LiveCodes provides extensive configuration options for the code editor, allowing you to customize the editing experience to match your preferences.

​
Editor Selection

​
editor
"monaco" | "codemirror" | "codejar" | "auto" | undefined
default:"undefined"
Selects which code editor to use.
  • undefined (default): Smart selection based on context
    • Monaco on desktop
    • CodeMirror on mobile
    • CodeJar in lite/readonly/codeblock modes
  • "auto": Monaco on desktop, CodeMirror on mobile (ignores mode)
  • "monaco": Always use Monaco editor (VS Code editor)
  • "codemirror": Always use CodeMirror 6
  • "codejar": Always use CodeJar (lightweight editor)
const config = {
  editor: 'monaco',
  // ... other settings
};
Monaco provides the richest features but is larger. CodeMirror is lighter and mobile-friendly. CodeJar is the most lightweight option.
