|
**ntfy** (pronounce: *notify*) is a simple HTTP-based [pub-sub](https://en.wikipedia.org/wiki/Publish%E2%80%93subscribe_pattern) notification service.
|
|
It allows you to **send notifications to your phone or desktop via scripts** from any computer, entirely **without signup or cost**.
|
|
It's also open source (as you can plainly see) if you want to run your own.
|
|
|
|
I run a free version of it at **[ntfy.sh](https://ntfy.sh)**, and there's an [open source](https://github.com/binwiederhier/ntfy-android) [Android app](https://play.google.com/store/apps/details?id=io.heckel.ntfy)
|
|
too.

## Usage
|
|
|
|
### Publishing messages
|
|
|
|
Publishing messages can be done via PUT or POST using. Topics are created on the fly by subscribing or publishing to them.
|
|
Because there is no sign-up, **the topic is essentially a password**, so pick something that's not easily guessable.
|
|
|
|
Here's an example showing how to publish a message using `curl`:
|
|
|
|
```
|
|
curl -d "long process is done" ntfy.sh/mytopic
|
|
```
|
|
|
|
Here's an example in JS with `fetch()` (see [full example](examples)):
|
|
|
|
```
|
|
fetch('https://ntfy.sh/mytopic', {
|
|
method: 'POST', // PUT works too
|
|
body: 'Hello from the other side.'
|
|
})
|
|
```
|
|
|
|
### Subscribe to a topic
|
|
You can create and subscribe to a topic either in this web UI, or in your own app by subscribing to an
|
|
[EventSource](https://developer.mozilla.org/en-US/docs/Web/API/EventSource), a JSON feed, or raw feed.
|
|
|
|
#### Subscribe via web
|
|
If you subscribe to a topic via this web UI in the field below, messages published to any subscribed topic
|
|
will show up as **desktop notification**.
|
|
|
|
You can try this easily on **[ntfy.sh](https://ntfy.sh)**.
|
|
|
|
#### Subscribe via phone
|
|
You can use the [Ntfy Android App](https://play.google.com/store/apps/details?id=io.heckel.ntfy) to receive
|
|
notifications directly on your phone. Just like the server, this app is also [open source](https://github.com/binwiederhier/ntfy-android).
|
|
|
|
#### Subscribe via your app, or via the CLI
|
|
Using [EventSource](https://developer.mozilla.org/en-US/docs/Web/API/EventSource) in JS, you can consume
|
|
notifications like this (see [full example](examples)):
|
|
|
|
```javascript
|
|
const eventSource = new EventSource('https://ntfy.sh/mytopic/sse');<br/>
|
|
eventSource.onmessage = (e) => {<br/>
|
|
// Do something with e.data<br/>
|
|
};
|
|
```
|
|
|
|
You can also use the same `/sse` endpoint via `curl` or any other HTTP library:
|
|
|
|
```
|
|
$ curl -s ntfy.sh/mytopic/sse
|
|
event: open
|
|
data: {"id":"weSj9RtNkj","time":1635528898,"event":"open","topic":"mytopic"}
|
|
|
|
data: {"id":"p0M5y6gcCY","time":1635528909,"event":"message","topic":"mytopic","message":"Hi!"}
|
|
|
|
event: keepalive
|
|
data: {"id":"VNxNIg5fpt","time":1635528928,"event":"keepalive","topic":"test"}
|
|
```
|
|
|
|
To consume JSON instead, use the `/json` endpoint, which prints one message per line:
|
|
|
|
```
|
|
$ curl -s ntfy.sh/mytopic/json
|
|
{"id":"SLiKI64DOt","time":1635528757,"event":"open","topic":"mytopic"}
|
|
{"id":"hwQ2YpKdmg","time":1635528741,"event":"message","topic":"mytopic","message":"Hi!"}
|
|
{"id":"DGUDShMCsc","time":1635528787,"event":"keepalive","topic":"mytopic"}
|
|
```
|
|
|
|
Or use the `/raw` endpoint if you need something super simple (empty lines are keepalive messages):
|
|
|
|
```
|
|
$ curl -s ntfy.sh/mytopic/raw
|
|
|
|
This is a notification
|
|
```
|
|
|
|
#### Message buffering and polling
|
|
Messages are buffered in memory for a few hours to account for network interruptions of subscribers.
|
|
You can read back what you missed by using the `since=...` query parameter. It takes either a
|
|
duration (e.g. `10m` or `30s`) or a Unix timestamp (e.g. `1635528757`):
|
|
|
|
```
|
|
$ curl -s "ntfy.sh/mytopic/json?since=10m"
|
|
# Same output as above, but includes messages from up to 10 minutes ago
|
|
```
|
|
|
|
You can also just poll for messages if you don't like the long-standing connection using the `poll=1`
|
|
query parameter. The connection will end after all available messages have been read. This parameter has to be
|
|
combined with `since=`.
|
|
|
|
```
|
|
$ curl -s "ntfy.sh/mytopic/json?poll=1&since=10m"
|
|
# Returns messages from up to 10 minutes ago and ends the connection
|
|
```
|
|
|
|
## Examples
|
|
There are a few usage examples in the [examples](examples) directory. I'm sure there are tons of other ways to use it.

## Building
|
|
Building `ntfy` is simple. Here's how you do it:
|
|
|
|
```
|
|
make build-simple
|
|
# Builds to dist/ntfy_linux_amd64/ntfy
|
|
```
|
|
|
|
To build releases, I use [GoReleaser](https://goreleaser.com/). If you have that installed, you can run `make build` or
|
|
`make build-snapshot`.
