Private component - for codes

I need a private component where I can upload the codes. It must be possible to upload HTML code. But I’m also thinking about the code structures used in the React platform. As you know, ‘React’ uses JavaScript (or TypeScript). Code in React Native is usually stored in .js or .jsx files, but there is also .css, .scss and .less. Don’t ask me why I need this if there is a PragmaFlow component. It’s really good, but can it be improved? Don’t ask why I don’t just develop with React. The next project will be there, I want to symbolically release something here in Adalao, and I want to show myself and others that you can do something quite good here.
