let express = require("express");
let app = express();
var firebase = require("firebase-admin");
require("firebase/database")


const serviceAccount = require("./keys.json");

let config = {
  credential: firebase.credential.cert(serviceAccount),
  databaseURL: "https://<MY_DB>.firebasedatabase.app",
};


firebase.initializeApp(config);

let db = firebase.database();

app.get("/", (req, res) => {
    db.ref().once("value")
    .then(function(snapshot) {
        console.log(snapshot.val())
    })
    res.send("Hello World!");
})

app.listen(5000, function () {
  console.log("Listened on port 5000!");
});
