Below is a Javascript code which attempts to parse some protobuf input data.
'use strict';
import protobuf from 'protobufjs';
const proto = protobuf.loadSync('gtfs-realtime.proto');
const FeedMessage = proto.lookupType('transit_realtime.FeedMessage');
// sources is an array of Buffer containing the binary input
// const inputs = sources.map(FeedMessage.decode.bind(FeedMessage)); // this line does not work
const inputs = sources.map(x => FeedMessage.decode(x));
console.log(inputs[0].toJSON());
Why isn’t FeedMessage.decode.bind(FeedMessage) equivalent to x => FeedMessage.decode(x)?
I’m trying to create a game on pixi.js and implement custom physics for the Hero instance. I’m stuck on a jump down right now. My problem is that the collision should disappear with “state === jump”, but the Pixi.update method logically changes state === fall and when i have fall does not occur. if you remove the “if (this.#speed.speed > 0 && this.is Jump())” everything works, but I can’t figure out how to get the collision back so that the character jumps down only one platform.
I tried to enter an additional state of jumping down. I also tried using setTimeout (this leads to a memory leak) and a timer via a variable, but in this case there will be bugs when jumping in place.
I will attach a link to the github, as well as to the problematic parts of the code.
Thanks!

Code:
Hero instance
update() {
this.#speed.speedX = this.#movement.x * this.#speed.maxSpeed;
this.x += this.#speed.speedX;
if (this.#speed.speedY > 0 && this.isJump()) {
console.log('down');
this.#stateHero = $STATESCHARTER.fall
}
this.#speed.speedY += this.#gravity.gravityForce
this.y += this.#speed.speedY
}
stay() {
this.#stateHero = $STATESCHARTER.stay
this.#speed.speedY = 0
}
jump() {
if (this.#stateHero === $STATESCHARTER.jump || this.#stateHero === $STATESCHARTER.fall) return
this.#stateHero = $STATESCHARTER.jump
this.#speed.speedY -= this.#gravity.jumpForce
}
jumpDown() {
console.log('jump down')
this.#stateHero = $STATESCHARTER.jump
console.log(this.isJump())
}

I am really not good at writing regex so I took help from ChatGPT but whatever he is providing does not work. So I think I need an expert’s help for my case. So here I am expecting a solution from you guys.
So let me briefly explain my situation. I have a markdown js library that converts urls to html. But it doesnt support urls with format google.com and www.google.com because these two formats doesnt have the protocol. So basically, I need to identify these two url formats with regex, and then replace them with something like https://google.com and https://www.google.com so that the library can convert to html links.
The regex provided by ChatGPT is either matching the domain part of lets say [email protected] or doesnt identify nothing at all or if the url is wrapped with quotes or parentheses or brackets, it identifies them as well like "google.com". Or sometimes it matches the first part before @ in email addresses.
Here’s my code:
function matchURLs(text) {
const regex = /b(?:(?:https?://|www.)[a-zA-Z0-9.-]+.[a-zA-Z]{2,}(?:/S*)?|(?!.*@)[a-zA-Z0-9-]+.[a-zA-Z]{2,}(?:/S*)?)b/g;
const matches = text.match(regex);
if (matches?.length > 0) {
matches.forEach(match => {
if (!match.startsWith('http')) {
text = text.replace(match, `https://${match}`);
}
});
}
return text;
}
matchURLS(text)
These are the strings I’m passing to the function to match:
links like "google.com" are working
links "http://google.com" are working
links "https://google.com" are working
links "www.google.com" are working
links "http://www.google.com" are working
links "https://www.google.com" are working
email "[email protected]" are working
[email protected]
customer/[email protected]
[email protected]
this.is.a.very.long.email.address@subdomain.of.a.really.long.domain.name.com
And the output is this:
[
"google.com",
"http://google.com",
"https://google.com",
"www.google.com",
"http://www.google.com",
"https://www.google.com",
"google.com",
"exa4mple.com",
"exa5mple.com",
"mail.server",
"exa7mple.com",
"subdomain.of",
"a.really",
"long.domain",
"name.com"
]
Can someone help please to improve this regex so that it only matches the urls? So the first 6 only, and must not match url in email addresses, neither email addresses.
I’ve written a small application using HTML, JavaScript, and Node.js that allows saving strings to a database and a file on a server. However, the file upload is accompanied by an unwanted page reload. Can you please help me?
Here’s my repository :https://github.com/krommmm/unwantedReloadPage.git
I’m expecting the page to no reload on post fetch
I am using ‘expo-av’ in a bare react-native project to record audio. It is working fine on Android and 50% of the time on IOS.
The other 50% of the time it give the error.
prepare encountered an error: Error Domain=NSOSStatus error-Domain Code=561017449″Session Activation Failed”
I have searched long and hard so far my theory is that when some App or Service is using audio related API in the device it throws this error, but to handle this or check if the service is available or not there is not API provided by the “expo-av” library.
Can anyone give me useful insights or solutions to what is happening.
here is the recording function I am using to start the recording.
const startRecording = async () => {
try {
// Request microphone permissions
if (permissionResponse.status !== 'granted') {
console.log('Requesting permission..');
await requestPermission();
}
// Prepare audio recording options
await Audio.setAudioModeAsync({
allowsRecordingIOS: true,
playsInSilentModeIOS: true,
interruptionModeIOS: InterruptionModeIOS.DoNotMix,
interruptionModeAndroid: InterruptionModeAndroid.DoNotMix,
playsInSilentModeIOS: true,
staysActiveInBackground: true,
});
// Start recording
const {recording} = await Audio.Recording.createAsync(
Audio.RecordingOptionsPresets.HIGH_QUALITY,
);
setRecording(recording);
setIsRecording(true);
setIsPaused(false);
console.log('Recording started');
} catch (err) {
Alert.alert('Failed to start Recording: ' + err?.message);
console.error('Failed to start recording', err);
}
};

