CurrentWeather | Software Engineering project

I got into Jetpack compose and I am having a hard time finding examples of a normal screen. Everyone just uses scaffold and calls it a day. Using fillMaxSize is supposed to do exactly this, can someone explain how composable inherit their size? The topmost composable specifically (root composable)?

This will be my first post here, so I'll probably be vague. I'm trying to get the data via node.js request and then pass them to another js file so that the appropriate html file can use them. Folder with this app looks like below:

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?

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

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.

Console of Data

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:

I try to create Room database and insert values to it, but I got this error:

It's long, but it's repeated the same sentence "Cannot figure out how to save this field into database. You can consider adding a type converter for it." What should I do? Here is my code:

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:

• Current weather data
• One Call API

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:

I'm making a weather app in React and I'm having problems accessing an array inside an object in state. Here is my code:
