Surprisingly simple method to increase Firestore performance & reduce cost

• firebase-js-sdk

  Firebase Javascript SDK

  

While Firebase's Firestore is pretty fast to begin with, because it doesn't support automatically joining data together (i.e. SQL joins) a common workaround is to use observables to do something like the following (example taken from rxFire docs):

• fast-json-stable-stringify

  2 275 0.0 JavaScript

  Deterministic JSON.stringify() - a faster version of @substack's json-stable-strigify without jsonify.

Now, when the ClientService#getClient() method is called, the method arguments and identifiers are passed to the query cache service along with a query factory function. The query cache service uses the fast-json-stable-stringify library to stringify the query's identifying information and use this string as a key to cache the query's observable. Before caching the query, the observable is modified in the following ways:

• SurveyJS
