Build a Covid-19 Alert System with Vue, Node, SMS and Twilio SendGrid

One of the most important instruments in dealing with the spread of COVID-19 is having complete and accurate information about hygiene, the nature of the disease, and most importantly, the spread of the disease in different locations.

In this tutorial, you will learn how to use Twilio’s Programmable SMS and Twilio SendGrid to build a COVID-19 Alert Subscription System for providing accurate information to subscribed users.

Once finished, you will have developed a system that:

  • Allows users to subscribe to COVID-19 SMS and email alerts.
  • Allows an admin to broadcast COVID-19 updates to subscribers based on their selected location.
  • Sends SMS notifications to users in the subscribed area.
  • Sends email notifications to users in the subscribed area.

Project Requirements

In order to go through this tutorial, you will need the tools and technologies listed below:

  • Node.js installed on your system
  • Basic knowledge of JavaScript and Node.js
  • Basic knowledge of Vue.js
  • A Twilio Account (you can get started with one here)
  • A SendGrid Account (get started with a new account here)

Setting up the Backend Service

Express API Setup

To begin, you will need to set up the project for the application. Two sub-projects will be required in building the complete application: an Express.js project for the backend API, and a Vue.js project for the client-facing application.

Create a folder with the name covid-alerts at any preferred location on your system. This is the project folder that will hold the two sub-projects. Inside the folder, create a new folder named backend for the Express.js project.

In your command prompt, navigate to the root of the backend folder, and then run the following command to initialize the folder as a Node.js project:

npm init -y

The -y flag is added to skip the interactive process of the npm init command and instead, scaffold a barebones package.json file. You’ll also need the following packages:

  • express: The express package for conveniently creating Node.js APIs
  • body-parser: The standard Node.js body parsing middleware
  • cors: Node.js package for enabling and configuring CORS with various options
  • dotenv: To make use of environment variables
  • twilio: The Node.js package for working with the Twilio API for messaging
  • @sendgrid/mail: The Node.js package for working with the Twilio SendGrid Email API

You can install these all at once by running the following command at the root of the backend folder:

npm install express body-parser cors dotenv @sendgrid/mail

Data Scientist Creates Python Script To Track Available Slots For Covid Vaccinations

Bhavesh Bhatt, Data Scientist from Fractal Analytics posted that he has created a Python script that checks the available slots for Covid-19 vaccination centres from CoWIN API in India. He has also shared the GitHub link to the script.

The YouTube content creator posted, “Tracking available slots for Covid-19 Vaccination Centers in India on the CoWIN website can be a bit strenuous.” “I have created a Python script which checks the available slots for Covid-19 vaccination centres from CoWIN API in India. I also plan to add features in this script of booking a slot using the API directly,” he added.

We asked Bhatt how did the idea come to fruition, he said, “Registration for Covid vaccines for those above 18 started on 28th of April. When I was going through the CoWIN website – https://www.cowin.gov.in/home, I found it hard to navigate and find empty slots across different pin codes near my residence. On the site itself, I discovered public APIs shared by the government [https://apisetu.gov.in/public/marketplace/api/cowin] so I decided to play around with it and that’s how I came up with the script.”

Talking about the Python script, Bhatt mentioned that he used just 2 simple python libraries to create the Python script, which is datetime and requests. The first part of the code helps the end-user to discover a unique district_id. “Once he has the district_id, he has to input the data range for which he wants to check availability which is where the 2nd part of the script comes in handy,” Bhatt added.

8 Popular Websites That Use The Vue.JS Framework

In this article, we are going to list out the most popular websites using Vue JS as their frontend framework.

Vue JS is one of those elite progressive JavaScript frameworks that has huge demand in the web development industry. Many popular websites are developed using Vue in their frontend development because of its imperative features.

This framework was created by Evan You and still it is maintained by his private team members. Vue is of course an open-source framework which is based on MVVM concept (Model-view view-Model) and used extensively in building sublime user-interfaces and also considered a prime choice for developing single-page heavy applications.

Released in February 2014, Vue JS has gained 64,828 stars on Github, making it very popular in recent times.

Evan used Angular JS on many operations while working for Google and integrated many features in Vue to cover the flaws of Angular.

“I figured, what if I could just extract the part that I really liked about Angular and build something really lightweight." - Evan You

How Is TCS Helping With COVID-19 Testing In India

COVID-19 cases have only been on the rise. With the non-availability of effective drugs and vaccines, one of the effective ways to control it is to detect it early in patients. However, the task is easier said than done. While a large number of test kits are being produced, they are not enough to conduct testing in large numbers.

Government-run body, C-CAMP or Centre for Cellular and Molecular Platform, has been a key enabler in driving COVID-19 testing as it has been aggressively building, managing and scaling the ecosystem of MSMEs to produce test kits indigenously. However, they might not be enough.

System Databases in SQL Server

Introduction

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

  • Master
  • Model
  • MSDB
  • Tempdb
  • Resource
Master
  • This database contains all the System level Information in SQL Server. The Information in form of Meta data.
  • Because of this master database, we are able to access the SQL Server (On premise SQL Server)
Model
  • This database is used as a template for new databases.
  • Whenever a new database is created, initially a copy of model database is what created as new database.
MSDB
  • This database is where a service called SQL Server Agent stores its data.
  • SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.
TempDB
  • The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
  • User can create their own version of temporary tables and those are stored in Tempdb.
  • But this database is destroyed and recreated every time when we restart the instance of SQL Server.
Resource
  • The resource database is a hidden, read only database that holds the definitions of all system objects.
  • When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.
