To get a local copy up and running, follow these steps.

• Elixir and Erlang/OTP
  • We recommend using asdf to install Elixir and Erlang/OTP.
  • Keep in mind that each Elixir version supports specific Erlang/OTP versions.
  • Make sure you have at least Elixir 1.12 installed to run Algora TV.
• PostgreSQL
• FFmpeg
• ImageMagick
• OBS Studio (recommended for testing livestreaming features)

1. Clone the repo and go to the project folder

   git clone https://github.com/algora-io/tv.git; cd tv

2. Fetch dependencies

   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

   cp .env.example .env

4. Create the database user that will manage the database

   sudo -u postgres psql

   CREATE USER algora WITH PASSWORD 'password';
   ALTER USER algora WITH CREATEDB;
   \q

   Update the .env file as needed with the username and password you used.

5. Set up and seed your database

   env $(cat .env | xargs -L 1) mix ecto.setup

6. Start your development server

   env $(cat .env | xargs -L 1) iex -S mix phx.server

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 is used for authenticating users.

Create a GitHub OAuth app and set

• Homepage URL: https://localhost:4000
• Authorization callback URL: https://localhost:4000/oauth/callbacks/github

Once you have obtained your client ID and secret, add them to your .env file.

GITHUB_CLIENT_ID=""
GITHUB_CLIENT_SECRET="..."

Tigris is used for storing and delivering livestreams and other media.

Create a public Tigris bucket to obtain your secrets and add them to your .env file.

AWS_ENDPOINT_URL_S3="https://fly.storage.tigris.dev"
AWS_REGION="auto"
AWS_ACCESS_KEY_ID="tid_..."
AWS_SECRET_ACCESS_KEY="tsec_..."
