# The Biergarten App

## About

The Biergarten App is a web application designed for beer lovers to share their favorite
brews and breweries with like-minded people online.

This application's stack consists of Next.js, Prisma and Neon Postgres. I'm motivated to
learn more about these technologies while exploring my passion for beer.

I've also incorporated different APIs into the application, such as the Cloudinary API for
image uploading, the SparkPost API for email services as well as Mapbox for geolocation
and map data.

To handle serverless functions (API routes), I use the next-connect package.

On the client-side, I use Tailwind CSS, Headless UI and Daisy UI for styling to create a
visually appealing and user-friendly interface.

I'm sharing my code publicly so that others can learn from it and use it as a reference
for their own projects.

### Some beer terminology

In this app you will encounter various beer related terms. Here is a list of terms used in
this app and their definitions.

#### ABV

[Alcohol by volume](https://en.wikipedia.org/wiki/Alcohol_by_volume) (abbreviated as ABV)
is a standard measure of how much alcohol (ethanol) is contained in a given volume of an
alcoholic beverage (expressed as a volume percent).

#### IBU

The
[International Bitterness Units](https://en.wikipedia.org/wiki/Beer_measurement#Bitterness)
scale, or IBU, is used to approximately quantify the bitterness of beer. This scale is not
measured on the perceived bitterness of the beer, but rather the amount of a component of
beer known as iso-alpha acids.

- [npm (version 8 or higher)](https://www.npmjs.com/get-npm)

You will also need to create a free account with the following services:

- [Cloudinary](https://cloudinary.com/users/register/free)
- [SparkPost](https://www.sparkpost.com/)
- [Neon Postgres](https://neon.tech/)
- [Mapbox](https://account.mapbox.com/auth/signup/)

### Setup

1. Clone this repository and navigate to the project directory.

```bash
git clone https://github.com/aaronpo97/the-biergarten-app
cd the-biergarten-app
```

2. Run the following command to install the dependencies.

```bash
npm install
```

3. Run the following script to create a `.env` file in the root directory of the project
   and add the following environment variables. Update these variables with your own
   values.

```bash
echo "BASE_URL=
NEXT_PUBLIC_CLOUDINARY_CLOUD_NAME=
CLOUDINARY_KEY=
CLOUDINARY_SECRET=
CONFIRMATION_TOKEN_SECRET=
RESET_PASSWORD_TOKEN_SECRET=
SESSION_SECRET=
SESSION_TOKEN_NAME=
SESSION_MAX_AGE=
NODE_ENV=

POSTGRES_PRISMA_URL=
POSTGRES_URL_NON_POOLING=
SHADOW_DATABASE_URL=

ADMIN_PASSWORD=

MAPBOX_ACCESS_TOKEN=

SPARKPOST_API_KEY=
SPARKPOST_SENDER_ADDRESS=" > .env
``` 

### Explanation of environment variables

- `BASE_URL` is the base URL of the application.
  - For example, if you are running the application locally, you can set this to
    `http://localhost:3000`.
- `NEXT_PUBLIC_CLOUDINARY_CLOUD_NAME`, `CLOUDINARY_KEY`, and `CLOUDINARY_SECRET` are the
  credentials for your Cloudinary account.
  - You can create a free account [here](https://cloudinary.com/users/register/free).
- `CONFIRMATION_TOKEN_SECRET` is the secret used to sign the confirmation token used for
  email confirmation.
  - You can generate a random string using the`openssl rand -base64 127` command.
- `RESET_PASSWORD_TOKEN_SECRET` is the secret used to sign the reset password token.
  - You can generate a random string using the `openssl rand -base64 127` command.
- `SESSION_SECRET` is the secret used to sign the session cookie.
  - Use the same command as above to generate a random string.
- `SESSION_TOKEN_NAME` is the name of the session cookie.
  - You can set this to `biergarten`.
- `SESSION_MAX_AGE` is the maximum age of the session cookie in seconds.
  - You can set this to `604800` (1 week).
- `POSTGRES_PRISMA_URL`is a pooled connection string for your Neon Postgres database.

  database used for migrations.
- `SHADOW_DATABASE_URL` is a connection string for a secondary database used for
  migrations to detect schema drift.
  - You can create a free account [here](https://neon.tech).
  - Consult the [docs](https://neon.tech/docs/guides/prisma) for more information.
- `MAPBOX_ACCESS_TOKEN` is the access token for your Mapbox account.
