            How do I set fire to a UIView in Swift?
            Asked 2021-Jun-15 at 11:32

            How do I produce an animation that simulates the burning effect of fire consuming an UIView from top to bottom in Swift?

            I found Fireworks, an app that allows users to tweak and try out different settings of CAEmitterLayer with instant results. The effects are great for applying to a whole screen but how would I use it for my purpose - where the UIView must disappear as the fire consumes it from one end to the other?

            Is there some tutorial on consuming UIViews with fire using the particle emitter anywhere? I know that I’m supposed to show some code but anything I put here would be irrelevant. I’ve also exhausted my search engine looking for something similar. That’s how I found the Fireworks app actually.

            This seems to be a use case that shouldn't be uncommon.

            I was once in your shoe before and came across this Open source library called particle animations.

            I would NOT recommend using the library itself since it's deprecated. But I would recommend referring to its source code to get an idea of how to use CAEmitterLayer and CAEmitterCell to make the looks of a Fire!

            As you could see from its readme, it has direct examples of Fire. It also states that even Apple and Facebook uses CAEmitterLayer and CAEmitterCell to produce the effect of a fire.

            Solution 1

            Make Sure "http://" is in your URL Address .

            1. change from localhost to your ip
            2. add http://

            Solution 2

            I 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

            Solution 3

            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

            event emitter emit in sequence or in parallel, and behaviour when they are async
            Asked 2021-Jun-13 at 19:58

            Consider the following code:

            ...

            ANSWER

            Answered 2021-Jun-13 at 18:47

            Internally, the EvenEmitter hold an array of listeners for each event type. When you emit an event type, the EvenEmitter just goes through it's array of listeners and execute it. Therefore, the listeners are executed in the order it was added by addListener or on method.

            To answer your questions there are two parts: a) it executes in the order you added the listener and b) it depends if the listeners are async or not. If your listeners are synchronous, then you can expect that behavior. If your listeners are async, you can't expect that. Even if your execute your async synchronously, they will not necessarily resolve at the same time because it's the nature of being async.

            I am new into RxJava and I was under the impression that for each event each subscriber is being notified. So if we have N subscribers and a stream of X events the onNext for each of the N subscribers would be called. But when I run the following code:

            RxJava sequences are synchronous by default thus the subscribe call above will run your emission code right there. To achieve the interleaving, you need a way to tell the source when both consumers are ready to receive. This can be done several ways:

            Prime ng table not updating on first change
            Asked 2021-Jun-08 at 11:21

            I have a prime-ng table of shops, where I can remove and add shops to a list.

            The behavior: When a shop is added, the ChildComponent emits an event to ParentComponent which then adds the shop to the list and updates the input observable of the ChildComponent so that the shop no longer appears in the table.

            The issue: The above behavior works fine except when the table is filtered, then when adding a shop the table is not updated even though I can see that the table array has been updated correctly in the component. However, when another shop is added (in the same filtered table) it works fine, and then both shops are removed from the table.

            The table is part of a pure component (child):

            I was studying the concept of promises in javascript and the states:pending/resolved/rejected. But I couldn't find much info out there on how the pending state changes to resolved/rejected. Does it happens through event emitters and listeners? If not how does that work?

            I won't do a better job explaining than the article I used to look into this a little while back but I think the term you're hunting for is executor.

            The function passed to new Promise is called the executor. When new Promise is created, the executor runs automatically. It contains the producing code which should eventually produce the result. In terms of the analogy above: the executor is the “singer”.

            Its arguments resolve and reject are callbacks provided by JavaScript itself. Our code is only inside the executor.

            When the executor obtains the result, be it soon or late, doesn’t matter, it should call one of these callbacks:

            resolve(value) — if the job is finished successfully, with result value. reject(error) — if an error has occurred, error is the error object. So to summarize: the executor runs automatically and attempts to perform a job. When it is finished with the attempt, it calls resolve if it was successful or reject if there was an error.

            Promise chaining unhandled promise
            Asked 2021-Jun-05 at 03:56

            I'm learning Node.js right now and practicing using EventEmitter along with promises.

            The successfulOrder function runs through both promises: verifyStockP and verifyCardP both promises are super simple.

            I noticed that when I purposely make one of the two promises reject, the program works as expected. The catch error code runs as expected.

            If I force both promises to fail, I get the following error message: '(node:2316) UnhandledPromiseRejectionWarning: card invalid;'

            How would I make it so we don't get this error if both the verifyStockP and verifyCardP promises reject?

            Thank you all in advance!
