I am trying to have a form on my react site that someone can fill out and it would add a new item in my list. I am trying to do this using "react-hook-form" which seems easy to setup and work with. It does capture the information when I console.log and check. I am trying to now add that to my array.

App.js (In this file I have the array withe objects along with my component I have passed in the props.

can't get the logout button to work properly. I'm using React and Firebase. Here is a portion of the code from App.js, where the function was declared

So I made a basic image slider in react that has a next and prev function to change slides manually. My issue is when I try to automate the slides using setTimeout, I run into issues.

Here is my code

guys I am just learning React and I decide to do try to build Hero Database and I encounter a problem.

When I click on any of Heroes, Bio state and Display state updates with data about the hero and modal window pop up with more information about him. But I don't know how to close it. I have Modal as a separate component and when I am trying calling the function (updateDisplay) from child component. which should set State of Display to False it just doesn't work :/

Heroes.js

I am learning the ropes of React and JavaScript. I started by grabbing a free template I found from GitHub. After creating a few other pages, I connected the app to a Django back end and created a model with two entries.

The objective is to be able to display the information from the model like title, objective, etc. I'm also new to using APIs to get this information, so I've been looking through various places online, but I just can't figure out how to fit in the code examples online with the code I have from the template from GitHub.

One of the places I've looked: https://reactjs.org/docs/faq-ajax.html

Below is Hero.js. This is routed to the home page and it's just what the template provider named it. The code example provided above and in many other places I've looked puts all their code in App.js. I know they're just doing that for demonstration purposes, but I'm not sure how to fit it into the template code.

I'm trying to post data to my database. I have two problems. Problem 1: I get a response that method is not allowed. I've put the images below

The second problems I have is that my data keeps returning null when trying to insert the user's comments into MySQL database:

Here's the error: [enter image description here][2]

Here's my code:

Hi guys very simple question. I have a home page and a room page. The question is why is the logo image in the navbar component loading in the homepage but not in the room page?

The home page is as follows:

I'm relatively new to ReactJS and just started to make a portfolio project.
When I run the program, it doesn't show any error in the editor but shows the following error in the browser.

Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of HomePage.

Here is my HomePage.js

I have a site built with React Static that has a Header component that is always present. Depending on if the current page has a hero component or not, the Header should be either light or dark.

The Header is rendered outside of the routes and the useEffect is triggered before the children is rendered. This is probably because of the routing.

This is the current code:
