react-native-bg-thread
This package helps in executing the javascript in a background thread. Time-consuming javascript code is shifted to a native background thread by freeing the main-UI thread, which helps in increasing the efficiency of the application. Thread priority can be handled by passing in the appropriate flags. Currently we support three types of flag as under:
| Priority Flags | Description | Android thread value | IOS thread value |
|---|---|---|---|
| MAX | This sets the thread priority to the maximum available on the corresponding native platform. | 10 | 1.0 |
| MIN | This sets the thread priority to the minmimum available on the corresponding native platform. | 1 | 0.1 |
| NORMAL | This sets the thread priority to the default or normal on the corresponding native platform. | 5 | 0.5 |
