If it were you which are you choosing and why:
1- C# + SQL-SERVER+ .NET .
2- JavaScript + MongoDb + Node.js .
3- Php + MySql + Laravel .
I am new and i want some advice and help to know facts about this field to know what to choose
I am setting up environment variabes for the keys needed for sending an email through emailjs. I have tried putting the values in directly to make sure it works, and it works fine, but when I store the values in environment variables, for some reason I am getting undefined values. I have done this before this exact same way so I am not sure whats going on.
here are the environment variables:
REACT_APP_EMAIL_SERVICE_ID=myServiceId
REACT_APP_EMAIL_PUBLIC_KEY=myPublicKey
REACT_APP_EMAIL_TEMPLATE_ID=myTemplateId
and here is where I use it in my send email function:
import emailjs from "@emailjs/browser"
export default async function sendEmail(formData){
const serviceId = process.env.REACT_APP_EMAIL_SERVICE_ID
const templateId = process.env.REACT_APP_EMAIL_TEMPLATE_ID
const publicKey = process.env.REACT_APP_EMAIL_PUBLIC_KEY
const templateparams = {
from_name: formData.firstname + " " + formData.lastname,
email: formData.email,
to_name: "my name",
message: formData.message
}
console.log(publicKey)
emailjs.send(serviceId, templateId, templateparams, publicKey)
.then(res =>{
console.log('Email sent successfully')
alert('Email sent successfully')
formData.firstname = ''
formData.lastname = ''
formData.email = ''
formData.message = ''
})
.catch(err =>{
console.log('Error sending email', err)
alert('Error sending email')
formData.firstname = ''
formData.lastname = ''
formData.email = ''
formData.message = ''
})
return formData
}
First time deploying on Heroku and I’ve come across this hurdle that won’t let me successfully deploy my discord bot. I’ve been following a tutorial and the creator seemed to deploy his project on the platform no problem, however as with most things, it hasn’t been as straightforward the past hour.
The jist being the Error: cannot find module './discord.js'
I tried the solution from this answer, but no luck.
Here is my package.json:
"name": "booster-bot",
"version": "1.0.0",
"main": "index.js",
"engines": {
"node": "12.14.1",
"npm": "6.13.4"
},
"repository": {
"type": "git",
"url": "git+link"
},
"scripts": {
"test": "echo "Error: no test specified" && exit 1",
"start": "node bot.js",
"devStart": "nodemon bot.js"
},
"keywords": [],
"author": "",
"license": "ISC",
"description": "",
"dependencies": {
"dotenv": "^16.4.5",
"requirements-txt": "^0.0.5"
},
"devDependencies": {
"nodemon": "^3.1.4"
}
}
As well as the block of code it points back to:
const {
Client,
Events,
GatewayIntentBits,
EmbedBuilder,
} = require("./discord.js");
const client = new Client({
partials: ["GUILD_MEMBER"],
intents: [
GatewayIntentBits.Guilds,
GatewayIntentBits.GuildMessages,
GatewayIntentBits.MessageContent,
GatewayIntentBits.GuildMembers,
GatewayIntentBits.GuildPresences,
],
});
To note is that I initially did not have the ./ in the ./discord.js, but as per this other answer and my desperation, I thought I’d try it (didn’t work). I also have the Procfile turned on and the requirements.txt installed, showing in this snippet on my package.json file:
"name": "booster-bot",
"version": "1.0.0",
"lockfileVersion": 3,
"requires": true,
"packages": {
"": {
"name": "booster-bot",
"version": "1.0.0",
"license": "ISC",
"dependencies": {
"dotenv": "^16.4.5",
"requirements-txt": "^0.0.5"
},
"devDependencies": {
"nodemon": "^3.1.4"
},
"engines": {
"node": "12.14.1",
"npm": "6.13.4"
}
},
Thank you for any input / help!
I am using https://github.com/IndieKKY/bilibili-subtitle on Bilibili and at first I can clearly see the content in the extension after it loads. However, when I use the javascript code to get the content, it says undefined until I explicitly inspect a text inside the extension and rerun the code. I am running on Brave Browser and Chrome.
The code is:
var spans = document.querySelectorAll('span[style="display: inline;"]');
var concatenatedText = Array.from(spans).map(function(span) {
var textElement = span.querySelector('text.font-medium');
return textElement ? textElement.textContent : null;
}).filter(Boolean).join(', ');
console.log(concatenatedText);
And the video is:
https://drive.google.com/file/d/1TT6IvVopNOyWGBibNGyGF-o0oEFbTl4l/view?usp=sharing
Any idea what is going on?
I am planning to visit consecutive urls in the playlist in a loop and run this code but since the extension code never gets recognized properly on the first try its not going to work out.
Any help would be appreciated! Perhaps it has to do with some dynamically added content? I’ve looked for similar topics as well like this: Dynamically added HTML not being recognized by jQuery
but my attempts to modify the code have not worked so far?
I would like to SSR the homepage from a node express server to a react nextJS client without using dangerouslySetInnerHTML.
The server and client are in separate directories.
I have verified the server successfully serves this JSX to the browser b/c I can go to localhost:5000 where the server is running and see the rendered HTML.
