# syncthing-hooks
|
|
|
|
Run shell scripts via event hook files (similar to Git hooks) when changes are detected in a [Syncthing](https://syncthing.net/) folder.
|
|
|
|
## Prerequisites
|
|
|
|
[Node.js >= 10](https://nodejs.org/en/)
|
|
|
|
## Installation
|
|
|
|
```sh
|
|
npm i -g syncthing-hooks
|
|
```
|
|
|
|
## Usage
|
|
|
|
You can simply run the watcher process via:
|
|
|
|
```sh
|
|
API_KEY=mykey syncthing-hooks
|
|
```
|
|
|
|
Don't forget to substitute `mykey` with your syncthing API key, which can be found in the settings in the GUI.
|
|
|
|
If Syncthing runs on another host or listens to a non-default port, you can specify an URL by using `ST_URL`.
|
|
Note that this URL has to include the protocol, hostname, port and path, e.g.:
|
|
|
|
```
|
|
ST_URL=http://<ip>:8384/rest/events
|
|
```
|
|
|
|
It won't install itself as a daemon by default, however. In order to run it as a service, it is recommended to install [pm2](https://pm2.keymetrics.io/):
|
|
|
|
```sh
|
|
npm i -g pm2
|
|
```
|
|
|
|
You can then register it as a daemon via:
|
|
|
|
```sh
|
|
pm2 start "API_KEY=mykey syncthing-hooks" --name sthooks
|
|
```
|
|
|
|
To create the daemon automatically on startup, consult [this documentation](https://pm2.keymetrics.io/docs/usage/startup/).
|
|
|
|
You can follow the output of your hooks by using:
|
|
|
|
```sh
|
|
pm2 logs
|
|
```
|
|
|
|
## Hooks
|
|
|
|
Create a folder in your home directory called `.syncthing-hooks`.
|
|
A different directory can be set using `ST_HOOK_ROOT`.
|
|
Each hook is a file with the following naming scheme:
|
|
|
|
`folder-name-delay`
|
|
|
|
The folder name is the 11 character unique string found in the syncthing GUI. The delay is a string (anything parseable by the [ms module](https://github.com/zeit/ms)) indicating the idle time after an event, so that hooks aren't executed multiple times on successive changes in a short interval.
|
|
|
|
An example: a script at the location `~/.syncthing-hooks/night-owlzz-5m` will be executed five minutes after the most recent event in the folder with the identifier `night-owlzz`.
|
|
|
|
Don't forget to `chmod +x` the script.
