useMongocampIndex

Wraps indexApi for MongoDB index management — used by MongocampCollectionInfos's Indexes card.

const {
  listIndexes,         // (collectionName: string) => Promise<MongoIndex[]>
  createIndex,          // (collectionName: string, keys: Record<string, number>, options?: IndexOptionsRequest) => Promise<IndexCreateResponse>
  createUniqueIndex,     // (collectionName: string, fieldName: string, sortAscending?: boolean) => Promise<IndexCreateResponse>
  createTextIndex,       // (collectionName: string, fieldName: string) => Promise<IndexCreateResponse>
  createExpiringIndex,   // (collectionName: string, fieldName: string, duration: string) => Promise<IndexCreateResponse>
  deleteIndex,           // (collectionName: string, indexName: string) => Promise<IndexDropResponse>
} = useMongocampIndex()

Request shapes differ per creator

createIndex is the general-purpose compound-key creator — keys/options are nested under indexCreateRequest on the wire:

await createIndex('users', { email: 1 }, { unique: true })
// → indexApi.createIndex({ collectionName, indexCreateRequest: { keys: { email: 1 }, indexOptionsRequest: { unique: true } } })

createUniqueIndex/createTextIndex/createExpiringIndex are single-field convenience creators with flat parameters (no nested request object) — don't assume they share createIndex's shape:

await createUniqueIndex('users', 'email', false)   // sortAscending, not a keys map
await createTextIndex('users', 'name')
await createExpiringIndex('sessions', 'createdAt', '3600s')

MongoIndex.keys vs the create request's keys

The read model (MongoIndex.keys) is Record<string, string>; the create request's keys is Record<string, number> (sort direction 1/-1). They are not symmetric — don't reuse a fetched index's keys value directly as input to createIndex.

Deleting the default index

MongoDB won't let you drop the _id_ index — deleteIndex will just return an error for it. MongocampCollectionInfos filters it out of the deletable rows client-side rather than relying on the API call to fail gracefully.
