Building a video on demand application using Gatsby and AWS

On-demand streaming platforms have become commonplace in the contemporary household. Powerful services like Netflix and Amazon Prime are just two examples of Over the Top (OTT) video platforms in the technology industry. Given the rapid growth of streaming services, now may be the right time for media companies to invest in building their own video on demand web application.

In this tutorial, we take a look at how to build a basic video on demand (VoD) web application by using Gatsby.js – a framework built on top of React – and Amazon Web Services (AWS). Then we will build the backend for the application using AWS Amplify, and test out the application by uploading a sample video via the AWS interface and testing it inside the application.

Understanding AWS

To build our video on demand project, we are going to use AWS and React as our stack.

Amazon Web Services (AWS) is a set of cloud-based services offered by Amazon, which can be utilized to build cloud-powered applications. They are super simple to set up, have awesome documentation (both by the creator and the community), and are reasonably priced as well. For beginners, you get $100 worth of free usage every year, which is more than enough for people who are just starting to learn how it works. AWS offers a vast variety of services, and it has a preset for almost every use case possible with a generic web application.

In this tutorial, we are going to use the Amplify microservice from AWS, which includes support for many other microservices internally like the S3, MediaConvert, and Cognito. Amplify provides a quick interface to help you get started with mobile and web applications quickly.

Using AWS and Gatsby with GraphQL

While AWS is the brains of our project, we still need a way to communicate with the user. This is where the frontend comes in. And, even though there is a normal convention to use server-side rendering to handle such use cases, server-based applications often take a hit in performance as well as offline capabilities. To account for this, we will use Gatsby and GraphQL with AWS.

Gatsby is a pre-rendering framework built on top of React. Gatsby allows you to pre-render your React code and takes the load off your users’ clients to render your application on the device. The offline plugin in Gatsby also converts your app into a full-fledged PWA with just one added line in the config file.

Important to our project, Gatsby also has awesome support for GraphQL, an open-source language used for data query and manipulation. GraphQL is a great alternative to the conventional REST framework and allows a great level of customization on how data is transmitted across the web. Gatsby uses GraphQL on its data level to boost performance.

Now that we have a basic understanding of our tech stack, let’s begin with the tutorial.

Getting started with a VoD application

Setting up the AWS backend requires a client available for testing; for our example, we will be using Gatsby.
