Prism.js – Simple Syntax Highlighter

Installation

bash npm install prismjs --save

Basic Usage

tsx // src/components/PrismHighlight.tsx

import Prism from 'prismjs';import 'prismjs/mes/prism-tomorrow.css';// choose your me

// Register languages you plan to highlight. import 'prismjs/components/prism-javascript';import 'prismjs/components/prism-typescript';import 'prismjs/components/prism-jsx';

export interface HighlightProps { 至于code，string;language: string;}

export const PrismHighlight = => { const highlighted = Prism.highlight( code。Prism.languages,language,);

return ( <> {/* eslint-disable-next-line react/no-danger /}

language-${language}}>
{/

@uiw/react-codemirror – Lightweight Interactive Editor

Installation

bash npm i @uiw/react-codemirror @codemirror/lang-javascript

Basic Usage

tsx // src/components/CmEditor.tsx

import * as React from 'react';import CodeMirror from '@uiw/react-codemirror';import { javascript } from '@codemirror/lang-javascript';

const CmEditor = => { const = React.useState( console.log;,)，老实说，

return ( <> {/* Height can be responsive or fixed /} {/ height=\"100%\" works inside flex containers /} / eslint-disable-next-line react/jsx-props-no-spreading */ );}，

export default CmEditor;

Multi‑Language Support Example

/* Add imports for or languages */ import { python } from '@codemirror/lang-python';import { html } from '@codemirror/lang-html';

export const MultiLangCm = => { const = React.useState;const extensions = lang === 'python' : lang === 'html' :;

return ( <> ... );}，

@monaco-editor/react – Full‑Featured VS Code Experience

Installation

bash npm i @monaco-editor/react --save-dev // dev dependency recommended for large bundle size.

Basic Usage With Lazy Load

tsx // src/App.tsx

/* Lazy load Monaco */ const MonacoEditor = React.lazy => import,);

function App { return (

export default App;

Custom Theme Example

tsx // src/ThemedMonaco.tsx

const CustomThemeMonaco = => { return ( /* Before mount you can register a custom me / / This will be applied when me prop equals custom-me / / Remember to import monaco types if using TypeScript / / eslint-disable-next-line react/jsx-filename-extension / / eslint-disable-next-line react/jsx-props-no-spreading */ Monocaditor({ height这方面。"90vh",defaultLanguage:"typescript",me:"custom-me",beforeMount:=>{ monaco.editor.defineTheme('custom-me',{ base这方面，'vs-dark',inherit:true,rules:,colors:{'editor.background':'#1E1E1E'},});} })

);}，

export default CustomThemeMonaco;

⚡ Performance Tweaks & Best Practices

1. Lazy Loading Heavy Editors – As shown above with React.lazy + Suspense.

   tsx jsx import { lazy,Suspense }from"react";const LazyMonaco = lazy=> import);

   function Demo{ return});}

2. Responsive Height – Avoid hard‑coded pixel heights unless necessary.

   tsx jsx /* For example inside a flex column */ export default =>( <> {/* Using % height within a parent that has defined height */} {/* This keeps layout fluid across breakpoints */} {...} );

3. *Selective Language Imports * – Import only cores you need to shrink bundle size.

   ts jsx // Instead of importing all languages:

   import PrismCore from "prismjs/components/prism-core";

   // Import specific tokens:

   import "prisma/js";// JS syntax only

4. Throttle Change Events – When listening to onChange,debounce updates if y trigger heavy side effects such as linting or server calls.

5. Use key Prop Carefully – Avoid remounting editors by keeping stable keys unless intentionally resetting state.

🎯 Summary Checklist

1️⃣ Prisma.js – Pure syntax highlighter ➜ If you only need static display.

2️⃣ @uiw/react-codemirror – Light yet functional ➜ If you want an interactive playground without huge bundles.

3️⃣ @monaco-editor/react – Full IDE capability ➜ If your project demands advanced refactoring tools。multi-file support,or VS Code feel.

Pick according to your priority on bundle size vs feature richness and adapt above snippets into your project’s architecture accordingly!
