Firestore cloud function to update Algolia index on change

firestore-update-algolia.js

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
import * as algoliasearch from 'algoliasearch';

admin.initializeApp();

const client = algoliasearch(
    functions.config().algolia.app_id,
    functions.config().algolia.api_key
);

const index = client.initIndex('movie_title');

exports.updateMovies = functions.firestore
    .document('movies/{movieId}')
    .onUpdate((change, context) => {
        const newData = change.after.data();
        const object = {
            objectID: context.params.movieId,
            ...newData
        }

        return index.partialUpdateObject(object);
    })

Thanks!!

Hi, how do you add algolia info to the config object?

if you have the algolia APP ID and ADMIN API KEY. I believe I got it working by typing this in the command line:
firebase functions:config:set algolia.app_id="APP_ID" algolia.api_key="API_KEY"
