# Pica - Backend for Megpie budgeting app

... some description

### Prerequisites

- fcgi
- nlohmann_json


### Building

```
$ git clone https://git.macaw.me/blue/pica
$ cd pica
$ mkdir build
$ cd build
$ cmake ..
$ cmake --build .
```

### Usage

#### Webserver
First you need a webserver. In this example I'm going to use apache.

Install apache from your package manager.

Create a file like this in apache config dir (in my case it's `/etc/httpd/conf/extra/fcgi-pica.conf`)
```
<Location /pica>
    ProxyPass "unix:/run/pica/pica.sock|fcgi://localhost"
    ProxyPassReverse "http://localhost"
</Location>
```

Incude this file from apache config file (in my case it's `/etc/httpd/conf/httpd.conf`)
```
Include conf/extra/fcgi-pica.conf
```

Also you need to have 2 modules enabled `proxy` and `proxy_fcgi`, usually you need to uncomment following lines in `/etc/httpd/conf/httpd.conf`
```
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
```

In case you use debian-like distro (ubuntu) you should use `a2enmod` command instead:
```
# a2enmod proxy_fcgi
```
This should enable both modules, because module `proxy_fcgi` has module `proxy` as a dependency.

Start apache

```
$ sudo systemctl start httpd
```

#### Creating a directory
Next you need to create a directory for pica socket file
```
# mkdir /run/pica
# chown <your user> /run/pica
```

#### Running an app
At this stage we're redy to run an app
```
$ cd build
$ ./pica
```
