Using context to store an array and try to array.map to generate a list of component, but the UI did not re-render to show all the component.

Program background:

I have a context which contain a array and the UI will have a "Add" button.

My Goal:

1. when user press "Add"
2. array in context will be pushed a new value in it
3. UI will be rerender and generate a new component

My problem:

I have try to use useState to store the array and that is completely OK since, once I update the list using setArray, that will triggle re-render and display a new component.

However, when I try to use useContext, the page will not be rerendered.

1. Should I still use useState to perform my goal? (then I have to manage 2 varible which are the context and state, I think that is a dummy way to work on it.)
2. is there any other method to achievel my goal?

I build multi-app Nuxt project, those apps don't communicate directly between them. Each app has own store and I want to use a directory for shared stores. I use this approach with components and that works fine.

I can do this without using createContext(), and useContext(). But I want to learn to use this, so I want to add useContext, and createContext.

Normaly i have this code in my MainScreen.js

I am writing simple JS app that shows weather. After first query variables like searchTerm or every variable from array are appends to the specific element. But after another query they are not override but added next to the previous one. How can i fix that? Should I use innerHTML or just refresh the page after another API call?

The code persistently Data stores in Firebase which is what I wanted after each session, but it's hacky because setOnes([...ones,1]) and writeToFirebase shouldn't be called under the same functions due to async, but every time I tried with useEffect(()=>writeToFirebase(),[setOnes]) to achieve similar result as ComponentDidUpdate, it got triggered right at the beginning of the launch and reset to FB database back to [1,1]. This is the code I have, codesandbox link: https://codesandbox.io/s/super-simple-react-firebase-functional-class-hook-set-up-eyo15?file=/src/App2.js:279-326

I'm making a simple task list that will take user input and append it to and unordered list whenever the add button is clicked. Once the item is added the text will be appended to a dynamically generated list element along with a delete button. It can add and and delete items just fine as long as the text is different. The issue is whenever multiple items with the same text are generated the list won't delete the specific item clicked, it will start from the bottom of the list and work its way up. How could I fix this issue?

I have started using NextJS and React recently.

I am trying to implement the multi page forms in my app, but I don't know how can I persist and pass the form data from one page to another page.

There are many guidelines about using state management libraries and context apis but they all are either in reactjs or defines the use between different components.

My _app.js looks like this:

when i review the stdout from running the script that calls webpack-dev-server IMO it is processing / emitting the scss | css OK. However the css is not included ( injected by dev server ) when you go to devtools and request "localhost: 8080" . Its as if the css does not exist.

Env: package.json

I've taken the Dapr pub/sub How-to sample and tried to update it to use RabbitMQ

I've downloaded the Docker rabbitmq:3 image from DockerHub and it should be listening on amqp://localhost:5672.

I have created a new component file for RabbitMQ called rabbitmq.yaml and placed it in the .dapr/components directory. My component configuration for RabbitMQ is:
