# wx.setStorage(Object object)

Stores data in the specified key in the local cache. This operation will overwrite the original content of the key. The data storage lifecycle is consistent with the Mini Program, that is, data is always available unless manually deleted by the user or automatically deleted after a certain period of time. The maximum size of data stored in a single key is 1 MB, and the total size for data storage is limited to 10 MB.

# Parameters

# Object object

Attribute	Type	Required	Description
key	string	Yes	The specified key in the local cache
data	any	Yes	Contents to be stored can only be native types, dates, and objects that can be serialized via `JSON.stringify`.
success	function	No	The callback function for a successful API call
fail	function	No	Callback function for failed API call
complete	function	No	Callback function used when API call completed (always executed whether call succeeds or fails)

# Sample Code

wx.setStorage({
  key:"key",
  data:"value"
})

try {
  wx.setStorageSync('key', 'value')
} catch (e) { }
