Can Aedes send webhooks?

[andrewroberts]

I have a Google Apps Script web app that I want to use to receive notifications from Aedes as a HTTP GET or POST request, for then writing into a Google Sheet.

This SO answer suggests the only way to integrate MQTT and Google Sheets with Apps Script is for the broker (Aedes in this case) to generate a webhook.

Is this possible with Aedes?

Aedes doesn't do this out of the box but you can bind to aedes events and call webhooks yourself

Method 1:

You can connect to Aedes through a server-side MQTT client and publish messages to a topic. This way, other MQTT clients, whether they are in a browser or using Node.js, can receive the messages.

Method 2:

You can use HTTP methods like fetch or axios to make requests in Aedes, as described in the documentation here: https://github.com/moscajs/aedes/blob/main/docs/Aedes.md#handler-published-packet-client-callback. Alternatively, you can also use an MQTT client to publish any desired content with 'published callback', similar to Method 1.
