Metadata

db.metadata.get returns read-only snapshots for metadata records. You can keep chaining filters or use normal array methods.

These examples use a small fixture that resets for every run. Your application still uses its own Realm database.

  .all()
  .map(item => ({
    title: item.Title,

return db.metadata.get
  .toArray()
  .map(item => ({

Returns the first matching metadata record, or undefined.

return db.metadata.get
  .first()?.Title
