The emergence of cloud computing platforms has transformed how data is managed, processed, and shared. Cloud computing enables the use of a remote server or network to store, manage, or process data, making it accessible from anywhere. This tutorial combines Contentful, CodeSandbox, and Netlify to build a full-stack application in the browser without setting up a server, database, or local development environment. It uses these tools to create a React app that displays content created on Contentful, showcasing how to combine these platforms to streamline web development and deployment processes. The tutorial covers setting up Contentful, creating content types and entries, installing dependencies, fetching data from Contentful using the JavaScript Client Library, rendering components, and deploying the application to Netlify or GitHub.
