# Shared Cost

Share costs with a group of people:

- Share according to people income,
- Monthly payments available,
- Statistics by month,
- Weekly activity sent by email.

## Getting started

Install nix:

```
curl https://nixos.org/nix/install | sh
```

Start the environment with:

```bash
./make start
```

Init the database with migration scripts:

```bash
sqlite3 database < server/migrations/1.sql
```

Inside the tmux session, add some users with sqlite after the migration is done:

```
sqlite3 database
insert into user(creation, email, name) values (datetime('now'), 'john@mail.com', 'John');
insert into user(creation, email, name) values (datetime('now'), 'lisa@mail.com', 'Lisa');
```

Later, stop the environment with:

```bash
./make stop
```

## Dist

```
make dist
```
