Install

Not dependent on uiw.

npm install @uiw/react-codemirror --save

Usage

Open in CodeSandbox

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

function App() {
  const onChange = React.useCallback((value, viewUpdate) => {
    console.log('value:', value);
  }, []);
  return (
    <CodeMirror
      value="console.log('hello world!');"
      height="200px"
      extensions={[javascript({ jsx: true })]}
      onChange={onChange}
    />
  );
}
export default App;

Support Language

Open in CodeSandbox

import CodeMirror from '@uiw/react-codemirror';
import { StreamLanguage } from '@codemirror/language';
import { go } from '@codemirror/legacy-modes/mode/go';

const goLang = `package main
import "fmt"

func main() {
  fmt.Println("Hello, 世界")
}`;

export default function App() {
  return <CodeMirror value={goLang} height="200px" extensions={[StreamLanguage.define(go)]} />;
}

Markdown Example

Markdown language code is automatically highlighted.

Open in CodeSandbox

import CodeMirror from '@uiw/react-codemirror';
import { markdown, markdownLanguage } from '@codemirror/lang-markdown';
import { languages } from '@codemirror/language-data';

const code = `## Title

\`\`\`jsx
function Demo() {
  return <div>demo</div>
}
\`\`\`

\`\`\`bash
# Not dependent on uiw.
npm install @codemirror/lang-markdown --save
npm install @codemirror/language-data --save
\`\`\`

[weisit ulr](https://uiwjs.github.io/react-codemirror/)

\`\`\`go
package main
import "fmt"
func main() {
  fmt.Println("Hello, 世界")
}
\`\`\`
`;

export default function App() {
  return <CodeMirror value={code} extensions={[markdown({ base: markdownLanguage, codeLanguages: languages })]} />;
}

Support Hook

Open in CodeSandbox

import { useEffect, useMemo, useRef } from 'react';
import { useCodeMirror } from '@uiw/react-codemirror';
import { javascript } from '@codemirror/lang-javascript';

const code = "console.log('hello world!');\n\n\n";
// Define the extensions outside the component for the best performance.
// If you need dynamic extensions, use React.useMemo to minimize reference changes
// which cause costly re-renders.
const extensions = [javascript()];

export default function App() {
  const editor = useRef();
  const { setContainer } = useCodeMirror({
    container: editor.current,
    extensions,
    value: code,
  });

  useEffect(() => {
    if (editor.current) {
      setContainer(editor.current);
    }
  }, [editor.current]);

  return <div ref={editor} />;
}

Using Theme

We have created a theme editor where you can define your own theme. We have also defined some themes ourselves, which can be installed and used directly. Below is a usage example:

import CodeMirror from '@uiw/react-codemirror';
import { javascript } from '@codemirror/lang-javascript';
import { okaidia } from '@uiw/codemirror-theme-okaidia';

const extensions = [javascript({ jsx: true })];

export default function App() {
  return (
    <CodeMirror
      value="console.log('hello world!');"
      height="200px"
      theme={okaidia}
      extensions={[javascript({ jsx: true })]}
    />
  );
}

Using custom theme

import CodeMirror from '@uiw/react-codemirror';
import { createTheme } from '@uiw/codemirror-themes';
import { javascript } from '@codemirror/lang-javascript';
import { tags as t } from '@lezer/highlight';

const myTheme = createTheme({
  theme: 'light',
  settings: {
    background: '#ffffff',
    foreground: '#75baff',
    caret: '#5d00ff',
    selection: '#036dd626',
    selectionMatch: '#036dd626',
    lineHighlight: '#8a91991a',
    gutterBackground: '#fff',
    gutterForeground: '#8a919966',
  },
  styles: [
    { tag: t.comment, color: '#787b8099' },
    { tag: t.variableName, color: '#0080ff' },
    { tag: [t.string, t.special(t.brace)], color: '#5c6166' },
    { tag: t.number, color: '#5c6166' },
    { tag: t.bool, color: '#5c6166' },
    { tag: t.null, color: '#5c6166' },
    { tag: t.keyword, color: '#5c6166' },
    { tag: t.operator, color: '#5c6166' },
    { tag: t.className, color: '#5c6166' },
    { tag: t.definition(t.typeName), color: '#5c6166' },
    { tag: t.typeName, color: '#5c6166' },
    { tag: t.angleBracket, color: '#5c6166' },
    { tag: t.tagName, color: '#5c6166' },
    { tag: t.attributeName, color: '#5c6166' },
  ],
});
const extensions = [javascript({ jsx: true })];

export default function App() {
  const onChange = React.useCallback((value, viewUpdate) => {
    console.log('value:', value);
  }, []);
  return (
    <CodeMirror
      value="console.log('hello world!');"
      height="200px"
      theme={myTheme}
      extensions={extensions}
      onChange={onChange}
    />
  );
}

Use initialState to restore state from JSON-serialized representation

CodeMirror allows to serialize editor state to JSON representation with toJSON function for persistency or other needs. This JSON representation can be later used to recreate ReactCodeMirror component with the same internal state.

For example, this is how undo history can be saved in the local storage, so that it remains after the page reloads

import CodeMirror from '@uiw/react-codemirror';
import { historyField } from '@codemirror/commands';

// When custom fields should be serialized, you can pass them in as an object mapping property names to fields.
// See [toJSON](https://codemirror.net/docs/ref/#state.EditorState.toJSON) documentation for more details
const stateFields = { history: historyField };

export function EditorWithInitialState() {
  const serializedState = localStorage.getItem('myEditorState');
  const value = localStorage.getItem('myValue') || '';

  return (
    <CodeMirror
      value={value}
      initialState={
        serializedState
          ? {
              json: JSON.parse(serializedState || ''),
              fields: stateFields,
            }
          : undefined
      }
      onChange={(value, viewUpdate) => {
        localStorage.setItem('myValue', value);

        const state = viewUpdate.state.toJSON(stateFields);
        localStorage.setItem('myEditorState', JSON.stringify(state));
      }}
    />
  );
}
