Competitor Comparisons
Ace (Ajax.org Cloud9 Editor)
Pros of ace
- More comprehensive and feature-rich, offering a wider range of functionalities
- Directly customizable with extensive API and configuration options
- Larger community and more frequent updates
Cons of ace
- Steeper learning curve due to its complexity
- Heavier in size, which may impact load times and performance
- Not specifically designed for React, requiring additional setup for integration
Code Comparison
ace:
var editor = ace.edit("editor");
editor.setTheme("ace/theme/monokai");
editor.session.setMode("ace/mode/javascript");
react-ace:
import AceEditor from 'react-ace';
<AceEditor
mode="javascript"
theme="monokai"
onChange={onChange}
name="editor"
editorProps={{ $blockScrolling: true }}
/>
The ace library provides a more low-level API for creating and configuring the editor, while react-ace offers a React-specific component with props for easy integration. react-ace simplifies the process of using ace within React applications, but may limit some advanced customizations that are possible with the core ace library.
In-browser code editor (version 5, legacy)
Pros of CodeMirror 5
- More extensive language support and syntax highlighting options
- Highly customizable with a wide range of plugins and addons
- Better performance for large documents and complex editing operations
Cons of CodeMirror 5
- Steeper learning curve for integration and customization
- Larger bundle size, which may impact load times for web applications
- Less straightforward React integration compared to React-Ace
Code Comparison
React-Ace:
import AceEditor from 'react-ace';
<AceEditor
mode="javascript"
theme="monokai"
onChange={handleChange}
name="codeEditor"
editorProps={{ $blockScrolling: true }}
/>
CodeMirror 5:
import CodeMirror from 'codemirror';
import 'codemirror/mode/javascript/javascript';
useEffect(() => {
const editor = CodeMirror.fromTextArea(textareaRef.current, {
mode: 'javascript',
theme: 'monokai'
});
editor.on('change', handleChange);
}, []);
Both React-Ace and CodeMirror 5 are popular code editor libraries, but they cater to different use cases. React-Ace provides a more straightforward integration for React applications, while CodeMirror 5 offers greater flexibility and customization options. The choice between the two depends on the specific requirements of your project, such as the need for extensive language support, performance considerations, and the level of customization required.
A browser based code editor
Pros of monaco-editor
- More comprehensive feature set, including IntelliSense, code folding, and multi-language support
- Better performance for large files and complex syntax highlighting
- Extensive customization options and API for advanced use cases
Cons of monaco-editor
- Larger bundle size, which may impact load times for smaller projects
- Steeper learning curve due to its complexity and extensive API
- May be overkill for simple code editing tasks
Code Comparison
monaco-editor:
import * as monaco from 'monaco-editor';
const editor = monaco.editor.create(document.getElementById('container'), {
value: 'console.log("Hello, world!");',
language: 'javascript'
});
react-ace:
import AceEditor from 'react-ace';
<AceEditor
mode="javascript"
theme="github"
value="console.log('Hello, world!');"
onChange={handleChange}
/>
Summary
monaco-editor offers a more powerful and feature-rich editing experience, suitable for complex projects and IDEs. react-ace provides a simpler, lightweight solution for basic code editing in React applications. Choose based on your project's requirements and complexity.
A terminal for the web
Pros of xterm.js
- Full-featured terminal emulator with extensive compatibility
- Supports a wide range of terminal protocols and escape sequences
- Highly customizable with numerous add-ons and extensions
Cons of xterm.js
- Steeper learning curve for basic implementation
- Larger bundle size due to comprehensive feature set
- May require additional configuration for React integration
Code Comparison
xterm.js:
import { Terminal } from 'xterm';
import 'xterm/css/xterm.css';
const term = new Terminal();
term.open(document.getElementById('terminal'));
term.write('Hello from \x1B[1;3;31mxterm.js\x1B[0m $ ');
react-ace:
import AceEditor from 'react-ace';
import 'ace-builds/src-noconflict/mode-javascript';
import 'ace-builds/src-noconflict/theme-monokai';
<AceEditor
mode="javascript"
theme="monokai"
onChange={onChange}
name="UNIQUE_ID_OF_DIV"
editorProps={{ $blockScrolling: true }}
/>
Summary
xterm.js is a powerful terminal emulator with broad compatibility and customization options, while react-ace is a React-specific code editor component. xterm.js offers more terminal-like functionality but may require more setup, especially in React environments. react-ace provides a simpler integration for code editing in React applications but lacks the full terminal emulation capabilities of xterm.js.
CodeMirror 6 component for React. @codemirror https://uiwjs.github.io/react-codemirror/
Pros of react-codemirror
- More lightweight and faster performance
- Better TypeScript support and type definitions
- More frequent updates and active maintenance
Cons of react-codemirror
- Fewer language modes and themes available out-of-the-box
- Less extensive documentation compared to react-ace
- Smaller community and fewer third-party extensions
Code Comparison
react-codemirror:
import CodeMirror from '@uiw/react-codemirror';
import { javascript } from '@codemirror/lang-javascript';
<CodeMirror
value="console.log('hello world!');"
height="200px"
extensions={[javascript({ jsx: true })]}
onChange={(value, viewUpdate) => {
console.log('value:', value);
}}
/>
react-ace:
import AceEditor from "react-ace";
import "ace-builds/src-noconflict/mode-javascript";
import "ace-builds/src-noconflict/theme-github";
<AceEditor
mode="javascript"
theme="github"
onChange={(newValue) => console.log('value:', newValue)}
name="UNIQUE_ID_OF_DIV"
editorProps={{ $blockScrolling: true }}
/>
Both libraries provide React components for code editing, but react-codemirror offers a more modern and lightweight approach with better TypeScript support. react-ace, on the other hand, has a larger ecosystem and more extensive language and theme options available by default. The choice between the two depends on specific project requirements and preferences.
