# Simple SpaceAPI
A lightweight [SpaceAPI](https://spaceapi.io/) server
with both web and REST interfaces.
Built with Node.js and [Strapi](https://github.com/strapi/strapi).
![Screenshot](/docs/images/screenshot-main.png?raw=true)
## Quick Start
Install dependencies and start the server in development mode:
```sh
npm install
npm run develop
```
Most files are autogenerated.<br>
The main entry point is `./src/api/spaceapi/controllers/spaceapi.ts`.
## Usage
All endpoint data can be added or modified
via the [admin panel](http://localhost:1337/admin)
or through the REST API.
To list all available API endpoints,
use the [Strapi CLI](https://docs.strapi.io/cms/cli):
```sh
npm run strapi routes:list
```
### API Tokens
To update data, you need an API token.<br>
Tokens can be generated and managed in the admin panel, under
[Settings → API Tokens](http://localhost:1337/admin/settings/api-tokens).<br>
You can also define token-specific permissions there.
For more details, see the
[Strapi API Tokens Documentation](https://docs.strapi.io/cms/features/api-tokens).
### Examples
Some example requests using the [HTTPie CLI](https://httpie.io/cli):
#### Get the Main SpaceAPI Endpoint Info
```sh
http GET http://localhost:1337/api/spaceapi
```
#### Update the Hackspace State
```sh
API_TOKEN=your-token-here
http PUT \
http://localhost:1337/api/state \
Authorization:"Bearer $API_TOKEN" \
data:='{
"open": true,
"trigger_person": "Owner",
"message": "We are open!"
}'
```
#### Update a Sensor
```sh
API_TOKEN=your-token-here
# Discover the `documentId` for the Sensor
http GET \
http://localhost:1337/api/temperature-sensors \
Authorization:"Bearer $API_TOKEN"
DOCUMENT_ID=nrfn2800pexpwxuhqikzr7xa
http PUT \
http://localhost:1337/api/temperature-sensors/$DOCUMENT_ID \
Authorization:"Bearer $API_TOKEN" \
data:='{
"unit": "°C",
"value": 25
}'
```
### Caveats
#### Timestamps
Simple SpaceAPI does not attempt to be smart about timestamps,
so **any** successful request will update the corresponding `lastchange` field.
For example, if you set the hackspace state to "closed"
and repeat the **same request** the next day,
the `lastchange` field will be updated.
#### Validation
While Simple SpaceAPI performs basic data validation,
it's still possible to produce invalid SpaceAPI JSON.
Always validate your endpoint using the
[SpaceAPI Validator](https://spaceapi.io/validator/).
#### Units
Due to some Strapi limitations,
certain sensor units must be replaced with aliases in API requests:
- Humidity Sensor: use `percents` instead of `%`
- Wind Sensor: use `degree` instead of `°`
The main SpaceAPI endpoint will display the correct units.
#### Sensor Structure
While Simple SpaceAPI follows the general SpaceAPI format,
the internal structure of some sensors is simplified:
- Radiation sensors (`alpha`, `beta`, `gamma`, `beta_gamma`)
are unified into a single `radiation` type.
The exact subtype can be specified using the `type` field.
## Deployment
Coming soon.
