I want to solve the following problem in js:
When the page refreshes, I have 1 entry file pulled up in html and after it has loaded, its chunks are pulled up. I would like to bypass this structure a bit and not wait for app.js to load, but load the chunks I need in parallel. Is it possible to do this if these chunks are assets of my entry app.js?
I am working with ReadableStreams in JS/Browser code and hit the following issue. When using a ReadableStreamBYOBReader to control the size of stream reads, if the stream is closed during a read request without enqueued data, the read never returns. See the first snippet below.
The last read returns as expected when ReadableStreamDefaultReader is used to read the stream. See the second snippet below (the stream implementations are identical in the snippets).
Given that this works the same in Chrome and FF, I’m assuming it expected behavior. But if so, how do you close a stream being read BYOD mode when you don’t know how much data is remaining until each read request is made? Raising an error closes the stream, but that’s rather ugly.
These snippets run in Chrome and FF, but not Safari because Safari doesn’t have the full stream API yet. Also, please ignore that byobRequest is not used and that reading isn’t optimized. My goal was to simplify the logic.
// Hangs if you try to read and the stream closes (when readBlocks > streamBlocks)
const readBlocks = 4;
const streamBlocks = 3;
const blockSize = 1024;
const stream = makeStream(streamBlocks);
const reader = stream.getReader({ mode: "byob" });
let buffer = new Uint8Array(blockSize * readBlocks);
readAllBYOB(reader, buffer).then(([blocks, done]) => {
reader.releaseLock();
let byteLen = 0;
for(const block of blocks) {
byteLen += block.byteLength;
}
console.log("all done, bytes read:", byteLen, done);
});

let totalBytesOutput = 0;
console.log("creating stream size:", loops * blockSize);

}OBS: I decided to open a answered question here because I have seen so many posts in Reddit and Github about submitting a form with shadcnui/react-hook-form in a Remix app.
I had an issue building a form with Remix and shadcn/ui (which uses react-hook-form) and I just solved it after hours.
To build the form, I followed these pages:
The problem was happening when I was submitting the form, not receiving any logs that I put in some sections of my code.
I checked other cases and tried some things to resolve it:
onSubmit attribute to various structuresfield values (from render attribute in my Switch component from shadcn, like that:<Switch
checked={field.value}
onCheckedChange={field.onChange}
name={field.name}
ref={field.ref}
disabled={field.disabled}
onBlur={field.onBlur}
/>
For a school project I’m searching an API who have “old” animation films, cartoons and manga tv shows to be played in French.
I already try TMDB but it doesn’t have what I’m looking for…
Can any one make that screen in React Native . In which there is Grid of 4×4 dice which get from list .
Also 4 Player who is playing that game , and also spectator (Viewer) can comment on the screen . I
I expected to get the screen below

Good morning everyone.
I have a project in Laravel in which I want to connect to a websocket of which I have the URI, the ClientToken and AccesToken. The problem I have is that I have tried several methods to use websockets in Laravel, but none of them works for me. I have the following code:
use WebSocketClient; class MewsWebSocket extends Controller { public function index() { $client = new Client("wss://ws.mews-demo.com/ws/connector?ClientToken=E0D439EE522F44368DC78E1BFB03710C-D24FB11DBE31D4621C4817E028D9E1D&AccessToken=C66EF7B239D24632943D115EDE9CB810-EA00F8FD8294692C940F6B5A8F9453D"); while (true) { $message = $client->receive(); echo “Message received: {$message}”; sleep(1); } } }
(There is no problem showing the tokens as they are public for the demo environment).
The problem I have is that I have copied the host and used it in another file that I have created in js to see if the URI works, and if I connect to the socket and receive messages, while with the PHP code does not.
const WebSocket = require('ws');
let ws = new WebSocket("wss://ws.mews-demo.com/ws/connector? ClientToken=E0D439EE522F44368DC78E1BFB03710C-D24FB11DBE31D4621C4817E028D9E1D&AccessToken=C66EF7B239D24632943D115EDE9CB810-EA00F8FD8294692C940F6B5A8F9453D");
ws.onmessage = function(ms) {
console.log(ms.data);
}
I wanted to know if anyone knows any way to use websockets in Laravel in the way I need it for my project.
I am working on a form that takes values and puts them in a spreadsheet. I want to take the values from that spreadsheet and use them as replacements in a sheet (with the intent of saving to .pdf, which I will learn next)
Here is a snippet of my code. I was expecting the values in the {{}} to be replaced with the values from the spreadsheet. It’s not happening though. It NAMES the document appropriately, but I think I’m using the wrong function call for the body.
function createNewGoogleDoc(){
const googleDocTemplate = DriveApp.getFileById('<myTemplateID>');
const destinationFolder = DriveApp.getFolderById('<myFolderID>');
const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Form Responses 1');
const rows = sheet.getDataRange().getValues()
rows.forEach(function(row,index){
if (index === 0) return; //using strict equality check to see if this is the header row. If so, pass.
if (row[38]) return;//38
const copy = googleDocTemplate.makeCopy(`${row[4]}`+''s Service Contract',destinationFolder);
const doc = DocumentApp.openById(copy.getId())
const body = doc.getBody().replaceText();
//const friendlyDate = new Date(row[31]).toLocaleDateString();
//const friendlyDate2 = new Date(row[32]).toLocaleDateString();
body.replaceText(`{{Email}}`, `${row[1]}`); <--- this here.

