Hi @austere nymph. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

The code you provided seems to be written in plain JavaScript and directly manipulates the DOM, which is not the recommended way to handle things in a React or Next.js application. In Next.js, you should use React components and their lifecycle methods or hooks for such operations.
However, based on the information provided in the extracts, I can guide you on how to use scripts in Next.js. You can use the next/script component to include third-party scripts in your Next.js application. Here's an example of how to use it:
import Script from 'next/script'
export default function Home() {
return (
<div className="container">
<Script id="google-analytics">
{`
// Your script here
`}
</Script>
</div>
)
}
You can also use event handlers like onLoad, onReady, and onError with the Script component to execute additional code after a certain event occurs. However, these handlers will only work when next/script is imported and used inside of a Client Component where "use client" is defined as the first line of code. Here's an example:
'use client'
import Script from 'next/script'
export default function Page() {
return (
<>
<Script
src="<https://example.com/script.js">
onLoad={() => {
console.log('Script has loaded')
}}
/>
</>
)
}
Please note that onLoad and onReady do not yet work with Server Components and can only be used in Client Components. If you are loading a script with either afterInteractive or lazyOnload as a loading strategy, you can execute code after it has loaded using the onLoad property.
For more details, you can refer to the Next.js documentation on the Script component (https://nextjs.org/docs/app/api-reference/components/script).
However, to fully convert your code to work with Next.js, you might need to refactor it to use React's way of handling events and state. If you need help with that, I would recommend looking into React's documentation on hooks (https://reactjs.org/docs/hooks-intro.html) and events (https://reactjs.org/docs/handling-events.html).

Let me check the knowledge base for you. One moment! :books:
The issue with your code is that you're trying to directly manipulate the DOM using JavaScript inside a React component. This is not the recommended way to handle things in a React or Next.js application.
In Next.js, you should use React components and their lifecycle methods or hooks for such operations. The window.onload and window.onresize events should be handled using the useEffect hook in React.
Also, the document.getElementById method is not recommended in React. Instead, you should use the useRef hook to get a reference to the DOM element.
Here's how you can refactor your code to work with Next.js:
import React, { useEffect, useRef } from "react";
function MatrixPage() {
const canvasRef = useRef(null);
useEffect(() => {
const canvasTag = canvasRef.current;
// rest of your code here
}, []);
useEffect(() => {
function handleResize() {
const canvasTag = canvasRef.current;
// your resize code here
}
window.addEventListener('resize', handleResize);
return () => {
window.removeEventListener('resize', handleResize);
};
}, []);
return (
<canvas ref={canvasRef} id="matrix_" />
);
}
export default MatrixPage;
In this code, I've used the useRef hook to get a reference to the canvas element. Then, I've used the useEffect hook to run your code once the component has mounted. I've also added another useEffect hook to handle the resize event.
Please note that you might need to adjust this code to fit your needs, as I've omitted the details of your code for brevity. For more information on how to use hooks in React, you can refer to the React documentation (https://reactjs.org/docs/hooks-intro.html).

