QUESTION
I actually have 2 components that require data from a reducer that has some state there. The CurrentWeather
component shows the weather at a very high level and the CurrentWeatherDetailed
in a detailed way. The first one is rendered first, and if clicked on Details it will render CurrentWeatherDetailed
. CurrentWeather
dispatches an action to fetch some data and update the state with that data, later it gets the state through useReducer and it renders the data from that state as expected. On the other hand, CurrentWeatherDetailed
, also tries to get the state that is currently populated, but it just returns null
(which is the initialState
) instead of what is actually in the state, considering that CurrentWeather
, I assume; has already changed the state. So I have tried a lot but I have not found an explanation of why this happens.
This is the reducer:
...ANSWER
Answered 2021-Jun-11 at 05:53The reason why this is happening is you are rendering only one component at a time and your components are siblings to each other. when your weather component fetches the data there is no weather details component
. So when you click on the details button you are mounting the CurrentWeatherDetailed meaning you are creating the component from scratch. At this point your CurrentWeatherDetailed
is not aware of what CurrentWeather
had done because components are isolated from each other and the only way of sharing information between them is via props . So your CurrentWeatherDetailed
initializes the reducer again.
You should move your useReducer to the App
and remove it from CurrentWeatherDetailed
and CurrentWeather
. So that you can share the information between the CurrentWeatherDetailed
and CurrentWeather
.

I'm trying to make a condition in the method clothing that if temperature is < 10 then advise particular clothes but I'm getting the following error:
The operator < is undefined for the argument type(s) String, int.
So how can I use this greater than >
and less than <
in the clothing method below?
ANSWER
Answered 2021-May-20 at 19:54In the line if( Tweather.temp() < 10 )
, Tweather.temp()
returns a String
. I would add another method that returns the actual minimum temperature as a double

QUESTION
The goal is to display different backgrounds depending on the fetched weather data. I'm trying to set the background inline in the JSX. On the first fetch, the data is populated but the background doesn't change until I click the search icon again. I've tried bundling both the fetch function and background handler function in one function then setting that function onClick and I've tried adding the backgroundHandler at the end of the fetch function. Both require an additional click after the initial fetch. On each occasion, you can see a 404 error on the initial fetch to populate the data. The photo I'm testing is imported into React as (cloudy).
Both Functions bundled into RenderUI Function
...ANSWER
Answered 2021-Apr-02 at 17:10Change backgroundHandler
to a useEffect
with currentWeather
as a dependency (just copy the function body and put inside it). useState
is async and may not be set yet when you run backgroundWeather
, that's why its blank
QUESTION
My JSX returns undefined even though the data is fetched immediately from the useEffect hook. I've tried nesting it within logical operators, console logging everything, I'm at a complete loss. I believe I'm traversing the Json correctly, so I don't understand why my data keeps returning undefined even though the data is clearly logged in the console.

QUESTION
My API url works in a browser, but for some reason all fields for the json object are returning as null. I have added the necessary internet permissions in the manifest, and am not sure why my objects are all null at the end of my api request. Here is my code:
...ANSWER
Answered 2021-Mar-31 at 20:07I found out the reason everything was showing null is that I was setting a breakpoint directly after the request function and not inside the listener itself. Therefore, the listener never heard the response yet when I arrived at my initial breakpoint. By setting my breakpoints inside the listener, a response had been heard, and the values were no longer empty.

QUESTION
Thanks in advance for any help you can give me. As mentioned in the title, I'm attempting to fight my way through an intro course and I'm struggling pretty hard with this particular issue.
HERE IS WHAT I NEED TO DO:
"Now we can start using APIs to get information from others applications. Lets create a Weather app like this one.
this project consist on create an app that takes the name of any city via input and display the current weather and the weather for the next 7 days.
The main point of this project is learn how to get info from the API and handle multiple promises.
You will get the input value (city name) from the element with the 'id=city' in the index.html file.
Each time the user clicks the 'search' button the program has to get the city name from the input (validation is required) and make the API call. Write all the javascript code in 'weather.js' file.
You need to create an account in OpenWeather and then you will be able to get an API KEY how to start with OpenWeather API
OpenWeather has differents API calls. You can see all the options here
We are using two of those:
All right first things first. You are going to create a re-useful fetch function to get data form the API
The first API call (current weather data) is getting a response with the current weather for an specific city name (lets use the option By city name). The response also contains the latitude (lat) and longitude (lon) things that you will need for the next API call."
HERE'S WHAT I'VE DONE:
...ANSWER
Answered 2021-Feb-11 at 21:53You say getWeather();
so you are passing no arguments.
function getWeather(url) {
assigns the first argument to url
, but since you didn't pass any that becomes undefined
.
Then you use that variable here xhr.open('GET', url);
which expects a string so it gets converted to "undefined"
which is a relative URL so is concatenated with the URL of the current page.
