Script to use Chat-GPT at scale

We wanted to get categories for products just by product name. So instead of training our own AI model we tried chat GPT and are very happy with the results.

The question we asked chat-gpt:

I am creating a search feature for an ecommerce store. Create categories and tags for the product. Also, create a few keywords that users search for products in the category this product belongs to. product: Samsung Galaxy A53 5G

Response from ChatGPT:

Now how do we do this for 1000 products or maybe more?

We will need an API key from open ai and can write a script to get this done.

Go to this page and get the API key: https://platform.openai.com/account/api-keys

Code:

import { ChatGPTAPI } from 'chatgpt'

async function example() {
  const api = new ChatGPTAPI({
    apiKey: `PUT api here`
  })

  let questions=[`I am creating a search feature for an ecommerce store. Create categories and tags for the product. Also, create a few keywords that users search for products in the category this product belongs to. product: Samsung Galaxy A53 5G`]


  for (let index = 0; index < questions.length; index++) {
    const question = questions[index];

    const res = await api.sendMessage(question)
    console.log(res.text)
  }
}

example()

Above code will get results for all questions in an array and log responses.

Automation in google sheet using Apps Script

Automation in google sheet using Apps Script

We had a requirement to send an SMS to a patient when there is an entry for an appointment for them in google Sheets.

Sample data:

Link for sample sheet:

Google Sheets: Sign-in

Step 1: Add button in google sheet

Insert -> Drawing

Step 2: Create a custom function that can be triggered on click on the button

Extensions -> Apps Script

Step 3: Code to send SMS for appointments

function myFunction() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('appoinments');
ja
  // 2 dimentional array for sheets data
  var data = sheet.getDataRange().getValues();
  var timeZone = Session.getScriptTimeZone()


  for (var i = 1; i < data.length; i++) {

    // condition to send message to whome we have not already sent message and first column is not blank
    if (data[i][4] != "done" && data[i][0] != "") {
      var date = Utilities.formatDate(data[i][2], timeZone, 'dd-MM-yyyy')
      var time = Utilities.formatDate(data[i][3], timeZone, 'h:mm a')
      var name = data[i][0]
      var phonenumber = data[i][1]

      Logger.log("date: "+date)
      Logger.log("time: "+time)
      Logger.log("name: "+ name)
      Logger.log("phonenumber: "+phonenumber)

      // API to send SMS(Any provider)
      // Hit api to send sms
      // var url = `Put your sms provider url here`

      // var response = UrlFetchApp.fetch(url);
      // var json = response.getContentText();

      // set status to done, so we dont send messages again for same appoinments
      sheet.getRange(i + 1, 5).setValue('done')
    }
  }
}

Step: run and give permissions

Click on Advance on the bottom left :

Click on, go to the untitled project

Click on allow:

We can see logs as expected:

Now we can see the status column set to “done”

Step: Attach the function to button

Click on the button > assign a script > write the name of the function which we just made

Now add new appointments to the sheet and keep the appointment status blank. When we click on send message button, an SMS will be sent and the status will be updated in the sheet.

Share this with anybody you think would benefit from this. Have any suggestions or questions? Feel free to message me on LinkedIn.

Tech for Empowering Chingari’s Video Content Creators with Blockchain

Chingari’s 50-member tech team formed over a couple of years built the first social media platform that rewards its Content Creators and Users for earning passive income through Crypto.

Gari service and Transaction Sync service are the primary services responsible for blockchain integration.

High-level Architecture for Blockchain integration:

Gari Service’s role is to integrate with blockchain for the following features:

Create wallet and wallet management
Support internal transactions(App to App)
Support external transactions(Exchange to App and vice versa)
Give Airdrops and Rewards

Transaction Sync service’s role is to sync Gari service with Blockchain.

High-level Tech stack:

Node js (Nest js)
AWS Aurora (Postgres)
AWS SQS
Kubernetes

Scale:

As of Feb 2023, below are the stats:

Active wallets 24,13,500+
100k+ active daily miners
number of transactions per month ~ 15,00,000

Different flows:

Our eventually consistent system is achieved using distributed transactions across multiple services using SQS and Sync service.

Create wallet flow:

“Create wallet” is initiated from Mobile applications by generating keypairs using Solana SDK. Gari service accepts these new keypairs, maps them to a particular user by storing the public key in Database, and sends transactions for creating a wallet to the blockchain.

TransactionSync service keeps checking the status of pending transactions and updates them to success or failure. 100 percent sync is guaranteed for all transactions by TransactionSync service.

Transaction Flow:

High-level frontend to backend flow for a transaction:

Frontend: Transaction object is made on the frontend(Mobile applications) using Solana SDK, partially signed by user’s private key(Only known to the frontend), encoded, and sent to gari service.

Backend: Decodes transaction back to transaction object, validates the transaction, partially signs with Chingaris main wallet(Since Chingari is the fee payer), and sends it to the blockchain. TransactionSync service keeps checking the status of pending transactions and updates them to success or failure.

Transaction Backend flow chart:

Flow Between different Services:

Airdrop flow:

Airdrops are given to users by different services of Chingari for various modules. The rewards list is synced by the Gari sync service to its Database and then processed in a scalable asynchronous manner.

Using distributed transactions across multiple services using SQS and Sync service, Chingari is able to support stable wallet management and transactions for its users!
