Furthermore, during code reviews, highlighting specific lines allows for clear communication and focused discussion.

Implementing Highlight Line Functionality in Monaco Editor

The Monaco editor provides several methods for highlighting lines. Let’s explore the most common and effective techniques:

• Using the deltaDecorations method: This powerful method allows for dynamic and flexible line highlighting. You can specify the line number and a CSS class to apply the desired styling.
• Leveraging the setDecorations method: This method is useful for setting static decorations, such as highlighting specific lines based on search results.
• Integrating with the theme: You can customize your Monaco editor theme to define specific styles for highlighted lines, ensuring consistency across your projects.

Example: Highlighting a Specific Line Using deltaDecorations

const editor = monaco.editor.create(document.getElementById('container'), {
  value: '// some code n console.log("Hello, world!"); n // more code',
  language: 'javascript'
});

const lineNumberToHighlight = 2;
const decorations = editor.deltaDecorations([], [{
  range: new monaco.Range(lineNumberToHighlight, 1, lineNumberToHighlight, 1),
  options: {
    isWholeLine: true,
    className: 'my-highlighted-line'
  }
}]);

This code snippet demonstrates how to highlight the second line of the editor using the deltaDecorations method. The my-highlighted-line class can then be styled in your CSS to achieve the desired visual effect. You can also explore options like remove highlight in style.
