react-ace
Advanced tools
The react-ace package is a React component for the Ace editor, which is a powerful code editor written in JavaScript. It allows you to embed the Ace editor into your React applications, providing a rich set of features for code editing, syntax highlighting, and more.
Basic Usage
This code demonstrates the basic usage of the react-ace package. It imports the necessary modules and sets up an Ace editor with JavaScript mode and the GitHub theme.
import React from 'react';
import AceEditor from 'react-ace';
import 'ace-builds/src-noconflict/mode-javascript';
import 'ace-builds/src-noconflict/theme-github';
function MyEditor() {
return (
<AceEditor
mode="javascript"
theme="github"
name="editor"
editorProps={{ $blockScrolling: true }}
/>
);
}
export default MyEditor;
Customizing Editor Options
This code sample shows how to customize various options of the Ace editor, such as font size, print margin, gutter, active line highlighting, and enabling autocompletion and snippets.
import React from 'react';
import AceEditor from 'react-ace';
import 'ace-builds/src-noconflict/mode-javascript';
import 'ace-builds/src-noconflict/theme-github';
function MyEditor() {
return (
<AceEditor
mode="javascript"
theme="github"
name="editor"
fontSize={14}
showPrintMargin={true}
showGutter={true}
highlightActiveLine={true}
setOptions={{
enableBasicAutocompletion: true,
enableLiveAutocompletion: true,
enableSnippets: true,
showLineNumbers: true,
tabSize: 2,
}}
/>
);
}
export default MyEditor;
Handling Editor Events
This example demonstrates how to handle events in the Ace editor. The onChange event is used to log the new value of the editor whenever it changes.
import React from 'react';
import AceEditor from 'react-ace';
import 'ace-builds/src-noconflict/mode-javascript';
import 'ace-builds/src-noconflict/theme-github';
function MyEditor() {
const onChange = (newValue) => {
console.log('change', newValue);
};
return (
<AceEditor
mode="javascript"
theme="github"
name="editor"
onChange={onChange}
/>
);
}
export default MyEditor;
The react-codemirror2 package is a React component for the CodeMirror editor. It provides similar functionalities to react-ace, such as syntax highlighting, code folding, and customizable themes. However, CodeMirror is known for its flexibility and extensive list of supported languages and modes.
The react-monaco-editor package is a React component for the Monaco editor, which is the code editor that powers Visual Studio Code. It offers advanced features like IntelliSense, parameter hints, and a rich API for extensions. Compared to react-ace, react-monaco-editor provides a more feature-rich and modern editing experience.
The react-simple-code-editor package is a lightweight code editor component for React. It is built on top of the Prism syntax highlighter and is designed to be simple and easy to use. While it lacks some of the advanced features of react-ace, it is a good choice for basic code editing needs.