// server.js file in node express repo
// Serve SSR React component
app.get("/", (req, res) => {
const appHtml = ReactDOMServer.renderToString(<SSRApp />);
res.send(`
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>SSR App</title>
</head>
<body>
<div id="root">${appHtml}</div>
</body>
</html>
`);
});
const PORT = process.env.PORT || 5000;
app.listen(PORT, () => {
console.log(`Server is running on http://localhost:${PORT}`);
});
However, when running the nextJS client on port 3000, I’m only able to render the JSX from the server if I use dangerouslySetInnerHTML:
// page.js file in next client repo
import React from "react";
export default async function HomePage() {
// Fetch the SSR HTML from your Express server
const res = await fetch("http://localhost:5000", {
cache: "no-store",
});
const ssrHtml = await res.text();
return (
<div>
<div dangerouslySetInnerHTML={{ __html: ssrHtml }} />
</div>
);
}
I’m aware you can sanitize the input to reduce risk of XSS attacks but I’d prefer to avoid dangerouselySetInnerHTML all together.
How can I SSR from a node express server to a nextJS react client and allow the client to hydrate the JSX from the server in a nextJS app without using dangerouslySetInnerHTML?
I’m trying to build my current project it in a way so my friends can create servers on one network so we can connect to each other (LAN communication, pretty much). The only problem is when I run my program in two terminal windows, my second run fails and throws errors at me because ports are already taken, which is logical.
I am working with Vite, express, and ws. This is one of my server’s code.
const { WebSocketServer } = require('ws')
const sockserver1 = new WebSocketServer({ port: 311 })
sockserver1.on('connection', ws => {
sockserver1.clients.forEach(client => {
client.send(`A new player connection has been established`);
})
ws.on('message', data => {
sockserver1.clients.forEach(client => {
client.send(`${data}`)
})
})
ws.on('close', () => {
sockserver1.clients.forEach(client => {
client.send(`A player has disconnected`)
})
})
ws.onerror = function () {
console.log('websocket error')
}
});
When I run this the second time, it will fail and say that port ::311 is taken. How can I add 1 to the port number till I find one that isn’t taken? I have notice Vite does this.
I want to test the following Svelte component with Vitest:
<script context="module">
import {push} from 'svelte-spa-router'
import {onDestroy} from 'svelte'
let time = 1000*120;
let interval = 1000;
let running = true;
export const twoDigits = (number) => {
return number.toLocaleString('en-US', {
minimumIntegerDigits: 2,
useGrouping: false
})
}
export const timeString = (ms) => {
let seconds = ms / 1000;
const minutes = Math.floor(seconds / 60);
seconds = seconds % 60;
const timeString = twoDigits(minutes) + ":" + twoDigits(seconds);
return timeString
}
let timeShown = timeString(time)
export const startCountdown = () => {
setTimeout(()=>{
time -= interval;
timeShown = timeString(time);
if (time > 0 && running) {
startCountdown();
} else if (time > 0 && !running) {
console.log("Countdown stopped")
} else {
console.log("Done!")
setTimeout( () => {
push('/gameover')
},1000)
}
}, interval)
}
startCountdown()
onDestroy(()=>{
running = false;
})
</script>
<div id="countdown">
{timeShown}
</div>
Unfortunately, I get an error saying Function called outside component initialization as soon as I try to import the component in my test file with import Countdown from "../lib/Countdown.svelte".
The problem could have something to do with the onDestroy function but I don’t know, how to fix this.
After using the fetch request to get data, I assigned some values of the data to other variables. However, when I call these variables in subsequent code, they show undefined, while inside the fetch request body these variables have values. What could be the reason for this, and how can I resolve this issue?
Here is the specific code:
let machineTypeArr, machineModelArr, machineBrandArr, machineSupplierArr, machineArr;
function getMachineInfo() {
fetch('/machineInfoConfig?handlerType=getMachineInfo')
.then(response => response.json())
.then(data => {
// console.log(data);
// console.log(data.machineType);
// console.log(data.machineModel);
// console.log(data.machineBrand);
// console.log(data.machineSupplier);
// console.log(data.machine);
// machineTypeArr = JSON.parse(JSON.stringify(data.machineType));
// machineModelArr = JSON.parse(JSON.stringify(data.machineModel));
// machineBrandArr = JSON.parse(JSON.stringify(data.machineBrand));
// machineSupplierArr = JSON.parse(JSON.stringify(data.machineSupplier));
// machineArr = JSON.parse(JSON.stringify(data.machine));
machineTypeArr = data.machineType;
machineModelArr = data.machineModel;
machineBrandArr = data.machineBrand;
machineSupplierArr = data.machineSupplier;
machineArr = data.machine;
typeLen = machineTypeArr.length;
brandLen = machineBrandArr.length;
modelLen = machineModelArr.length;
supplierLen = machineSupplierArr.length;
machineLen = machineArr.length;
// console.log(typeLen, modelLen, brandLen, supplierLen, machineLen);
// console.log(machineArr);
// console.log(machineTypeArr);
// console.log(machineModelArr);
// console.log(machineBrandArr);
// console.log(machineSupplierArr);
// loadTableInfo();
})
}
window.onload = function() {
getMachineInfo();
console.log(typeLen, modelLen, brandLen, supplierLen, machineLen);
console.log(machineArr);
console.log(machineTypeArr);
console.log(machineModelArr);
console.log(machineBrandArr);
console.log(machineSupplierArr);
}
I already checked with the search engine and gpt.
