cursor-selection-handling

This codemod shows how to migrate cursor and selection handling from Slate v0.88 to v0.104, including the Preventing runtime errors from null selections.

Code Changes

Version 0.88

typescript
Copy
const selection = editor.selection;
const start = Range.start(selection);

Version 0.104

typescript
Copy
const selection = editor.selection as Range | null;

if (selection) {
  const start = Range.start(selection);
  // Selection is now safely typed and null-checked
}

Key Changes

• Added explicit type casting to Range | null
• Implemented null safety check using conditional block
• Ensures selection exists before accessing its properties

Migration Benefits

• Prevents runtime errors from null selections
• Provides better TypeScript type safety
• Follows current best practices for Slate selection handling
