## Usage ## **[Documentation](https://ntfy.sh/docs/)**
### Publishing messages [Getting started](https://ntfy.sh/docs/) |
[Android/iOS](https://ntfy.sh/docs/subscribe/phone/) |
Publishing messages can be done via PUT or POST using. Topics are created on the fly by subscribing or publishing to them. [API](https://ntfy.sh/docs/publish/) |
Because there is no sign-up, **the topic is essentially a password**, so pick something that's not easily guessable. [Install / Self-hosting](https://ntfy.sh/docs/install/) |
[Building](https://ntfy.sh/docs/develop/)
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.
## Installation
Please check out the [releases page](https://github.com/binwiederhier/ntfy/releases) for binaries and
deb/rpm packages.
1. Install ntfy using one of the methods described below
2. Then (optionally) edit `/etc/ntfy/config.yml`
3. Then just run it with `ntfy` (or `systemctl start ntfy` when using the deb/rpm).
### Binaries and packages
**Debian/Ubuntu** (*from a repository*)**:**
```bash
curl -sSL https://archive.heckel.io/apt/pubkey.txt | sudo apt-key add -
sudo apt install apt-transport-https
sudo sh -c "echo 'deb [arch=amd64] https://archive.heckel.io/apt debian main' > /etc/apt/sources.list.d/archive.heckel.io.list"
sudo apt update
sudo apt install ntfy
```
**Debian/Ubuntu** (*manual install*)**:**
```bash
wget https://github.com/binwiederhier/ntfy/releases/download/v1.5.0/ntfy_1.5.0_amd64.deb
dpkg -i ntfy_1.5.0_amd64.deb
```
**Fedora/RHEL/CentOS:**
```bash
rpm -ivh https://github.com/binwiederhier/ntfy/releases/download/v1.5.0/ntfy_1.5.0_amd64.rpm
```
**Docker:**
Without cache:
```
docker run -p 80:80 -it binwiederhier/ntfy
```
With cache:
```bash
docker run \
-v /var/cache/ntfy:/var/cache/ntfy \
-p 80:80 \
-it \
binwiederhier/ntfy \
--cache-file /var/cache/ntfy/cache.db
```
**Go:**
```bash
go get -u heckel.io/ntfy
```
**Manual install:**
```bash
# x86_64/amd64
wget https://github.com/binwiederhier/ntfy/releases/download/v1.5.0/ntfy_1.5.0_linux_x86_64.tar.gz
# armv7
wget https://github.com/binwiederhier/ntfy/releases/download/v1.5.0/ntfy_1.5.0_linux_armv7.tar.gz
# arm64/v8
wget https://github.com/binwiederhier/ntfy/releases/download/v1.5.0/ntfy_1.5.0_linux_arm64.tar.gz
# Extract and run
sudo tar -C /usr/bin -zxf ntfy_*.tar.gz ntfy
./ntfy
```
## 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`.
