Methods

clear()

clear(): Promise<void>;

Source: undefined

Returns

Promise<void>

Implementation of

IStore.clear

close()

close(): Promise<void>;

Source: undefined

Close the store and cleans up this resource from memory. You should not call any method on this object anymore and should drop any reference to it.

Source: undefined

Removes a key-value pair from the store.

Parameters

entries()

entries<T>(): Promise<[string, T][]>;

Source: undefined

Returns a list of all entries in the store.

Type Parameters

Type Parameter

Parameters

Parameter	Type	Description
cb	(key, value) => void	-

Returns

Promise<UnlistenFn>

A promise resolving to a function to unlisten to the event.

Since

2.0.0

Implementation of

IStore.onChange

key	string	-
cb	(value) => void	-

Returns

Promise<UnlistenFn>

A promise resolving to a function to unlisten to the event.

Since

2.0.0

Implementation of

IStore.onKeyChange

reload()

reload(options?): Promise<void>;

Source: undefined

Attempts to load the on-disk state at the store’s path into memory.

This method is useful if the on-disk state was edited by the user and you want to synchronize the changes.

Note:

• This method loads the data and merges it with the current store, this behavior will be changed to resetting to default first and then merging with the on-disk state in v3, to fully match the store with the on-disk state, set ignoreDefaults to true
• This method does not emit change events.

Parameters

Parameter	Type
options?	ReloadOptions

Returns

Promise<void>

Implementation of

IStore.reload

reset()

reset(): Promise<void>;

Source: undefined

Resets the store to its default value.

If no default value has been set, this method behaves identical to clear.

Returns

Promise<void>

Implementation of

IStore.reset

save()

save(): Promise<void>;

Source: undefined

Saves the store to disk at the store’s path.

Returns

Promise<void>

Implementation of

IStore.save

set()

set(key, value): Promise<void>;

Source: undefined

Inserts a key-value pair into the store.

Parameters

Parameter	Type	Description
key	string	-
value	unknown	-

Returns

Promise<void>

Implementation of

IStore.set

values()

values<T>(): Promise<T[]>;

Source: undefined
