first question here.

Does anyone know how to extend the response in Opine (Deno framework) so that I can create custom responses?

For example I would like to create:

res.success(message)

So that I don’t need to set HTTP codes every time like this:

res.setStatus(200).json({data: "success" });

I tried extending the response like it’s done here:
https://deno.land/x/[email protected]/test/units/app.response.test.ts

But when I use it in a controller I get:

Property ‘shout’ does not exist on type
‘OpineResponse’.deno-ts(2339)

Thank you.

I would be greatful if you could help me merging an action of use: and a function of on:click in one button in Sveltekit:

  <button
   class="notitle export"
   use:sth={exportBtnTrain}
   on:click={shareData('data', commentsArea.$value.value, screenshotImg)}
   >export data</button>

I’ve given the relative of the images on my personal portfolio website. but the images failed to load. The console shows the 404 error. In my local machine, the code and the path worked correctly but online the images not loading correctly.Nabeel Ahmed here is the link to my website.

I am new to chrome extensions, and I trying to figure out a solution for creating an extension that converts a website to a PDF. I am aware of the libraries for doing that, but in chrome extensions, it doesn’t work. So how can I do that? I also thought of creating a new webpage that interacts with the extension, so that I can handle importing libraries as content-scripts do not support importing modules. So actually I think that the way is to create another webpage, but how can I do that with extensions, and how does the communication work between webpages and extensions.
Best Regards,

Hello i have a trouble with my code.

I have HTML with JS:

$(document).ready(function () {
 
      // allowed maximum input fields
      var max_input = 5;
 
      // initialize the counter for textbox
      var x = 1;
 
      // handle click event on Add More button
      $('.add-btn').click(function (e) {
        e.preventDefault();
        if (x < max_input) { // validate the condition
          x++; // increment the counter
          $('.wrapper').append(`
            <div class="input-box">
              <input type="text" name="input_name[]"/>
              <input type="text" name="input_price[]">

I am currently fiddling with some exercise code, from what i seen in https://reactnavigation.org/docs/params/
You should be able to pass more than 1 params with route
But i can’t seem to do that .
I only manage to send 1 of the two params that i wanted to pass from Topping.js to Rasa.js
What am i possibly doing wrong ?
Any help is appreciated

Topping.js

export default function HalTopping({route,navigation}){ 
    const { JenisMie } = route.params;
    const TipeMie = JenisMie;

        return(

                <Text>itemId: {JSON.stringify(JenisMie)}</Text>
                <View style={styles.container}>

I am following this tutorial : https://www.codewall.co.uk/how-to-build-a-twitter-hashtag-viewing-tool-tutorial/
When i get to step Adjusting the index file to print hashtag variable passed in from the post handler i get a reference error.
I cannot see where is the problem as I am doing it step by step and the code is identical to the one provided in the tutorial.

Here is my server.js code :

const express = require('express')
const app = express()
const twit = require("twit")
app.set('view engine', 'ejs')
const bodyParser = require('body-parser')
app.use(bodyParser.urlencoded({ extended: true }));

// Start serv & listen on port 3000.
app.listen(3000, function () {
    console.log('Node listening on port 3000')
})

//Listen for get request on root url. eg. http://localhost:3000
//Listen for get request on root url. eg. http://localhost:3000
app.get('/', function (req, res) {
    res.render('index', { welcomeMessage: "Welcome to my app." })
})


let Twitter = new twit({
    consumer_key: '',
    consumer_secret: '',
    access_token: '',
    access_token_secret: '',
    timeout_ms: 60 * 1000, // optional HTTP request timeout to apply to all requests.
    strictSSL: true, // optional - requires SSL certificates to be valid.
});


Twitter.get('search/tweets', {
    q: '#100DaysOfCode',
    count: 100,
    result_type: "mixed"
}).catch(function (err) {
    console.log('caught error', err.stack)
}).then(function (result) {
    console.log('data', result.data);
});
app.post('/', function (req, res) {
    console.log(req.body.hashtag);
    if (req.body.hashtag !== undefined) {
      res.render('index',  {hashtag: req.body.hashtag})
    }
    res.render('index',  {hashtag: null})
    
  });

Here is my index.ejs code :

I’ve been trying to automate sending messages when some of my reports are uploaded through a checkbox trigger on Gscript. (Idea being report is updated-> User check the checkbox -> message is sent to slack)

So far, I’ve been able to create the script to send the message to slack, and even reset my checkboxes at night. The only issue I have is with the trigger.

I’ve used onEdit as a trigger, on my three checkboxes (A1,B1,C1):

function onEdit(e) {
  const as = e.source.getActiveSheet();
  const cell = e.range.getA1Notation();

  if(as.getName() == 'Sheet1' && cell.getRange('A1').ischecked() === true) {
    SendSlackMessage1();
  }
  else if (as.getName() == 'Sheet1' && cell.getRange('B1').ischecked() === true) {
    SendSlackMessage2();
  }
  else if (as.getName() == 'Sheet1' && cell.getRange('C1').ischecked() === true) {
    SendSlackMessage3();
  }}

As a reference here’s the function to send messages :

function SendSlackMessage1() {
  const url = "https://hooks.slack.com/services/XXXXXXXXXXXXX";
  const params = {
    method: "post",
    contentType: "application/json",
    payload: JSON.stringify({
      "text":"Report A has been uploaded"
    })
  }

  const sendMsg = UrlFetchApp.fetch(url, params)
  var respCode = sendMsg.getResponseCode()
  Logger.log(sendMsg)
  Logger.log(respCode)
}

(All of SendSlackmessages function are the same except for text (Report A/B/C), and I’ve already authorized the functions to run on google.

So obviously, I’m doing something wrong, but what ? my first guess would be that I’m not properly defining the e range, but I don’t know what to do next.

I’d be grateful if someone can give me a headstart or pointing me at where to look.
Thanks ! 😀

There is something I don’t understand with useState. This is my code :

const Home = () => {
    const [randomCharacters, setRandomCharacters] = useState([]);
    const [totalCharacters, setTotalCharacters] = useState('');


    useEffect(() => {
        axios.get('https://rickandmortyapi.com/api/character')
            .then((response) => {
                setTotalCharacters(response.data.info.count)
            })
    }, [])

    useEffect(() =>{
        axios.get('https://rickandmortyapi.com/api/character/1,23,'+ randomNumber(0, totalCharacters,4))
            .then((response) => {
                response.data.map(() => (
                    setRandomCharacters(response.data)
                ))
            })
    }, [])

    return (
        <div>
            <Navigation/>
            {randomCharacters.map( (character) => (
                <Card key={character.id} character={character}/>
            ))}
        </div>
    );
};

When I console.log totalCharactersjust after having set, I get ‘826’ and my cards are displayed but when I refresh the page or if I navigate to an other page and go back, totalCharacters equal to nothing. I guess it’s because by default useState = ” but why did it work the first time ? and How can I set the dynamic value

I’m using contextmenu event to capture right clicks. On touch devices that event fired via “long press”.

The problem I’m experiencing is that the contextmenu event doesn’t fire on touch devices until touch is released. I could listen for touchstart/mousedown events and set timeout, but it won’t be accurate since each device might have its own delay for long press activation.

So, is there a way accurately detect when long press is activated on touch screen devices? (On some devices there is haptic feedback when long press was activated)
