Firestore Censor

This repo contains firestore cloud functions, specifically the censor function that gets triggered everytime new message is being written to firestore. The censor function calls the backend service to get prediction of message class, and writes back the result to firestore.

Prerequisite

npm install -g firebase-tools

Developing

  1. change working directory to functions folder
  2. run npm install

  3. Fill form with these data, then save. This will create a chatroom collection.

    • Collection ID: chatRooms
    • Document ID: chatroom1

  4. Click start collection in chatroom1 document
