Trying to implement geo querying in my firestore db with the new version of firebase has been challenging. The code examples provided in the documentation reference an older version, making it difficult for me to understand how to use ".startAt" and ".endAt".
Could someone please clarify how to achieve this using firebase 9?
The startAt() method includes the starting point, while endAt() is used to set an end point for your query in order to refine the results.
Here's a snippet of code using startAt() (Web v9):
import { query, orderBy, startAt } from "firebase/firestore";
const q = query(citiesRef, orderBy("population"), startAt(1000000));
And here's an example utilizing endAt() (Web v9):
import { query, orderBy, endAt } from "firebase/firestore";
const q = query(citiesRef, orderBy("population"), endAt(1000000));
To learn more about paginating data with query cursors, you can refer to this documentation.
Additionally, as mentioned by @Nicholas Tower, be sure to explore other tabs for further examples in various languages and versions such as Web v8, Swift, Objective-C, Java, etc.
