So you created your first Twilio app and it became a hit, great! That’s no surprise with the magic of Twilio. But wait, since Twilio is so popular, why not deploy the app to a live site so that it can live on without you having to constantly run the app on your local computer?

Follow this tutorial to learn how to quickly deploy your functional Flask application to Amazon Web Services (AWS). Get ready to impress people with a live Twilio and Flask application on the web for free!

Tutorial Requirements

• A GitHub repository with files for your working Flask application. Make sure that the application that you want to deploy into AWS has secured required environment variables and is ready to deploy. You can refer to the Flask Application Tutorial if you need assistance starting a basic Flask app.
• Create a free account or sign in …

WebRTC (Web Real-Time Communication) empowers developers to build powerful voice and video communication solutions on web pages that work across browsers and devices. No plugins necessary. Whether you're building peer-to-peer video, content sharing, messaging, or chat tools, WebRTC makes coding easy and the end experience user-friendly.

Best of all, WebRTC is completely free. This open-source project provides the simple APIs needed to get audio and video communications working seamlessly on your web pages. Apple, Microsoft, Google, Mozilla, and Opera all support WebRTC's standardization across devices and browsers, so expect this new standard to stick around for the long haul.

If you're looking to use WebRTC APIs for your on-page communication solutions, we'll walk you through everything you need to know. First, we'll start with common use cases and benefits, and then we'll move on to how you can get started with WebRTC in little-to-no time.

What Is WebRTC used for? …

As many companies in the tech industry shift towards smaller, more independent microservices, tools like Kubernetes, Docker, and Helm are becoming essential in facilitating the development and deployment of these microservices.

While Kubernetes is used to manage available resources and orchestrate deployments, Helm is a tool that allows developers to coordinate the information sent to Kubernetes clusters. Helm runs on top of Kubernetes and outlines how an application will be structured.

Let’s take a closer look at Helm and its template files. You’ll want to install Helm first if you’d like to follow along and test Helm templating locally. If you have Homebrew, you can run the command brew install helm in your terminal. Otherwise, follow the Helm Installation tutorial.

Understanding Helm Charts

In general, Helm operates in a chart format. A chart is a collection of files in a directory that relate to some set of Kubernetes resources. …

A GPT-3 chatbot is a software application that is able to conduct a conversation with a human user through written or spoken language. The level of “intelligence” among chatbots varies greatly. While some chatbots have a fairly basic understanding of language, others employ sophisticated artificial intelligence (AI) and machine learning (ML) algorithms to achieve an almost human conversational level.

In this tutorial I’m going to show you how easy it is to build a chatbot for Twilio SMS using the OpenAI platform and the Flask framework for Python.

Want to have an idea of what the capabilities of GPT-3 are? Take a look at the following interaction I had with this bot using the project we are going to build in this tutorial:

Introduction to GPT-3

GPT-3 (Generative Pre-trained Transformer 3) is a highly advanced language model trained on a very large corpus of text. In spite of its internal …

There are quite a few cases in an application when you want to trigger notifications to users on database changes. One of the most common examples would be updates to feeds. When a new web feed arrives in your database you would want to send a notification to your users regarding this feed.

Usually, in an application, you might trigger an event after storing the feed in your database, which will asynchronously send a notification to your users. But is that the best solution available out there? Wouldn’t it be a lot better if you could send messages automatically when a document is created or updated in a collection, thus separating it from your business logic?

Recently, MongoDB Atlas released MongoDB functions as part of their new collaboration with Realm. These functions currently support modern JavaScript (ES6+) syntax and execute in a serverless manner. It is part of their …

Often referred to as a platform or programming language agnostic query language, GraphQL is a comprehensive approach to guide software engineers in building data-driven applications. It is, in my opinion, the new API standard, offering client applications the flexibility to request exact data and not an entire record from the database. If you are not yet conversant with this technology or looking for simplified technical content to guide you through, you are in the right place.

In this tutorial, you will learn some of the fundamental concepts required to build a Laravel API powered by GraphQL. This is a shift from the conventional architecture of building REST APIs, as we will take a different approach in this tutorial. To help us explore GraphQL, we will build a bookstore API with an ability to carry out CRUD ( Create, Read, Update, Delete ) operations on data, in your database.

Telemedicine is rapidly changing the healthcare industry. COVID-19 concerns aside, being able to see a doctor’s face without having to commute is a game changer.

Twilio Video allows developers to craft HIPAA-compliant telemedicine solutions that are fully under your control and tailored to your patients’ needs. Today I’ll show you how to make a telemedicine app using Twilio Video that lets you show a “virtual waiting room” where the patient can hang out until their doctor arrives. For the sake of simplicity, let’s build the front end in vanilla JS without a framework.

At a high level, here’s the steps we’ll be following:

• Set up a back end to control access to the application
• Set up basic front end scaffolding
• Build the provider experience
• Build the patient experience

For impatient types who want to skip straight to the code, the whole project is on GitHub.

Prerequisites

• A developer environment …

Surveys serve as a great tool for gathering information from a sample of people and can take multiple forms but are most common in the form of a questionnaire, either written, online or over the phone.

In this tutorial, I’m going to walk us through how to build an automated Phone Survey System which is a form of an Interactive voice response (IVR) system. An IVR system is a technology that allows a computer to interact with humans through the use of voice and DTMF tone input via the phone’s keypad. To build this application, I will be working with the Twilio Python Helper Library, the Flask framework for Python and Google Sheets. Below is a high-level overview of how the application works:

For the purpose of building this application, I have selected the following three questions to include in the survey:

1. Do you own or rent a house? …
