Audius frontend gateway for 3p traffic

There are two modes of operation of General Admission

1. As a first-layer proxy

   • Client sends a request to GA
   • GA identifies User-Agent and redirects traffic accordingly
     • Humans are forwarded to the DApp
     • Bots / etxc. are forwarded to the internal Node server that handles OG tags or to the embed player

2. (current) As a host/origin of secondary endpoints for the App (Embed Player, OG Meta Tags, etc.)

   • Client sends a request to a CDN with something like Lambda@Edge of CloudFlare Workers
   • CDN identifies User-Agent and optionally redirects traffic to GA
   • GA picks up on a subset of requests and forward to the internal Node server or the embed player

Getting started

git clone git@github.com:AudiusProject/general-admission.git
cd general-admission

cp .env.stage .env # or .env.prod

docker compose up --build -d

visit http://localhost:9001 (it may be 9000, check by running docker ps).

and to stop it:

docker compose down

or if you want to run just the node service:

# Will be running on port 8000
npm run start

# or with docker

docker build -t ga-node .
docker run --rm ga-node -p 8000:8000 -d

Against a local dapp

1. Run the dapp locally
2. Set APP_URL env var in .env to http://docker.for.mac.localhost:{DAPP_PORT}

ssh prod-general-admission # or stage-general-admission

# Navigate to GA folder
cd general-admission

# Pull the latest code
git pull

# Update env files here if needed
cp .env.prod .env # or .env.stage

# Deploy
docker compose up -d --build node
