for your function.

But - it's common - to create logical routes. So you can add a variable to data you're sending to the function, Let say action Then inside the function you can check action value and act according to that value.
