If you encounter a Cannot find namespace 'JSX' error when using angular-instantsearch as a dependency, you can generally solve it by installing the necessary@types/package.
You can run the following command in your terminal:
npm install --save-dev @types/react
The issue is encountered primarily because these are shared UI components between React and Angular InstantSearch, so the dependency is assuming that certain types packages are already installed for developers using Angular.