I don’t know what the exact problem is.
I want to know why this situation will happen.
I’m new on React Native world, and I’m trying to store data on SQL Lite.
I have an expo React Native project, with SQL Lite and TypeORM configured (I followed the documentation).
The problem is that TypeORM is never saving data on the database.
Here is the entity that I’m trying to save:
import {
Entity,
Column,
PrimaryColumn,
} from 'typeorm/browser';
import { User } from '../user/User';
@Entity('wallet')
export class Wallet {
@PrimaryColumn()
id: string;
@Column()
name: string;
@Column()
accountId: string;
@Column()
amount: number;
}
ID is generated by my backend service, so this is why is not a @PrimaryGeneratedColumn.
Here is the piece of code that I’m trying to use to save the data:
... some imports ....
import * as SQLite from 'expo-sqlite/legacy';
import { DataSource, Repository } from 'typeorm/browser';
import { Wallet } from '@/data/wallet/Wallet';
....
export default function HomeScreen()
const network = useNetwork();
const dataSource = new DataSource({
database: "test_db_local",
driver: SQLite,
entities: [
Wallet,
User,
Financial
],
synchronize: true,
type: "expo",
})
let walletRepo: Repository<Wallet> = null;
const call = useCallback(async () => {
let wallet = new Wallet();
wallet.accountId = "b8d89f94-516a-4ff0-9dac-257f25587b81";
wallet.name = 'Default'
let result: Response = await network.doPost("wallets", JSON.stringify(wallet));
if (result.status !== 201) {
throw new Error();
}
let body = await result.json();
wallet.id = body.id;
if (!dataSource.isInitialized) {
var source = await dataSource.initialize();
walletRepo = await source.getRepository(Wallet);
}
let all = await walletRepo.createQueryBuilder("wallet").getMany();
console.log(all)
console.log("SAVING")
walletRepo.save(wallet).then(res => console.log(res)).catch(err => console.log(err));
}, [])
useEffect(() => {
call().catch(err => console.log(err));
}, [])
.... THE REST OF MY CODE ....
So, as you can see, I’m running a query to findAll before to see if there’s something on the DB.This query is executed and return an empty array.
Then I run the insert method. The problem is here. It never works. It get stuck on saving and never run the “then” or the “catch”.
I’ve tried changing it to “.insert” but there’s no difference.
The data is not being saved on the local SQL Lite.
About my environment: I’m executing the App in An Android Phone (Samsung S21) through Expo App.
Do you guys have any idea of what is going on?

I was working on a project to build a simple UI of chessboard using react for practice. I have encountered a problem where I am unable to render a given piece on a specific tile. Can anyone help me on where the potential issue may lie? I have made sure the image path is correct. It is located in the images folder inside the public folder.
PS: I am a beginner, I don’t know much.
//Typescript for react component
import './chessboard.css';
import Tile from "../Tiles/tile";
interface piece {
image?: string;
x: number;
y: number;
}
const pieces: piece[] = [];
const horizontalAxis = ["a", "b", "c", "d", "e", "f", "g", "h"];
const verticalAxis = [1, 2, 3, 4, 5, 6, 7, 8];
pieces.push({ image: "/images/black_pawn.png", x: 0, y: 1 });
export default function Chessboard() {
let board = [];
for (let j = verticalAxis.length - 1; j >= 0; j--) {
for (let i = 0; i < horizontalAxis.length; i++) {
const number = i + j + 2;
let image = undefined;
pieces.forEach(p => {
if (p.x === i && p.y === j) {
image = p.image;
}
});
board.push(<Tile image={image} number={number} />);
}
}
return <div id="chessboard">{board}</div>;
}
//TypeScript for tile component
import './tile.css';
interface props{
image?: string;
number: number;
}
export default function Tile({image, number}: props){
if(number%2===0){
return (<div className="tile black-tile"></div>)
}else{
return (<div className="tile white-tile"></div>)
}

JavaScript =”javascript:void(window.open(‘https://p21.castertech.com/Prophet21/index.html#/window/m_customermasterinquiry?customer_id=” & parameters!CustID.value & “‘,’_blank’))”
When I go the command line of the Brower and fill in custid with a value such as =javascript:void(window.open(‘https://p21.castertech.com/Prophet21/index.html#/window/m_customermasterinquiry?customer_id=50′,’_blank’))” for testing it works.
When I click on the image on the Report with the same date nothing happens. Not sure what I am doing wrong. Brower is chrome, Java is on, SSRS Current Version 15
One other note I have scripts on textbox properties again go to statements
=”javascript:void(window.open(‘https://p21.castertech.com/Prophet21/index.html#/window/m_orderentry?order_no=” & Fields!order_number.Value & “‘,’_blank’))”
that are not working also.
Any help would be very much appreciated
