ntfy is a super simple pub-sub notification service. It allows you to send desktop and (soon) phone notifications
|
|
|
|
|
via scripts. I run a free version of it on *[ntfy.sh](https://ntfy.sh)*. No signups or cost.

You can subscribe to a topic either in a web UI, or in your own app by subscribing to an SSE/EventSource
|
|
|
|
|
or JSON feed.
|
|
|
|
|
|
|
|
|
|
Here's how to do it via curl see the SSE stream in `curl`:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
curl -s localhost:9997/mytopic/sse
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
You can easily script it to execute any command when a message arrives:
|
|
|
|
|
```
|
|
|
|
|
while read json; do
|
|
|
|
|
msg="$(echo "$json" | jq -r .message)"
|
|
|
|
|
notify-send "$msg"
|
|
|
|
|
done < <(stdbuf -i0 -o0 curl -s localhost:9997/mytopic/json)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
