Heres an example of pagination in Firestore using JavaScript

​

const db = firebase.firestore();

const collection = db.collection("items");

​

// Get the first 10 documents

const firstBatch = await collection.limit(10).get();

​

// Get the next 10 documents

const nextBatch = await collection.startAfter((link unavailable)[9]).limit(10).get();

​

// Get the next 10 documents

const nextBatch = await collection.startAfter((link unavailable)[9]).limit(10).get();

​

// And so on...

​

In this example, we use the limit() method to get the first 10 documents. Then, we use the startAfter() method to get the next 10 documents, starting from the last document in the previous batch. We can continue this process to paginate through the entire collection.

​

Note that we also use the get() method to retrieve the documents from the query. This method returns a Promise that resolves with a QuerySnapshot object, which contains the documents. We can then use the docs property of the QuerySnapshot object to access the documents.
