react-component | some react components | Frontend Utils library

I'm having a little trouble understanding how Typescript infers props in JSX. The issues has come up in the following context -- I'm trying to make a component that accepts another component as a prop, e.g. (a simplified example):

I have a web template and a lot of javascript files for design. I want to use this files with React component. I put the javascript files to index.html but its not working.

There is a lot of classes in the html for design, for example:

I'am currently learning to code, and build a react-component with four charts, which are changing when the header is clicked. Everything is working fine, but the active header should have the className "open", which i have defined above in the styled-components. I tried to solve it with classList.add and classList.remove but it's not working. Thanks for your advice.

I'm creating some basic elements in Stencil for a custom design system. I created some basic components, which work fine on their own as custom elements, but throw errors when used as React components.

I generated the React components via Stencil by includng the @stencil/react-output-target in stencil.config.ts.

I've added styled-jsx to my Preact (set up with this TS template) project, and can style things inline via the

But if I extract that style into a separate css variable (either in the same file or externally) while following their instructions I get the following error:

I have to use a MUI5 DesktopDatePicker as shown in the manual here https://mui.com/components/pickers/#react-components.

Below is the code to set the "push" animation state with hooks plus an additional function I tried that didn't work:

I was getting the 'window is not defined' error when importing react-component-export-image so I used a dynamic import to get around that. I don't get that error anymore but now I get 'exportComponentAsPNG(componentRef) is not a function'. Is there a better way to deal with the 'window is not defined' error or a way to use the function I am importing dynamically? If not, is there a different npm library that works to generate an image from a react component?

I'm using react-headroom for this project and needed to edit its code so the
