I need to add a full Javascript code editor on my React App, which is using React Boilerplate and Dandelion template. I have installed react-codemirror2 as instructed on https://www.npmjs.com/package/react-codemirror2. I have this component:
import React from 'react';
import { Controlled as CodeMirror } from 'react-codemirror2';
import 'codemirror/lib/codemirror.css';
import 'codemirror/theme/material.css';
import 'codemirror/mode/javascript/javascript';
import 'codemirror/addon/hint/show-hint';
import 'codemirror/addon/hint/javascript-hint';
import 'codemirror/addon/hint/show-hint.css';
import 'codemirror/addon/hint/anyword-hint';
import 'codemirror/keymap/sublime';
import 'codemirror/addon/edit/closebrackets';
import 'codemirror/addon/edit/closetag';
import 'codemirror/addon/fold/foldcode';
import 'codemirror/addon/fold/foldgutter';
import 'codemirror/addon/fold/brace-fold';
import 'codemirror/addon/fold/comment-fold';
import 'codemirror/addon/fold/foldgutter.css';
function CodeEditor() {
const [code, setCode] = React.useState('// my code goes here');
return (
<CodeMirror
value={code}
options={{
mode: 'javascript',
lineWrapping: true,
smartIndent: true,
lineNumbers: true,
foldGutter: true,
gutters: ['CodeMirror-linenumbers', 'CodeMirror-foldgutter'],
autoCloseTags: true,
keyMap: 'sublime',
matchBrackets: true,
autoCloseBrackets: true,
extraKeys: {
'Ctrl-Space': 'autocomplete'
}
}}
onBeforeChange={(editor, data, value) => {
setCode(value);
}}
onChange={(editor, data, value) => {}}
/>
);
}
export default CodeEditor;
which is the same as in https://codesandbox.io/s/clever-shape-20y39?file=/src/App.js, but, in the sandbox the autocomplete shows up, and the same code snippet does not shows the autocomplete in the react app. What am I missing here?
