# SetSharedOptions

`module:balena-sdk~setSharedOptions(options)`

Set options that are used by calls to `fromSharedOptions()`. The options accepted are the same as those used in the main SDK factory function. If you use this method, it should be called as soon as possible during app startup and before any calls to `fromSharedOptions()` are made.

**Kind**: inner function\
**Summary**: Set shared default options\
**Access**: public
