# Signal K Resources Provider Plugin:

__Signal K server plugin that implements the Resource Provider API__.

_Note: This plugin requires Signal K Server v2.0 or later!_

---

This plugin is a resource provider, facilitating the storage and retrieval of the following resource types defined by the Signal K specification:
- `resources/routes`
- `resources/waypoints`
- `resources/notes`
- `resources/regions`   

as well as providing the capability to serve custom resource types provisioned as additional paths under `/signalk/v2/api/resources`.

- _example:_ `/signalk/v2/api/resources/fishingZones`   

Each path is provisioned with `GET`, `PUT`, `POST` and `DELETE` operations enabled.

Operation of all paths is as set out in the OpenAPI resources definition available in the Signal K server Admin console.


---

## Data Storage:

Resources are stored in the server's filesystem under the path `~/.signalk/plugin-config-data/resources-provider/resources`.

A separate file is created for each resource with a name that reflects the resources `id`.

Each resource is created within a folder allocated to that specific resource type. 

_Example:_
```
~/.signalk
    /resources
        /routes
            ...
        /waypoints
            ...
        /notes
            ...
        /regions
            ...
        /charts
            ...
        /my_custom_type
            ...
```


---
## Use and Operation:

Once configured, the plugin registers itself as the resource provider for each of the enabled resource types and the Signal K server will pass all _HTTP GET, POST, PUT and DELETE_ requests to the plugin.
