Orcasite

Website License

Zulip PRs Welcome OpenSSF Scorecard

This repo specifies the web backend and frontend for the Orcasound app that plays a live audio stream through the user's browser of choice. The backend is an Elixir app using the Phoenix framework. The frontend is built in Next.js.

Contributing

Please check out the CONTRIBUTING doc for tips on making a successful contribution, as well as learning resources!

Quick Start:

  1. Load the Docker Configuration: docker-compose up
  2. Wait for containers to start up
  3. Navigate to localhost:3000 to view the website
  4. Navigate to localhost:4000 to access the API server

Note This assumes you have installed docker and docker-compose.

Running in Docker

Docker is the quickest way to get the project up and running, especially if you haven't already set up Erlang/Elixir/Node. The only requirement is that you have both docker and docker-compose installed on your machine.

Once you clone the repository, you can just run docker-compose in the root directory:

docker-compose up

This will build an image locally with all the dependencies you need. It will also pull a pre-built image from Docker Hub for the database, automatically configure everything, and both the Phoenix and Next.js servers. The orcasite page will be accessible at http://localhost:3000 as soon as the web container finishes starting up.

Developing

The quick start setup is great for getting the project up and running, but if you want to do development, you'll want to be able to modify the source code without re-building an entire Docker image.

Setup options

There are several options for how to set up your dev environment:

Once you have one of these up and running, see the Getting everything running section for how to start the project.

Using VS Code

This project comes with a devcontainer.json configuration which can be used with VS Code. This takes care of all the docker-compose stuff in the background so you don't have to worry about it. When you open the project in VS Code, it should prompt you to start it in a dev container (assuming you've installed docker and the dev containers extension). Once the dev container starts, you can open a new terminal window in VS Code to run commands. See the commands below for how to get everything started.

Using docker-compose directly

If you prefer not to use VS Code dev containers, the easiest way to develop in docker is by starting up docker-compose manually (using the dev compose file):

docker-compose -f docker-compose.yml -f docker-compose.dev.yml up -d

Note You can also set the COMPOSE_FILE environment variable to avoid having to specify the compose files every time. This one-liner will do that for you no matter which subdirectory you're in:

export COMPOSE_FILE=`git rev-parse --show-toplevel`/docker-compose.yml:`git rev-parse --show-toplevel`/docker-compose.dev.yml

After setting COMPOSE_FILE, you can just run docker-compose up -d from anywhere in the project.

Once you have the services started, you can start a session inside the web container:

docker-compose exec web bash

From here you can run the commands below to get everything started.

Note The docker-compose setup uses bind mounting for the source files, which means if you edit the source on your host file system, the changes will get picked up and live reloaded in your browser.

Set up directly on machine

If Docker doesn't suit your needs, you can follow these instructions to get everything running directly on your machine.

Language

You will need to install Erlang, Elixir, and Node.js. You can use a tool like asdf to manage your language dependencies.

Language-level dependencies can be found under .tool-versions.

Database

You will need to install Postgres and set up the postgres user with a password. The default connection details are:

username: "postgres"
password: "postgres"
database: "orcasite_dev"
hostname: "localhost"
port: 5432

You can pass in custom values using env variables. Full details can be found in dev.exs.

Orcasite uses PostGIS for location data inside of Postgres. To install on MacOS, run

brew install postgis

Getting everything running

Once you have your environment setup via one of the options above, you can start the project. You'll need to run both the Phoenix server and the Next.js server.

Server

In a new terminal session, from the root directory:

> cd server/
> mix deps.get
> mix ecto.setup
> iex -S mix phx.server

Note For future runs, you can skip running the mix commands and just start the server with iex -S mix phx.server

The server should soon be available at http://localhost:4000.

UI

Open another terminal session and run these commands to start Next.js:

> cd ui/
> npm i
> npm run dev

Once everything finishes starting up, you'll be able to access the UI at http://localhost:3000.

Tests

UI

The new version (v3) is currently under development, rapidly changing, and has no tests yet.

Deployment

For the moment, this app is running in a Heroku instance with mix phx.server. To access the console, run:

heroku run FEED_STREAM_QUEUE_URL="" REDIS_URL="" POOL_SIZE=2 iex -a <app name> -- -S mix

The POOL_SIZE config var is necessary due to the current Postgres db having 20 connections. You can read more about it here.

Emails

Orcasite uses MJML for email templating. There are a few online MJML renderers, including: mjml.io and grapes.js

API

An API is available using the JSON API spec. For access to available endpoints, navigate to the server's /api/json/swaggerui or /api/json/redoc path for documentation and examples. As an example, you may access the full list of feeds with:

curl -s https://beta.orcasound.net/api/json/feeds \
-H "Content-Type: application/vnd.api+json" \
-H "Accept: application/vnd.api+json"
