## Getting Started
To get a local copy up and running, follow these steps.
### Prerequisites
- Elixir and Erlang/OTP
- We recommend using [asdf](https://github.com/asdf-vm/asdf) to install [Elixir](https://github.com/asdf-vm/asdf-elixir) and [Erlang/OTP](https://github.com/asdf-vm/asdf-erlang).
- Keep in mind that each Elixir version supports [specific Erlang/OTP versions](https://hexdocs.pm/elixir/compatibility-and-deprecations.html#between-elixir-and-erlang-otp).
- Make sure you have at least **Elixir 1.12** installed to run Algora TV.
- PostgreSQL
- FFmpeg
- ImageMagick
- OBS Studio (recommended for testing livestreaming features)
### Setting up the project
1. Clone the repo and go to the project folder
```sh
git clone https://github.com/algora-io/tv.git; cd tv
```
2. Fetch dependencies
```sh
mix deps.get
```
**Note:** If you're using an Apple machine with an ARM-based chip, you need to install the Rust compiler and run `mix compile.rambo`
3. Initialize your `.env` file
```sh
cp .env.example .env
```
4. Create your database
```sh
sudo -u postgres psql
```
```sql
CREATE USER algora WITH PASSWORD 'password';
CREATE DATABASE tv;
GRANT ALL PRIVILEGES ON DATABASE tv TO algora;
```
5. Paste your connection string into your `.env` file
```env
DATABASE_URL="postgresql://algora:password@localhost:5432/tv"
```
6. Run migrations and seed your database
```sh
env $(cat .env | xargs -L 1) mix ecto.setup
```
7. Start your development server
```sh
env $(cat .env | xargs -L 1) iex -S mix phx.server
```
### Setting up external services
Some features of Algora TV rely on external services. If you're not planning on using these features, feel free to skip setting them up.
#### GitHub
GitHub is used for authenticating users.
[Create a GitHub OAuth app](https://github.com/settings/applications/new) and set
- Homepage URL: http://localhost:4000
- Authorization callback URL: http://localhost:4000/oauth/callbacks/github
Once you have obtained your client ID and secret, add them to your `.env` file.
```env
GITHUB_CLIENT_ID=""
GITHUB_CLIENT_SECRET="..."
```
#### Tigris
Tigris is used for storing and delivering livestreams and other media.
[Create a public Tigris bucket](https://console.tigris.dev/) to obtain your secrets and add them to your `.env` file.
```env
AWS_ENDPOINT_URL_S3="https://fly.storage.tigris.dev"
AWS_REGION="auto"
AWS_ACCESS_KEY_ID="tid_..."
AWS_SECRET_ACCESS_KEY="tsec_..."
BUCKET_MEDIA="..."
```
