Currently IFC.js does not have a Vite React example (an alternative to Create React App). So, I made one based on the hello world repository.
First, download this project or clone the repository and install the dependencies with git clone https://github.com/IFCjs/hello-world. You can then install the dependencies using npm install and build all the examples with npm run build.
You can then execute the examples serving them locally with git run preview.
