How to add close bracket and close tag for react code mirror

1.9k views Asked by Pranavan At 18 July 2021 at 09:41

I'm using react-codemirror2 in a react project. I want to add features like auto bracket close and auto tag close. There is a npm package called @codemirror/closebrackets but I can't find any documentation to do that.

        <ControlledEditor
            onBeforeChange={handleChange}
            value={value}
            className="code-mirror-wrapper"
            options={{
                linerWrapping: true,
                lint: true,
                mode: language,
                theme: 'material',
                lineNumbers: true
            }}
        />

This is my react component. Specify if there is a way to do without additional packages like @codemirror/closebrackets.

You can add autoCloseBrackets: true to your options and it'll work fine. From the doc:

Defines an option autoCloseBrackets that will auto-close brackets and quotes when typed.

import 'codemirror/addon/edit/closebrackets'

// other parts of the code//

<ControlledEditor
            onBeforeChange={handleChange}
            value={value}
            className="code-mirror-wrapper"
            options={{
                linerWrapping: true,
                lint: true,
                mode: language,
                theme: 'material',
                lineNumbers: true,
                autoCloseBrackets: true,
            }}
        />
