This can be particularly useful if you have a software application with multiple frontends for different user groups, such as a user interface and a back office/administration interface.

However, by creating a web component from a part of your React app, you can easily reuse that component in other parts of your application.

Why is this article special? This tutorial is end-to-end and also covers how to actually build your Web Component using Webpack. Also, you get an idea of how to structure your code in an existing codebase.

1. Set up a React project (optional)

To begin, you will need to set up a React project. If you do not already have one, you can use the create-react-app (CRA) tool to bootstrap a new TypeScript React project…
