kandi X-RAY | atlas Summary

atlas is a Java library typically used in Plugin applications. atlas has no bugs, it has no vulnerabilities, it has a Permissive License and it has high support. However atlas build file is not available. You can download it from GitHub.
A powerful Android Dynamic Component Framework. Atlas is an Android client-side containerization framework. we call it android dynamic component framework. Atlas provides decoupled, component, and dynamic support. Atlas covers various issues in the project coding period, Apk run-time and follow-up operation and maintenance. In the project period, Atlas enable engineers independent development, independent debug, because their project were physical isolation. In the apk run-time, Atlas has complete component life cycle, class isolation and other mechanisms. In the operation and maintenance period, Atlas provide rapid incremental update and rapid upgrade capacity. Atlas put the work into the project period as much as possible, to ensure runtime simple and stable, maintenance easy. Compared with multidex solution, Atlas not only solved the limitation of the method count(65535), but also clarified the boundary of development, provied the powerful capabilities for Android development, such as Parallel Iteration, Rapid Development, Flexible Release, Dynamically Update, Quick Fix Online Failure. Unlike some Android plugin frameworks, Atlas is a component framework (we call it Bundle), Atlas is not a multi-process framework. You can see there were three main library in this project (atlas-core/atlas-update/atlas-gradle-plugin).

atlas Key Features

atlas-core: This is client-side core library, it's job is to install each bundle, load the classes and resources on-demand when runtime.

atlas-update: This is client-side update library, which provide dexmerge capacity for update or upgrade.

atlas-gradle-plugin: This is Android Studio Gradle Plugin for engineers developing in project period, because we change some android default package mechanisms, include android aapt atlas-aapt.

QUESTION

How to properly connect to MongoDB using Cloud functions?

Asked 2022-Mar-25 at 16:08

I would like to connect to my Atlas cluster only once per instance running Cloud Functions.

Here is my code for an instance :

const MongoClient = require("mongodb").MongoClient;

const client = new MongoClient("myUrl", {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});

exports.myHttpMethod = functions.region("europe-west1").runWith({
  memory: "128MB",
  timeoutSeconds: 20,
}).https.onCall((data, context) => {
  console.log("Data is: ", data);
  client.connect(() => {
    const testCollection = client.db("myDB").collection("test");
    testCollection.insertOne(data);
  });
});

And i would like to avoid the client.connect() in each function call that seems to be really too much.

I would like to do something like this :

const MongoClient = require("mongodb").MongoClient;

const client = await MongoClient.connect("myUrl", {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});

const db = client.db("myDB");

exports.myHttpMethod = functions.region("europe-west1").runWith({
  memory: "128MB",
  timeoutSeconds: 20,
}).https.onCall((data, context) => {
  console.log("Data is: ", data);
  const testCollection = db.collection("test");
  testCollection.insertOne(data);
});

But i can't await like this.
In my AWS Lambda functions (running in python) i have not this issue and i am able to connect only once per instance, so i guess there is an equivalent but i don't know much JS / Node JS.

You can store your database client as a global variable. From the documentation,

Cloud Functions often recycles the execution environment of a previous invocation. If you declare a variable in global scope, its value can be reused in subsequent invocations without having to be recomputed.

Try refactoring the code as shown below:

import * as functions from "firebase-functions";

import { MongoClient } from "mongodb"; 

let client: MongoClient | null;

const getClient = async () => {
  if (!client) {
    const mClient = new MongoClient("[MONGODB_URI]", {});
    client = await mClient.connect();
    functions.logger.log("Connected to MongoDB");
  } else {
    functions.logger.log("Using existing MongoDB connection");
  }
  functions.logger.log("Returning client");
  return client;
};

export const helloWorld = functions.https.onRequest(
  async (request, response) => {
    const db = (await getClient()).db("[DATABASE]");
    const result = await db.collection("[COLLECTION]").findOne({});
    response.send("Hello from Firebase!");
  }
);

This should reuse the connection for that instance.
