Counter SDK for backend services like "node.js" about extensions HOT 7 CLOSED

Hi I made a quick work around function from the SDK to let this extension work on javascript Firebase functions.

const uuidv4 = require('uuid/v4');
const admin = require('firebase-admin');
const functions = require('firebase-functions');

exports.test = functions.https.onCall(async (data, context) => {
return await increment('visits', 'pages/clicks/test', 1);
});

function increment(field, path, val) {
const db = admin.firestore();
const increment = admin.firestore.FieldValue.increment(val);
const update = field.split(".").reverse().reduce((value, name) => ({[name]: value}), increment);
return doc.collection('_counter_shards_').doc(uuidv4()).set(update, {merge: true});
}

It may not be the best solution yet but works.

XFN Team: Would this be an additional "client" in the project, or would it be appropriate to adapt the web script to work in a Node environment?

I think it would be better to adapt the web script to work in a Node environment.

I have tested the above code, and it triggers the aggregation function every time the "test" onCall function is called.

Won't increment provided by admin sdk work for distributed counter tasks?

@voxelbusters FieldValue.increment is the right thing for incrementing a value, but it doesn't solve the underlying problem that a Firestore document can only be updated about once per second. More info here.

We're not planning an official implementation for any other clients at this time, and we've changed the name of the "Web Client SDK" to "client sample" to try to make that a little more clear.

The typescript sample implementation is a good starting place for a node.js implementation of the counter.

In the future, I'd like to see how much of this logic we can move off of the client and into something like a callable function that's installed by the extension itself.
