KeyNodeFinder

Search engine with a React frontend, Keycloak authentication, a Node.js backend, and a PostgreSQL database

1. Keycloak authentication

• Pull and run docker keycloak

docker pull jboss/keycloak
docker run -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=admin -p 8180:8080 jboss/keycloak

• Set up Realm, client and users.

2. Server side (backend)

• Initializes a new Node.js project and install dependencies

npm init -y
npm i express cors jsonwebtoken dotenv pg

• Set up in .env: keycloak public key and PSQL variables (user, host, db_name, db_password).

• Run server

node server.js

3. Client side (frontend)

• Create a new React application and install dependencies.

npx create-react-app .
npm install keycloak-js axios

• Start client

npm start

4. PostgreSQL

• Install PostgreSQL
• For this tutorial I created a simple table as an example:

CREATE TABLE biosample (
    id SERIAL PRIMARY KEY,
    biosample VARCHAR(30),
    bioproject VARCHAR(30),
    drr VARCHAR(30),
    email VARCHAR(100)
);
INSERT INTO biosample (biosample, bioproject, drr, email) VALUES ('BS12345', 'BP12345', 'DRR12345', 'newuser@server.com');
