Scicommons Integration Prototype

Prototype frontend + backend + database stack for Scicommons.

Current deployment shape:

React frontend -> FastAPI backend -> Postgres database

For the prototype, all three can run on one Arbutus server.

Server Setup

SSH to the Arbutus server at 134.87.8.193.

Clone the repo:

git clone git@github.com:m2b3/test_integration.git
cd test_integration

If GitHub SSH is not set up on the server, add a server SSH key to GitHub first.

Database

Start Postgres:

sudo docker compose up -d db

If Docker requires sudo every time, either keep using sudo docker ... or add the user to the Docker group and reconnect:

sudo usermod -aG docker $USER

Create/seed the database:

cd ~/test_integration/backend
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

DATABASE_URL=postgresql://scicommons:scicommons@localhost:5432/scicommons \
python setup_database.py

The setup script drops and recreates the prototype tables on every run.

Backend

Start the FastAPI backend:

cd ~/test_integration/backend
source .venv/bin/activate

DATABASE_URL=postgresql://scicommons:scicommons@localhost:5432/scicommons \
uvicorn app.main:app --host 0.0.0.0 --port 8000

Verify from the server:

curl http://localhost:8000/health
curl http://localhost:8000/tags

Verify externally:

curl http://134.87.8.193:8000/health

If local curl works but external curl hangs, open inbound TCP port 8000 in the Arbutus security/firewall settings.

Frontend

Create the frontend environment file:

cd ~/test_integration/frontend
echo "VITE_API_BASE_URL=http://134.87.8.193:8000" > .env

Install Node 22 if the server Node version is too old for Vite:

cd ~
curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
sudo apt install -y nodejs
node -v

Install dependencies and start the dev server:

cd ~/test_integration/frontend
npm install
npm run dev -- --host 0.0.0.0

Open:

http://134.87.8.193:5173

If the page is not reachable externally, open inbound TCP port 5173 in the Arbutus security/firewall settings.

Running With tmux

Use tmux so backend and frontend keep running after logout.

Create a session:

tmux new -s scicommons

In the first tmux window, run the backend:

cd ~/test_integration/backend
source .venv/bin/activate
DATABASE_URL=postgresql://scicommons:scicommons@localhost:5432/scicommons \
uvicorn app.main:app --host 0.0.0.0 --port 8000

Create a second tmux window:

Ctrl+b, then c

Run the frontend:

cd ~/test_integration/frontend
npm run dev -- --host 0.0.0.0

Detach from tmux:

Ctrl+b, then d

Reconnect later:

tmux attach -t scicommons

Useful tmux commands:

tmux ls
tmux kill-session -t scicommons

Main API Endpoints

GET  /health
GET  /tags
GET  /sources
GET  /articles
GET  /articles?tags=biology,chemistry&match=or
GET  /users/{user_id}/feed
GET  /users/{user_id}/tags
GET  /users/{user_id}/recently-viewed
POST /users/{user_id}/recently-viewed
POST /login
PUT  /users/{user_id}/tags

Notes

• Backend runs on port 8000.
• Frontend dev server runs on port 5173.
• Postgres runs on local port 5432.
• Frontend .env is intentionally not committed; recreate it on each server.
• This is a prototype deployment. Later, frontend/backend/database can be separated if needed.
