## Installation

### 0 | Requirements
Meeting Planner runs on virtually any system where Node.js is supported.
This means it runs on Linux, macOS, Windows as well as container solutions such as Docker / Kubernetes and Heroku.

**Versions**
- Postgres 9.5 or later
- NodeJS 10.12 or later

*[KnexJS](https://knexjs.org/), the database driver used is compatible with other databases like MySQL.
With small adaptation, it should be possible to use them, but this has not been tested.*

### 1 | Configure Postgres to use UTC

** Make sure that Postgres database used is configured to UTC **
`SET TIME ZONE 'UTC';`

See [Postgres Documentation](https://www.postgresql.org/docs/current/sql-set.html)

### 2 | Create and/or configure environement variables

- Create a `.env` file at the root of the backend folder
- Replace all variables noted with `$` below, and save it to the `.env` file

```
NODE_ENV=development // This can't be changed for now
PORT=$port_number
DATABASE_URL=postgres://$db_user:$db_user_password@$hostname:5432/$db_name
JWT_SECRET=$long_random_characters
```
### 3 | Installation of packages with npm
- `npm i`

### 4 | Migrate tables to database
- `npx knex migrate:latest`

### 5 | Seed database with dummy content **(optional)**
Running this will add some accounts along with some meetings.
- `npx knex seed:run`
