QUESTION
i'm trying to use public publicRuntimeConfig inside a TypeScript plugin with no success. With JS plugins i have no problems. But now i'm really stuck, i think i don't look at the right place.
The question is how can i access to this config in a TypeScript plugin ?
Here's my nuxt.config.js:
...ANSWER
Answered 2021-Jun-15 at 20:42Nuxt makes the $config
available in two ways: as this.$config
on every component instance, and context.$config
passed to "special nuxt lifecycle areas like asyncData
, fetch
, plugins
, middleware
and nuxtServerInit
" (docs).
It looks like you need to access the $config
outside a component, so you'll need to retrieve it early in the request cycle. In particular, since you're mutating the Vue.prototype
, this feels like a good fit for a plugin in the Nuxt sense, which isn't quite what you've got in your code.
If you put your plugin file in the plugins
directory and reference it from the plugins
array in nuxt.config.js
(see link above for a broader example), you could rewrite it like this to access $config

QUESTION
I want to collect the names (Jenny, Tiffany, etc.) that are stored in every object. and these objects live in an array. I've used Array.prototype.every()
and Array.prototype.forEach()
, but I don't think they are the right methods.
I also want to note that majority of these codes are from Codaffection. I am practicing on developing in React.
If you would like to experiment with the code, click here.
In every object, there is an id, fullname, email and etc.
This is the code that adds, edits, generates unique ids for each employee, and gets all storage data.

QUESTION
Is there anyway to get the underlying div element on a @ViewChild
? I have tried to read the following of which none work:
ElementRef.prototype.nativeElement
-- returnsElementRef
HTMLDivElement
-- returnsundefined
ElementRef
-- returnsElementRef
I am trying to do this so I can do without having to call nativeElement
in every call to the content
property.
Here is what I am doing (replacing the read
with an item from the list above):
ANSWER
Answered 2021-Jun-15 at 16:24The common pattern is to use a setter if one more level of abstraction is needed between an ElementRef and its property.

QUESTION
This is my code:
...ANSWER
Answered 2021-Jun-15 at 12:20React is a framework that is state-based - the state informs the render of the DOM. Trying to use querySelector and its equivalent won't work like you think it will.
So here's an example of this working.
We set the state to be the index of the span (initially nothing).
handleClick
which is attached to thediv
(or would be attached to yourScale
element) grabs the data id attribute from the span and adds it to the state.This triggers the page to re-render, the spans get rebuilt, and depending on the state the
selected
class gets added.
There is no other DOM manipulation going on. React does all that heavy lifting for you.

Solution 2I faced same issue, it happens in Android, but works well in IOS. I guess this issue about Flipper Network.
For while, I commented
initializeFlipper(this, getReactNativeHost().getReactInstanceManager())
in this file
/android/app/src/main/java/com/{your_project}/MainApplication.java
Whoever is still struggling with this issue. it's happening because of Flipper network plugin. I disabled it and things work just fine.
My workaround to make this work is commenting out line number 43

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.

QUESTION
I am trying to wrap my mind around C++ 20 concept and constraint by porting some of my old code.
...ANSWER
Answered 2021-Jun-13 at 19:33A concept is not a type, so it can’t appear as a container element type—neither in the type of an object (this is why you have to use std::vector
to approximate std::vector
) nor in the type for your concept ContainerOf
. Moreover, you can’t use a concept as a template argument, so you can’t have a higher-order ContainerLike
concept.
What you can do is make a Container
concept that checks only for empty
, add the constraint
QUESTION
I am working on a terminal game. The game field is occupied with fieldCharacters (░) and holes (O)
The field is generated randomly but I also want to ensure that the pathCharacter (*) always lands in the top left of the field (which is made up of a set amount of arrays)
To do this I assigned the first index of the first array to pathCharacter (*). See code below:
...ANSWER
Answered 2021-Jun-14 at 10:47There's a number of things I'd fix.
- First, you really shouldn't add your own methods to
String.prototype
; that way lies madness if you want any sort of maintainability. - Second, your
print()
method can't work (it's referring to an implicit globalfield
to modify the instance field_field
) – not that you're using it anyway, though. - You should probably use an array of arrays instead of strings, for less awkward manipulation.
- You don't need a class for
Field