I did try another command npx tailwindcss-cli@latest init -p and created tailwind.config.js folder.
But I do want to know why the npx tailwind init: not working.
Tried ChatGPT and possible solution that I could get my hand on still the problem persists.

Following the documentation on Proxies on MDN, under the example bellow, there is this disclaimer:
If you use Reflect methods within a proxy trap, and the Reflect method
call gets intercepted by the trap again, there may be infinite
recursion.
The Proxy in the example is using Reflect in a Proxy trap, and, it works as expected, it causes no recursion.
So, in what case would the reflect call get "intercepted" and cause an infinite loop ? What should be avoided ?
const target = {
message1: "hello",
message2: "everyone",
};
const proxy3 = new Proxy(target, {
get(target, prop, receiver) {
if (prop === "message2") {
return "world";
}
return Reflect.get(...arguments);
},
});
console.log(target.message1)
console.log(target.message2)I have created a Here Map and have placed markers based on Data I have extracted using an api. I now would like to add a panel with selectable options to provide filtering options based on my data. I’m pretty new at this so would appreciate any assistance.
I have searched online but cannot find any examples relating to HERE maps, nor have I found any help in their documentation.

I’m working on a React application that receives a DOCX file as a base64 string from the backend. When I open this file in Google Docs, it displays edit suggestions/track changes clearly (as shown in the attached image). However, when I attempt to render the same DOCX using libraries like react-doc-viewer, the edit suggestions are not visible.
What I’ve Tried:
Converted base64 to downloadable DOCX file
Used multiple React libraries for DOCX rendering
Verified the issue is specifically with rendering track changes
Specific Requirements:
Render DOCX file with full track changes/edit suggestions in React UI
Preserve the formatting and edit history shown in Google Docs
Questions:
Which React library can render DOCX track changes?
Are there any JavaScript/web techniques to parse and display edit suggestions from DOCX files?
Additional Context:
Backend provides DOCX as base64 string
Goal is to display edits inline, similar to Google Docs view

I’m trying to set up jasmine-browser-runner for a TypeScript project.
My jasmine-config.mjs looks like this:
export default {
srcDir: 'src',
srcFiles: [],
specDir: 'src',
specFiles: [ './**/*Spec.ts' ],
helpers: ['jasmine-ts-node-register.js'],
enableTopLevelAwait: false,
env: {
stopSpecOnExpectationFailure: false,
stopOnSpecFailure: false,
random: true,
},
listenAddress: 'localhost',
hostname: 'localhost',
browser: { name: 'chrome' },
};
The helper jasmine-ts-node-register.js looks like this:
require('ts-node').register();
It is supposed to register ts-node, but it does not work, because require cannot be used in a browser. Running the tests with
npx jasmine-browser-runner runSpecs --config=./jasmine-config.mjs
fails with the error “No specs found”. But this is misleading, as specs are indeed found (I verified this by debugging jasmine-browser-runner), but none of them are actually called, because the helper above is called first, which aborts the tests. I changed a line in my local copy of jasmine-browser-runner that prevents Chrome from closing, and it reveals that, as expected, the require statement fails.
So, how can I set this up so that it actually works?
I could probably compile TypeScript files before calling jasmine-browser-runner, but I was hoping that I could set it up like to “watch” my files, which helps a lot when writing tests. Can I combine jasmine-browser-runner with webpack?
