vigilant | a security controller for Kubernetes | Model View Controller library

I'm trying to create a hamburger menu within React using state and onClick, from scratch. I have no experience with React Hooks so am trying to avoid that. The solution I have right now works, but is slow and glitchy and I have a feeling the code is quite flawed.

I deployed it anyways to test it out in live, and it's not working well at all in mobile chrome browser (https://vigilant-leavitt-a88a0e.netlify.app/). (though at least the background-color works when inspecting on a browser at mobile dimensions).

Can anyone tell me what I'm doing wrong here, or how this could be cleaned up? I have app.js feeding props to header.js.

Thank you!

App.js

I have this react component which every time it's rendered show the country information that receives via props (country) and using the weather stack API must show also the capital weather at the current time. The first part (displaying the country data that comes from the props) works fine but I'm struggling to get the data from the weather API. I see on console that I'm getting the current weather but can't assign it to weather variable using setState() therefore my app crashes.

This is the component code I have so far, I've tried using async/await and .then synataxis in case I was mispelling something but always I get the same result:

I create simple form on functional component ReactJS, with using Formik. Input fields my form should get data from API, when component mount. For this i'm using fetch and useEffect. After fetching, data from the API is retrieved but not filled until formik.handleChange is triggered.

If try to specify something in any input field, formik.handleChange is triggered, and all fields are immediately filled with data from the API (in my case, sould filled only email)

How i can triggered formik.handleChange when component will mount ?

I am currently developing a single page application using CRA. I am attempting to create a hero image that lives at the top of the application and contains an overlay. For the hero image, I am using a background image. The issue I am running into is maintaining the overall responsiveness of the background image. I would like the user to be able to see the entire background image regardless of the screen size.

I have a problem that i can't achieve. I wanted the user not to be allowed to write something on the input. I want them to choose from the calendar icon. My problem is that i user can write something on the input. I have achieved it using DatePicker instead of KeyboardDatePicker` BUT i also want the datepicker icon to show.

In short, i want to achieve the ff:

1. Don't allow user to write on the input.
2. Display datepicker icon
3. They should be able to click anywhere within the input
