I am a front-end developer and uses JavaScript/PHP a lot. I would appreciate if someone could give me the solution and help me explain it (if not very time consuming).

I am removing some very intertwined global state from a new app (redux/sagas/selectors), to -> context api and react-query. There are tons of selectors integrated into this "global state", that is now needing to be refactored. I've only put a few, co-locating them with the mutations that generate the required data. BUT --

What are your strategies of using "selectors" with react-query?

Where are you locating these selectors, in the component folder or in a "selectors" folder, or sitting within the react-query useQuery in which the data is derived?

So, just to be clear, I am using the new react-query selector functionality. My legacy APP has selectors globally & in the components proper, and I am not sure that is the clearest way.. also, especially if I have a useQuery wrapper sitting globally... just trying to sort out the architecture here.

Any help is appreciated.

Note: I guess we could have a "selectors" file (co-located) with the feature, but do we then import the useQuery hook I have and just do it there.. in a "selectors.ts" file IN the feature folder it is used in..... OR move the selectors INTO the useQuery wrapper hook file.

1. What if these selectors are feature dependent (no other feature/part of the is gonna need them?).
2. What if these selectors can be used globally?

Strategies?

In the Pygsheet reference doc here it shows a wrap_strategy property.

I am doing a study on the feasibility of a Spring Batch composed of two datasources. A SQL datasource for the Spring Batch metadata and a MongoDB datasource (with transactional use) for the business data. The transactional aspect raises several questions here.

The following topic: Spring batch with MongoDB and transactions and related resources provide a number of answers to my questions. The answer mentions the use of Spring's JtaTransactionManager to manage distributed transactions on the two datasources. This technique uses the 2PC protocol. It is also the most robust solution if I understood correctly. https://www.infoworld.com/article/2077963/distributed-transactions-in-spring--with-and-without-xa.html?page=2

On the other hand, I found some resources about Spring's ChainedTransactionManager. This technique uses the best effort 1PC protocol. This solution is less robust, if I understand correctly the system can be in an inconsistent state in case of a problem in the infrastructure (network failure for example). The ChainedTransactionManager has the advantage of being easier to implement and offers better performance. I saw that it is deprecated https://github.com/spring-projects/spring-data-commons/issues/2232.

What are the concrete risks of using the ChainedTransactionManager in a Spring Batch? In case of an error, can I have inconsistencies between the Spring batch metadata and the business data in Mongo? I imagine there are also considerations to take into account with retry or chunk skip strategies?

Thanks a lot for your help.

So, I am making a query everything my context API is updated via a form selection update..

So, order of operation is like so.

1. User makes a change to a form by selecting (one of possible many) from dropdown.
2. Change updates "context api" which resaturates the parent component.
3. Because the form key/values changed, I fire a mutation.
4. Mutation returns a value. So far, great.
5. But, when I repeat step #1 - #4, another component flickers with that updated value because at some point the "const" that is expecting a value is undefined... THEN, it has a value..

So, like so..

has a value... ...query api call... has no value ...returns query has a value

I'm working on a project dealing with chess games. After some processing of the data I need to get the FEN (https://en.wikipedia.org/wiki/Forsyth%E2%80%93Edwards_Notation) notation of a particular position. I've already written the code for each piece FEN encoding, but I'm having a hard time encoding the character that represents the number of consecutive squares that are not occupied.

As an example, take the following FEN code:

I was trying to write my first ultra-simple numpy testcase, but the first thing I thought of seems to hit a roadblock.

So I did this:

I have a problem. I have a class with a function called getAgentStrategy. In that function I have the following code:

I am using Nuxt-Laravel-Sanctum.

While hosting on localhost for both api and client, login attempt is success and user response is getting back.

But, after uploading to server (api: api.repairtofix.com & client: admin-control.repairtofix.com) login seems to be success while user details is not getting back. I get error with 401 {message: "Unauthenticated."}

ie. It works on npm run dev, but after npm run generate it doesn't work
