Methods

Methods

createIndex

  • createIndex(__namedParameters: { jsonPointer: string; keyPrefix: undefined | string; name: string }): Promise<void>

  • Creates a persistent secondary index in Replicache which can be used with scan.

    If the named index already exists with the same definition this returns success immediately. If the named index already exists, but with a different definition an error is returned.

    Parameters

    • __namedParameters: { jsonPointer: string; keyPrefix: undefined | string; name: string }
      • jsonPointer: string
      • keyPrefix: undefined | string
      • name: string

    Returns Promise<void>

del

  • del(key: string): Promise<boolean>

  • Removes a key and its value from the database. Returns true if there was a key to remove.

    Parameters

    • key: string

    Returns Promise<boolean>

dropIndex

  • dropIndex(name: string): Promise<void>

get

  • get(key: string): Promise<JSONValue | undefined>

  • Get a single value from the database. If the key is not present this returns undefined.

    Parameters

    • key: string

    Returns Promise<JSONValue | undefined>

has

  • has(key: string): Promise<boolean>

put

  • put(key: string, value: JSONValue | ToJSON): Promise<void>

  • Sets a single value in the database. The value will be encoded using JSON.stringify.

    Parameters

    • key: string
    • value: JSONValue | ToJSON

    Returns Promise<void>

scan

  • Gets many values from the database. This returns a ScanResult which implements AsyncIterable. It also has methods to iterate over the keys and entries.

    If options has an indexName, then this does a scan over an index with that name. A scan over an index uses a tuple for the key consisting of [secondary: string, primary: string].

    If the ScanResult is used after the ReadTransaction has been closed it will throw a TransactionClosedError.

    Type parameters

    Parameters

    • Optional options: O

    Returns ScanResult<K>

scanAll

  • scanAll<O, K>(options?: O): Promise<[][]>
