dnd 5e – How does the war launcher feat interact with a feature of hydra reactive heads?

The War Caster feat gives it the following property:

When the movement of a hostile creature causes an attack of opportunity from you, you can use your reaction to cast a spell on the creature, instead of making an attack of opportunity. The spell must have a casting time of 1 action and must target only that creature.

A Hydra has the following feature:

Reactive heads For each head that the hydra has beyond one, it gets an additional reaction that can be used only for attacks of opportunity.

Let's say that, for some reason, someone provokes an opportunity attack from a War Pit Hydra (possible, for example, a Wizard of the War Pitter who launches a Change of Change to become a Hydra) … what happens ?

1) The War Caster Hydra can use all their heads for opportunity attacks, or just one head for an eligible spell

2) The War Caster Hydra can use all their heads for opportunity attacks and / or eligible spells

I suspect that the correct answer is 1), but it is better to verify.

multisite: How to run the reactive application and the WordPress and React application without a head on the same server (managed by plesk)?

0

I'm pretty new on the website and on the server and I have a question:

I have a reaction app and it should be the main and only website I want to get to at www.example.com, and I want to use WordPress simply without a head (wp db and wordpress REST API) but on the same server. The server is managed by Plesk.

From what I understood, WordPress has to be installed in the root of my server documents, for example. / httpdocs /.

But when I want to get to my reaction application in www.example.com, I have to implement the contents of the compilation folder also in / httpdocs /, which interferes with wordpress. In this case, if I go to www.example.com, I get the wordpress site.

When I have my reaction application in another folder, for example. / github / build /, and set this folder as the root of my document, you can access the page in www.example.com, but you can not access wordpress (you can not find www.example.com/wp-login. php).

The only ugly way I think it can work is if I implement the compilation folder in the wordpress root directory, but the reaction app is only accessible at www.example.com/build (only riddles).

Is there any way to make it work as desired?

reactjs – How to print a reactive bar code component

I'm trying to print a bar code created by reaccion-barcode.

I have tried using the methods described in this question, but it seems that I can not print the barcodes.

Probably this is because an SVG is being processed by reaction-ship. I have also tried to react to print and react easily, but it seems that they also fail me.

I also hope to download the barcode but nothing seems to work.

architecture – When should I use the reactive web framework?

When I build a standard web API in the Java world, there are two ways to do it today.

  1. Use SpringMVC (non-reactive)
  2. Use SpringWebFlux (reactive)

There are few benefits of using Reagent that I can think

  • Uses fewer memory resources, since there are fewer threads running (perhaps better for a container-based implementation)
  • It is better for situations in which your api might need to call other apis and does not want to think about the concurrency problem (this can also be done in traditional webmvc, but then you need to use CompletobleFuturo etc while in reagent let the framework handle it)

There are some disadvantages that occur to me when using Reagent

  • The complexity of the code, since everything is now chained and you must be careful not to block the thread and you must be aware that there is no ThreadLocal like things like registration using MDC is more complicated now
  • Increase latency as there are fewer threads now

One of the selling points of the reactive way of doing things is the back pressure concept, but when the normal request / response is reached in the web pages, it is not used, whether you process it or not, there is not a process in the chain that reduces the production of data.

I'm not sure if the benefit I mentioned above is worth the complexity of a web apis. I would like to hear thoughts about that. If web pages are not the right place to use reagents, where do you think is the right place to use them? Or if the reactive form is the way to do it, then does not mean that there is no longer any place for the traditional way of doing things in the webmvc?
