Pebble.Storage

Watch-local key/value storage commands.

The watch runtime exposes a lightweight integer- and string-keyed store. Keys are integers; values can be ints or strings. Use maxSize to learn the per-app byte limit on the current firmware.

import Pebble.Storage as Storage

storageKey : Int
storageKey =
    1

type Msg
    = CounterLoaded Int
    | MaxSizeLoaded Int

init _ =
    ( model
    , Cmd.batch
        [ Storage.readInt storageKey CounterLoaded
        , Storage.maxSize MaxSizeLoaded
        ]
    )

saveCounter : Int -> Cmd msg
saveCounter value =
    Storage.writeInt storageKey value

For a runnable example, use the watch-demo-storage project template in the IDE.
