assetValidator • tldraw Docs

Validator for TLAsset records that ensures runtime type safety. Uses a discriminated union based on the 'type' field to validate different asset types.

assetValidator: T.Validator<TLAsset>

Example

// Validation happens automatically when assets are stored
try {
  const validatedAsset = assetValidator.validate(assetData)
  store.put([validatedAsset])
} catch (error) {
  console.error('Asset validation failed:', error.message)
}