I am using an API from Aeris Weather Alerts and when there is no alerts for the area, the response is blank (“response”: []). Using the code below, is there a code I can use when the response is blank to have a default text that reads “No Weather Alerts”?
window.onload = () => {
const target = document.getElementById('alerts');
const aeris = new AerisWeather('CODE', 'PASSWORD');
const request = aeris.api().endpoint('alerts').place('SDZ047').filter('county').limit(3);
request.get().then((result) => {
const reports = result.data;
if (reports.length > 0) {
let html = '';
reports.forEach((details) => {
html += `
<div class="cardalert">
<div class="cardalert-body" style="background-color:#${details.details.color || '000000'};">
<div class="alertmessage">
<p><img class="iconalert" src="${details.details.color || 'N/A'}.gif"></p>
<p class="textalert">${details.details.name || ''}<br><span>Issued: ${aeris.utils.dates.format(new Date(details.timestamps.issued * 1000), 'MM/dd/yyyy h:mm a')} - Expires: ${aeris.utils.dates.format(new Date(details.timestamps.expires * 1000), 'MM/dd/yyyy h:mm a')}</span></font>
</div>
</div>
<br><p class="bodytext">${details.details.body}</p><br>
</div>
`;
});
target.innerHTML = html;
}
});
};
</script>
Nothing at this time besides putting a second layer with a text.
I’m reading Mathias and Meurer’s article JavaScript engine fundamentals: optimizing prototypes. The article says:
This
ValidityCellis invalidated whenever someone changes the associated prototype or any prototype above it.
I can’t understand why the cache was invalidated when the prototypes above were changed.
For example, given a prototype chain:
kitty ---> Cat.prototype ---> Animal.prototype ---> Object.prototype
And a method eat stored in Animal.prototype.eat.
If the code tries to retrieve a method kitty.eat(), why will its cache be invalidated when the Object.prototype is mutated, not when Cat.prototype is mutated?
kitty.eat(); // While executing, the engine makes an IC for Animal.prototype.eat
Object.prototype.x = 0; // Should not have any effect on the chain from kitty to Animal.prototype?
kitty.eat(); // But the cache is invalidated so we need to traverse the chain to find `eat` again?
I am working on an extension to search/edit images from a website. I am stuck and can’t find a package that lets me select an image on a website
The behavior I want goes like this:
Any help is appreciated, npm package, a repo or past experiences implementing such a thing.
I wrote an HTML, CSS, JS website that I would want to use on my phone whenever I feel like it. Is there a way to maybe download the whole project folder and open it on my phone like on my pc?
I read that opening the HTML file on a phone would cause some problems with images, script and styling.
How do I view my HTML webpage on my phone
I have below table :
.
.
.
<td >
<input type="text" class="car_color" >
<input type="hidden" class="number_car" name="my_timelist[times][]" value="0">
</td>
<td >
<input type="text" class="car_color" >
<input type="hidden" class="number_car" name="my_timelist[times][]" value="0">
</td>
<td >
<input type="text" class="car_color" >
<input type="hidden" class="number_car" name="my_timelist[times][]" value="0">
</td>
.
.
.
I want set value on input with class name class="number_car" by jquery with below code, But this effect on all inputs(have the class name). But I want effect value just on same td.
` $(‘.car_color’).change(function(){
let datetime = $(this).val();
$('.number_car').val( 123456);
});
`
How can I fix?
I used to run Vue “inside” Laravel project by writing .js, .vue files in resources/js folder of a Laravel project.
When I run website, browser (Chrome) did not refresh when clicking any link.
But when I split that project into Laravel and Vue seperately (with same packages) as follow:
project
|___backend
|___frontend
The browser refresh every time I click any link.
Additionally, website’s performance is down. It takes more time to load.
