# LocalSpend (Server)

Looking to discover if the value of spending local can be measured, understood and shown.

This repository contains the server application for the LocalSpend system. See also:

* the [Web application](https://github.com/Pear-Trading/Foodloop-Web); and
* the [mobile application](https://github.com/Pear-Trading/LocalSpend-Tracker).

## Technology Stack

The server app. is written in [Perl](https://www.perl.org/).

Admin. portal pages are templated using [HTML::EP](https://metacpan.org/pod/distribution/HTML-EP/lib/HTML/EP.pod).

## Features

This server app. provides:

- user creation, updating and deletion;
- organisation creation, updating and deletion;
- an admin. management portal;
- transaction logging;
- transaction history analysis; and
- leaderboard generation.

## Installation

1. Clone the repo. to your dev. environment (`git clone git@github.com:Pear-Trading/FoodLoop-Server.git`);
1. enter the new directory (`cd FoodLoop-Server`);
1. install the dependencies:
    - ```shell script
      cpanm --installdeps . \
      --with-feature=sqlite \
      --with-feature=codepoint-open
      ```
    - if you are using a PostgreSQL database, replace `--with-feature=sqlite` 
      with `--with-feature=postgres`.
1. install the database:
    - run `./script/deploy_db install -c 'dbi:SQLite:dbname=foodloop.db'`;
    - development supports both SQLite and PostgreSQL (production uses PostgreSQL);
    - for this example we will use SQLite; so
    - as the default config. is set up for this, no configuration changes are 
      needed initially.
1. set up the development users:
    - `./script/pear-local_loop dev_data --force`
    - **DO NOT RUN ON PROD!**
1. start the [Minion](https://docs.mojolicious.org/Minion) job scheduler:
    - `./script/pear-local_loop minion worker`
1. import ward data:
    1. Download the CSV(s) from [here](https://www.doogal.co.uk/PostcodeDownloads.php); and
    1. run the following command:
        - ```shell script
		      ./script/pear-local_loop minion job \
		      --enqueue 'csv_postcode_import'  \
		      --args '[ "⟨ path to CSV ⟩" ]'
		      ```
1. set up postcodes:
    1. import [Code-Point Open](https://www.ordnancesurvey.co.uk/business-government/products/code-point-open):
    		- a copy is included in `etc/`;
    		- run `./script/pear-local_loop codepoint_open --outcodes LA1`
		1. assign postcodes:
    		- ```shell script
      	  ./script/pear-local_loop minion job \
          --enqueue entity_postcode_lookup
     		  ```

## Configuration

App. configuration settings are found in `pear-local_loop.⟨environment⟩.conf`.

[Firebase Cloud Messaging](https://firebase.google.com/docs/cloud-messaging/) 
(FCM) credentials should be placed in a file called `localspend-47012.json` in 
root. This file is not tracked by Git; ask another developer for a copy.

Default user credentials are found in `lib/Pear/LocalLoop/Command/dev_data.pm`.

## Usage

- Run `./script/pear-local_loop minion worker` to start the Minion asynchronous 
  job scheduler; and
- run `morbo script/pear-local_loop -l http://*:3000` to start the server on 
  the specific hostname and port.

### Database Scripts

To upgrade the database after making changes to commit:

1. Increment the `$VERSION` number in `lib/Pear/LocalLoop/Schema.pm`;
1. run `./script/deploy_db write_ddl -c 'dbi:SQLite:dbname=foodloop.db'`; and
1. run `./script/deploy_db upgrade -c 'dbi:SQLite:dbname=foodloop.db'`.

Run `./script/pear-local_loop recalc_leaderboards` to update the leaderboards.

## Testing

- Run `prove -lr -j 9` to run the full test suite using
  [Test-Simple](https://metacpan.org/release/Test-Simple) (when using an SQLite 
  database); and
- run `PEAR_TEST_PG=1 prove -lr -j 9` to run the full test suite (when using a 
  PostgreSQL database).

Test files are found in the `t/` directory.

## Code Formatting

Run `for f in ./lib/**/*.pm; do perltidy -b $f; done` to format all Perl files
with [Perl-Tidy](https://metacpan.org/release/Perl-Tidy) (there is no built-in
option to format files recursively). This will produce backup files with `.bak`
extensions, so run `rm -r *.bak` to clean up your local copy if you are happy
with the formatted files.

Run `perlcritic lib` to lint all Perl files with [Perl-Critic](https://metacpan.org/release/Perl-Critic).
