@ -11,219 +11,6 @@ The client-side browser application is powered by [Leaflet](https://leafletjs.co
Note that this project is _not_ responsible for entering data into the database. This project's purpose is simply to display the data.
## System Requirements
In order to run this program, you'll need the following:
- Git
- Bash (if on Windows, try [Git Bash](https://gitforwindows.org/)) - the build script is written in Bash
- [composer](https://getcomposer.org/) - For the server-side packages
- [Node.JS](https://nodejs.org/)
- [npm](https://npmjs.org/) - comes with Node.JS - used for building the client-side code
- A [MariaDB](https://mariadb.com/) server with a database already setup with the schema data in it. Please get in contact with [ConnectedHumber](https://connectedhumber.org/) for information about the database schema and structure.
## Getting Started
The client-side code requires building. Currently, no pre-built versions are available (though these can be provided upon request), so this must be done from source. A build script is available, however, which automates the process - as explained below.
### System Requirements
- PHP-enabled web server
- _Nginx_ + _PHP-FPM_ is recommended
- Apache works too
- MariaDB database with the appropriate table structure pre-loaded
- PHP 7+
- Node.JS (preferably 10+) + npm 6+ (for installing & building the client-side app code)
- [Composer](https://getcomposer.org/) (for installing server-side dependencies)
- PHP modules:
- `pdo-mysql` (for the database connection)
### Installation
1. Start by cloning this repository:
```bash
git clone https://github.com/ConnectedHumber/Air-Quality-Web.git
```
2. `cd` into the root of the cloned repository. Then install the dependencies (these are installed locally):
```bash
./build setup setup-dev
```
3. Build the client-side application:
```bash
# For development, run this:
./build client
# For production, run this:
NODE_ENV=production ./build client
# If you're actively working on the codebase and need to auto-recompile on every change, run this:
./build client-watch
```
4. Change the ownership to allow your web server user to access the created directory. Usually, the web server will be running under the `www-data` user:
```bash
sudo chown -R www-data:www-data path/to/Air-Quality-Web
```
5. Edit `data/settings.toml` to enter your database credentials.
You can edit other settings here too. See `settings.default.toml` for the settings you can change, but do **not** edit `settings.default.toml`! Edit `data/settings.toml` instead. You'll probably want to give the entire default settings file a careful read.
6. Configure your web server to serve the root of the repository you've cloned if you haven't already. Skip this step if you cloned the repository into a directory that your web server already serves.
7. Disallow public access to the private `data` directory.
In Nginx:
```nginx
# Put this inside the "server { }" website definition block:
# The "server { }" block can usually be found somewhere in /etc/nginx on Linux machines, and may have a "server_name" directive specifying the domain name it's serving if multiple websites are configured.
location ^~ /path/to/data/directory {
deny all;
}
```
In Apache:
```htaccess
# Create a file called ".htaccess" with this content inside the data/ directory
Require all denied
```
8. Test the application with an API call. If this returns valid JSON, then you've set it up correctly
```
http://example.com/path/to/Air-Quality-Web/api.php?action=list-devices
```
9. (Optional) Setup HTTPS:
```bash
sudo apt install certbot
# On Nginx:
sudo certbot --nginx --domain example.com
# On Apache:
sudo certbot --apache --domain example.com
```
## API
The server-side API is accessed through `api.php`, and supports a number of GET parameters. The most important of these is the `action` parameter, Which determines what the API will do. The following values are supported:
### version
> Returns the version of the application.
_No parameters are currently supported by this action._
Examples:
```
https://example.com/path/to/api.php?action=version
```
### fetch-data
> Fetches air quality data from the system for a specific data type at a specific date and time.
Parameter | Type | Meaning
--------------------|-----------|---------------------
`datetime` | date/time | Required. Specifies the date and time for which readings are desired. For current data use the special keyword `now`.
`reading_type` | string | Required. Specifies the type of reading desired.
`format` | string | Optional. Specifies the format that the response will be returned in. Valid values: `json`, `csv`. Default: `json`.
Examples:
```
https://example.com/path/to/api.php?action=fetch-data&datetime=2019-01-03%2007:52:10&reading_type=PM10
https://example.com/path/to/api.php?action=fetch-data&datetime=now&reading_type=PM10
```
### list-devices
> Fetches a list of devices currently in the system.
Parameter | Type | Meaning
--------------------|-----------|---------------------
`only-with-location`| bool | Optional. If present only devices with a defined location will be returned. Useful for getting a list of devices to place on a map.
`format` | string | Optional. Specifies the format that the response will be returned in. Valid values: `json`, `csv`. Default: `json`.
Examples:
```
https://example.com/path/to/api.php?action=list-devices
https://example.com/path/to/api.php?action=list-devices&only-with-location=yes
```
### device-info
> Gets (lots of) information about a single device.
Parameter | Type | Meaning
--------------------|-----------|---------------------
`device-id` | int | Required. The id of the device to get extended information for. See the `list-device` action for how to get a hold of one.
Examples:
### list-reading-types
> Lists the different types of readings that can be specified.
Parameter | Type | Meaning
--------------------|-----------|---------------------
`device-id` | int | Optional. If specified, this filters the list of measurement types to list only those reported by the device with the specified id.
`format` | string | Optional. Specifies the format that the response will be returned in. Valid values: `json`, `csv`. Default: `json`.
```
https://example.com/path/to/api.php?action=list-reading-types
https://example.com/path/to/api.php?action=list-reading-types&device-id=22
https://example.com/path/to/api.php?action=list-reading-types&device-id=54
```
### device-data-bounds
> Gets the start and end DateTime bounds for the data recorded for a specific device.
Parameter | Type | Meaning
--------------------|-----------|---------------------

```
https://example.com/path/to/api.php?action=device-data-bounds&device-id=18
https://example.com/path/to/api.php?action=device-data-bounds&device-id=11
```
### device-data
> Gets data by device given a start and end time.
Parameter | Type | Meaning
--------------------|-----------|---------------------
`device-id` | int | The id of the device to get data for.
`reading-type` | string | The type of reading to obtain data for.
`start` | datetime | The starting datetime.
`end` | datetime | The ending datetime.

`format` | string | Optional. Specifies the format that the response will be returned in. Valid values: `json`, `csv`. Default: `json`.
```
https://example.com/path/to/api.php?action=device-data&device-id=18&reading-type=PM25&start=2019-01-19T18:14:59.992Z&end=2019-01-20T18:14:59.992Z

- Node.JS (preferably 10+) + [npm](https://npmjs.org/) 6+ (for installing & building the client-side app code)
- [Node.JS](https://nodejs.org/)
- [Composer](https://getcomposer.org/) (for installing server-side dependencies)
