Firestore basics

fireystore.js

// Edited this from VS code
var firebaseConfig = {};

// Initialize Firebase
firebase.initializeApp(firebaseConfig);

const db = firebase.firestore();

// Read
db.collection("cafes")
  .get()
  .then((snapshot) => {
    snapshot.docs.forEach((doc) => console.log(doc.data()));
  });

// Delete
db.collection("cafes").doc(id).delete();

// Create
db.collection("cafes").add({ name: "Me", city: "My city" });

// Search
db.collection("cafes")
  .where("name", "==", "mario")
  .get()
  .then((snapshot) => {
    snapshot.docs.forEach((doc) => console.log(doc.data()));
  });

// Deep search
db.collection("cafes")
  .orderBy("city")
  .onSnapshot((snap) => {
    let changes = snap.docChanges();
    // console.log(changes);

    changes.forEach((change) => {
      // console.log(change.doc.data());
      // console.log(change.type);
    });
  });

// Update
db.collection("cafes")
  .doc("vsgregerr")
  .update({ city: "Place where someone used to live" });
