app.js | A framework for js apps with top menu , toolbar and windows

I've been struggling with this all over my react-native app, so I set up a very simple example of it in codesandbox which you can view here:

https://codesandbox.io/s/elastic-star-5754q?file=/src/App.js

Within the View with the green background, all of the internal views are centered horizontally within their respective spaces as I would expect thanks to the "alignItems: center" style property. I would expect that I could also center them vertically within their spaces by setting "justifyContent: center", but that doesn't seem to work for me.

Am I fundamentally misunderstanding something?

I am building an app following the Rest Countries API challenge from frontendmentor (https://www.frontendmentor.io/challenges/rest-countries-api-with-color-theme-switcher-5cacc469fec04111f7b848ca). I have run into a problem. When clicking on the router link in countryDetail.js, the url changes but the component doesn't get re-rendered unless the page is refreshed.

I've read a number of questions on this same error but couldn't understand whats happening in my case. On the other questions this error is caused by an object being used as a React child or caused by more than one prop attribute being passed.

I'm trying to set formik and yup to validate a Day Field according to a Month Field, both using react-select, in such way that if the month is February then the max day allowed is 29. Just that...

I've managed to reproduce the error in a Codesandbox: https://codesandbox.io/s/formik-yup-reactselect-rmd9f?file=/src/App.js

If you select the Day 29 and any month, then it works, but if you select day 30 and February then this error appears and I can't find out what's wrong:

Uncaught Error: Objects are not valid as a React child (found: object with keys {value}). If you meant to render a collection of children, use an array instead.

The code is:

My intention is to get the weather data for the selected country, passing selectedCountry.capital to the query, so it is displayed the weather from current country capital when the data of a country is displayed.

The problem is my code tries to render the weather data before the weather array is fetched, resulting in an error.

TypeError: Cannot read property 'temperature' of undefined

I get the array data

I'm trying to implement authentication using XSUAA. I can able login with my SAP CF credential and login is working fine. The problem is with logout.

When I try to logout, it gets redirect to the logout page but the session is not cleared. After logout when I try to hit the url, instead of login page, it's redirecting to the index page.

I followed the official document Authentication check with Node.js and AppRouter but still I'm unable to fix this issue.

These are my configuration files.

manifest.yml

I have an application using ASP.NET Core MVC and an Angular UI framework.

I can run the application in IIS Express Development Environment without issue. When I switch to the IIS Express Production environment or deploy to an IIS host, my index referenced files cannot be read showing a browser error:

Uncaught SyntaxError: Unexpected token '<'

These pages look like they are loading the index page as opposed to the .js or .css files.

Here is a snippet of the underlying runtime.js as it should be loaded into browser, it is not loaded with index.html.

I developed an app in german (de-DE) and in order to translate the captions, I added the TranslationFile feature in my app.json.

This generates a translation file, where the source-language is "en-US":

Not thinking much about it, I changed the source-language to "de-DE" since my captions are in german and I want them to be translated to english.

Hence:

The problem that I now have, is that when I publish my extension and switch between english and german as my language in business central, all I get are the english captions.
