# SpaceAPI Daemon

`spaceapid` serves a [SpaceAPI](https://spaceapi.io)-compatible JSON on port 8080:

```shell
$ curl -X GET http://[::1]:8080 | jq
{
  "api_compatibility": [
    "14"
  ],
  "space": "CCCHH",
  ...
}

```

## Configuring

spaceapid has to be configured via one or multiple json files.
A sample configuration is provided as [config-template.json](./config-template.json).
The config consists of three parts:

- `"credentials"`
	- List of Username/Password credentials for HTTP BasicAuth
- `"dynamic"`
	- The configuration for the dynamic parts of the message
- `"response"`
	- The static (pre-filled) parts of the response

See [Running](#running) for details.

## Updating values

The state of the boolean `state->open` property can be modified via `/state/open`:

```shell
curl -X PUT -u user:password -d true http://[::1]:8080/state/open
```

The same is true for the endpoints for sensors configured under `"dynamic"`.
Currently only `temperature` and `humidity` are implemented.

```shell
curl -X PUT -u user:password -d 23.42 http://[::1]:8080/{temperature,humidity}/location[/name]
```

## Building

See the `go.mod` file for minimum required Go version.
There are currently no dependencies apart from the Go standard library.

## Running

Set the environment variable to a comma-separated list of config files or pass the `-c` flag.

```shell
env CONFIG_PATH=config-template.json go run .
# OR
go run . -c credentials.json,dynamic.json,response.json
```
