kandi X-RAY | slik Summary
Slik uses requestAnimationFrame to tween values over time. You can give it a single value, an array, or an object. Internally Slik converts these values to ImmutableJS ones, and returns the tweened values as ImmutableJS objects (unless only a single value is supplied). Slik uses ImmutableJS so that when used with React you can keep your components pure (preventing updates if values have not changed) as ImmutableJS returns a new reference when updated, allowing quick checks for changes using PureRenderMixin for example.

QUESTION
I am trying to convert my vue app to nuxt app. In my vue app I used vue-slick-corousel with ease. But the same code with necessary modifications for nuxt, the corousel is not working on refresh. If I edit the template real time or navigate the app without refreshing the page, it works perfectly on second time visiting the page(s). Here is how I used vue-slick-corousel in my nuxt app
...ANSWER
Answered 2021-Jun-07 at 22:57EDIT: here is an explanation of the usage of $fetchState.pending helper.
fetch()is a non-blocking hook that will allow you to fetch data upon page/component loadingasyncData()is blocking but only when you navigate and not on initial render which can be annoying- you can make a blocking navigation with a combo of
fetch()anda middleware - using skeletons is a nice way of having the user wait while feeling that the app is loading (Facebook-y)
- your template is actually synchronous and will not wait for you to gather data, it is expecting to already have it right away.
VueSlickCarouselis actually waiting for you to provide it an array of items. But upon initial render and before have fetched any data, you only do havecategories: []as setup indata() $fetchState.pendingis a handy helper that can tell us when the whole calls infetch()are done. So if you will call 4 different APIs, it will equal tofalseonly when all of the 4 calls will be done.- you can actually set it manually too with
this.$fetchState.pending = truebut this is forcing it and should be used when understood properly.
- you can actually set it manually too with
- by writting
, we do basically say wait until all of my things intofetch()to be done before mounting this component at all. This prevents any.lengthmethod issues because the component itself is not mounted until there is something to apply.lengthon.
Here is a small image of Nuxt's lifecycle, focused on fetch() hook.
You should not mix async/await and then. Try to only use one of them (I do recommend the first one).

I need to remove the DC part of a signal. To do this I have this code:
...ANSWER
Answered 2021-Feb-09 at 14:19Another way to frame your problem is like this: You have data in 2 dimensions. Lets call the first one 'row' and the second 'columns' (this is standard vocabulary, but in your application they are probably 'time' and 'channel'). You have 31250 rows and 5 columns. You want to compute the mean for each column, giving you a vector of 5 values. Then, for each of the 31250 rows, you want to remove the 5 mean values. Lets do this!

I'm building a web scraper that logs into an authenticated webpage, navigates to a table, and scrapes this table every minute. The table on the webpage updates automatically with new entries. Here's how the webpage looks like:

QUESTION
I am making a code where the user can press one of five buttons, which get disabled after the click. Then it's supposed to count each press and store it in firestore database, and the number be shown on the button. I have not quite managed the counting yet (tried firestore increment), but that's for another question. I am relativity new to javascript, but I managed to display the number of votes, but the code is way too long and inefficient. This is my code for the buttons:

QUESTION
I have currently made a code to add data to my firestore database, which I thought worked well until I tested it today. I have made a modal to add the data and each time I add a new item, the number of times it is added goes up. So the first time it's only added once, but the item after that is added twice and so on. I am relatively new to firebase and js so I can't figure out what is wrong. Here is my code:
This is the modal I have for input:
...ANSWER
Answered 2020-Apr-08 at 01:43You're adding a new event listener to the submit button, each time you call addElementApparat.
- So the first time you call
addElementApparatyou add the first listener, so when the user then clicks the submit button, it adds a single document. - The next time you call
addElementApparat, you add a second listener. So when the user then clicks the submit button, the same listener gets called twice, and two documents are added.
The possible solutions are to:
- Either only add a listener once.
- Remove the listener when it's no longer needed.
The simplest change from your current code is to remove the listener once the user has clicked the submit button. An example for one of them:

Install slik
Require slik in the file where you'll be animating. Setup the values you want to animate. These values can be contained in objects, arrays, or simply be single values. If you're animating a lot of values I'd highly recommend using objects as it makes it easier to refer to your values later. Note: these can be nested values. Initial options: You can pass most of your config in here if you like, or add them using the methods with matching names.
Require slik in the file where you'll be animating. import Slik from 'slik';
Setup the values you want to animate. These values can be contained in objects, arrays, or simply be single values. If you're animating a lot of values I'd highly recommend using objects as it makes it easier to refer to your values later. Note: these can be nested values. const initialValues = { headRotation: 0, leftArm: { upper: 0, lower: 0 } };
Create an Animation.
Initial options: You can pass most of your config in here if you like, or add them using the methods with matching names. const animation = new Slik.Animation({ from: initialValues, to: nextValues // Defaults below // duration: 500 (milliseconds) // delay: 0 (milliseconds) // fps: 120 (frames per second) I would not recommend changing the frame rate // ease: Slik.Easing.Linear // loop: false });
Using methods: Note: fluent API returns the same object for each method (except the playing method which returns a boolean). More info below. const animation = new Slik.Animation() .from(initialValues) .to(nextValues) .duration(1000) .delay(2000) .ease(Slik.Easing.EaseInOutSine) .loop(true);
Handle changes in values. Bind a callback to the update event & update your component or redraw your canvas.
Canvas example animation.bind('update', function (values) { canvas.render(values); });
React example componentWillMount () { animation.bind('update', function (values) { this.setState({ values: values }); }); }
