Add Component into existing components

I have created my own Component that I wanted to integrate in the existing Card.jsx component
<myComp /> like this. I have Imported the Component and added it but for some reason the component is not visible! Is there any special procedure I need to follow in this app to add my own components?

Also what I noticed is I can't take for example existing components like ListAdder and add it in the Header for example, I import it correctly and add the jsx tag where I want the component to show up but nothing happens. So is in this app some special procedure to follow for adding and moving components around? Thanks

React components must start with a capital letter. I'm guessing that's what is causing your first problem. There's no special procedure. I tried importing ListAdder to the Header file and it worked fine. Maybe you didn't get import syntax correct?

import ListAdder from "../ListAdder/ListAdder";

I have simlar problem, I have created my own component and if the component is simple with only one <h1></h1> it works, but when I add an more complicated component where I use state and componentDidMount I get only white screen and the dev site works only when I delete the component again. Now I'm not very familiar with redux, can it be I need to register there something from my own component to get it working?

Look at the error message in dev-tools to see what went wrong. You don't have to hook up a component to redux if you're not using any state from the redux store.

I have tested now and I can't get it working, here the component that does not work in React-Kanban.

If you replace async await with something else it'll work. Babel handles async keyword in pretty complicated way, and the repo is currently not set up to handle it.

Do you know someone who maybe has time to make this repo so it can handle async await? Best case would be of course you. texxxo@gmail.com

The easiest way for you to do it is to add @babel/polyfill to the repo.

1. npm install @babel/polyfill
2. Import it at the top of the client.jsx file like this

import "@babel/polyfill";
import React from "react";
...

Thank you so much it is working now!
