We all know that Firebase usually stores all the logics and codes on the client-side, no matter which development (mobile or web) you are in. Each code goes directly to either the browser or the mobile device. Storing the code on the client end usually raises the risk.To tackle such concerns and issues, Firebase recently introduced Cloud Functions.
Why to use Firebase Cloud Functions?
Firebase Cloud Functions are serverless functions that allow you to store your business logic in a secure environment (Google Servers). Such functions run all the code safely and regular users won’t have access to your function code.
You can invoke these functions either via HTTP calls, Triggers or Cron Jobs.
