ng-transition | Transition elements via classes | Frontend Framework library

I'm practicing Vue transition-group and imitating Vue document example specifically on THIS particular section.

The problem is that my example will apply animation only on end-element instead of element that's being Added/Removed.

Can someone please explain what I'm doing wrong? :( Thank you.

Here is link to the app for more clarification

I'm currently trying to find a way to display a custom component (like a Modal) to confirm route changes using the Prompt component.

The default behavior of the Promp component is to show a confirm dialog with a message, as you can see in this Example: React Router: Preventing Transitions.

Note: I am using the component.

The router has a prop named getUserConfirmation, which you can use to customize the behavior of the component.

Goal: prevent transitioning to another route if the current route's model has been changed (i.e. user has updated some fields but not saved, i.e. isDirty === true.

Setup: I'm using pretty much this exact code from EmberJS.com's Routing guide.

I'm making a simple todo list to learn Vue.

I am following this approach to add/remove an element from the list: Vue.js guide

When I remove an element from the array I would expect that element to disappear and then the other elements under it to take its space. But in my case the elements are shifted up and then the last element of the list (which has been "copied" one position up) is removed.

Problem: element removed correctly but transition wrong.

Reproducing problem: click remove on one of the items and look at the end of the list.

I tried persisting Saga Instances using RedisSagaRepository; I wanted to run Saga in load balancing setup, so I cannot use InMemorySagaRepository. However, after I switched, I noticed that some of the events published by Consumers were not getting processed by Saga. I checked the queue and did not see any messages.

What I noticed is it will likely occurs when the Consumer took little to no time to process command and publish event. This issue will not occur if I use InMemorySagaRepository or add Task.Delay() in Consumer.Consume()

Am I using it incorrectly?

Also, If I want to run Saga in load balancing setup, and if the Saga needs to send multiple commands of the same type using dictionary to track completeness (similar logic as in Handling transition to state for multiple events). When multiple Consumer publish events at the same time, would I have race condition if two Sagas are process two different events at the same time? In this case, would the Dictionary in State object will be set correctly?

The code is available here

SagaService.ConfigureSagaEndPoint() is where I switch between InMemorySagaRepository and RedisSagaRepository

In this example you can see some nice transition between pages triggered by the route change. (took from LevelUp Tutorials' React Animation course, thanks a lot Scott Tolinski).

Now I'd like to make these transitions happen in both directions, depending on which page it's transitioning to (and from), for instance:

• Page One -> Page Two (both pages transition from left to right)
• Page Three -> Page One (both pages transition from right to left)
• etc

From that first example I created this example where the value of x is dynamic and should be evaluated to either 100 or -100, based on the direction of the transition.

I haven't fundamentally understood how useTransition() works, and the documentation is rather limited. The examples look amazing but are quite hard to understand.

This example seems to do a similar thing to what I'm trying to achieve but the code feels like black magic: the y property of each object returned from rows.map() appears to be related to the y value on the functions assigned to enter and update properties because if I remove that I get the error: Cannot read property 'replace' of undefined. How does that work?

The React Router v4 component is perfect for the use case of protecting navigation away from a partially filled out form.

But what if we want to supply our own logic in place of the default browser alert() that this component uses? React is intended for creating UIs, so it seems like a pretty reasonable use case. Digging through the issues on Prompt in the github I did not find anyone asking about this.

Does anyone know of a solution for providing custom behavior for the alert?

I have a list of items, contained within a javascript array. Similar to the examples found on the vue.js documentation.

This is the workflow I'm struggling with:

• A user clicks "Add".
• I immediately add an item to the list (in the spot where they asked it to be)
• I send an ajax request to the server to create the item.
• The call returns with the database row for the new item.

I'm using the database primary key as my vue key - which I have no way of knowing up to the point the ajax call finally gets back to me. But if I simply update the ID on the object, I end up with that row transitioning out and then back in.

Is there a way to tell vue that I'm changing the ID of an item?

My ideal case would be something along the lines of:

I would like to prevent a react-router transition away from a form if it is invalid. Using a prompt to do this is unsatisfactory, as I want to totally block the user from navigating to a new route until the form is valid (whereas the prompt seems to always provide the user the option to proceed), and would like to display an error message on my page instead of an intrusive prompt.

How might I prevent this transition without a prompt?