Sure, here's how you can refactor your code to use the useEffect hook:
import React, { useEffect, useRef } from "react";
function MatrixPage() {
const canvasRef = useRef(null);
useEffect(() => {
const canvasTag = canvasRef.current;
function getWindowSize() {
canvasTag.height = window.innerHeight;
canvasTag.width = window.innerWidth;
}
function Load() {
getWindowSize();
const letter_size = 16; //letters size
const columnsNumber = canvasTag.width / letter_size; //Get the number of columns
let letters = [];
for (let i = 0; i < columnsNumber; i++) {
letters[i] = 1;
}
let context = canvasTag.getContext('2d');//canvas
function canvasCreator() {
context.fillStyle = "rgba(0,0,0,0.08)";//canvas background
context.fillRect(0, 0, canvasTag.width, canvasTag.height);
context.fillStyle = "#0f0";//letters color
context.font = letter_size + "px arial";//letters font
let text;
let allText;
for (let i = 0; i < letters.length; i++) {
text = Create_Word();
allText = text.split("");
context.fillText(allText, i * letter_size, letters[i] * letter_size);
if (letters[i] * letter_size > canvasTag.height && Math.random() > 0.975) {
letters[i] = 0;
}
letters[i]++;
}
}
let numberText
function Create_Word() {
numberText = Math.floor((Math.random() * 94) + 33);//Create char from code
return String.fromCharCode(parseInt(numberText));//return char code
}
setInterval(canvasCreator, 80);//Timer
}
Load();
}, []);useEffect(() => {
function handleResize() {
const canvasTag = canvasRef.current;
canvasTag.height = window.innerHeight;
canvasTag.width = window.innerWidth;
}
window.addEventListener('resize', handleResize);
return () => {
window.removeEventListener('resize', handleResize);
};
}, []);
return (
<canvas ref={canvasRef} id="matrix_" />
);
}
export default MatrixPage;
In this code, I've moved your `Load` function and the `getWindowSize` function inside the `useEffect` hook. The `Load` function is then called immediately after being defined. This will ensure that your code runs once the component has mounted.
The `handleResize` function is defined in another `useEffect` hook to handle the `resize` event. This function is added as an event listener to the `window` object, and it's removed when the component unmounts.
Please note that you might need to adjust this code to fit your needs. For more information on how to use hooks in React, you can refer to the **React documentation** (<https://reactjs.org/docs/hooks-intro.html>).

I apologize for the confusion. Here's the TypeScript version of the code:
import React, { useEffect, useRef } from "react";
const MatrixPage: React.FC = () => {
const canvasRef = useRef<HTMLCanvasElement | null>(null);
useEffect(() => {
const canvasTag = canvasRef.current;
if (!canvasTag) return;
function getWindowSize() {
canvasTag.height = window.innerHeight;
canvasTag.width = window.innerWidth;
}
function Load() {
getWindowSize();
const letter_size = 16; //letters size
const columnsNumber = canvasTag.width / letter_size; //Get the number of columns
let letters = Array(columnsNumber).fill(1);
let context = canvasTag.getContext('2d');//canvas
function canvasCreator() {
if (!context) return;
context.fillStyle = "rgba(0,0,0,0.08)";//canvas background
context.fillRect(0, 0, canvasTag.width, canvasTag.height);
context.fillStyle = "#0f0";//letters color
context.font = `${letter_size}px arial`;//letters font
let text;
let allText;
for (let i = 0; i < letters.length; i++) {
text = Create_Word();
allText = text.split("");
context.fillText(allText.join(''), i * letter_size, letters[i] * letter_size);
if (letters[i] * letter_size > canvasTag.height && Math.random() > 0.975) {
letters[i] = 0;
}
letters[i]++;
}
}
function Create_Word() {
const numberText = Math.floor((Math.random() * 94) + 33);//Create char from code
return String.fromCharCode(parseInt(numberText.toString()));//return char code
}
setInterval(canvasCreator, 80);//Timer
}
Load();
}, []);
useEffect(() => {
function handleResize() {
const canvasTag = canvasRef.current;
if (!canvasTag) return;canvasTag.height = window.innerHeight;
canvasTag.width = window.innerWidth;
}
window.addEventListener('resize', handleResize);
return () => {
window.removeEventListener('resize', handleResize);
};
}, []);
return (
<canvas ref={canvasRef} id="matrix_" />
);
}
export default MatrixPage;
In this TypeScript version, I've added type annotations to your code. The `canvasRef` is now a `React.RefObject` that can hold either a `HTMLCanvasElement` or `null`. I've also added null checks to make sure that `canvasTag` and `context` are not `null` before using them. This is necessary because in TypeScript, values can be `null` or `undefined`, and trying to access properties or methods on `null` or `undefined` values will cause a type error.
