How do I update a Firestore document in Vue.js?

To update a Firestore document in Vue.js, you can use the update method provided by the Firestore SDK.

Can you show me a code example?

Sure! Here's a simple example:

const db = firebase.firestore();
const docRef = db.collection('yourCollection').doc('yourDocumentId');

// Update the document
docRef.update({
  fieldName: 'newValue'
})
.then(() => {
  console.log('Document successfully updated!');
})
.catch((error) => {
  console.error('Error updating document: ', error);
});

What if the document doesn't exist?

If the document doesn't exist, the update method will throw an error. You can use set with { merge: true } to create it if it doesn't exist.
