# Application Hot Update

When developing Xiaomi Vela JS applications using AIoT-IDE, a built-in hot update feature is also included. When developers click the top action bar Run or Debug button to run the simulator, file changes are constantly monitored.

When file changes are detected, automatic compilation is triggered, the current project is pushed, and the latest effects of the compiled code can be previewed in real-time. When the Run or Debug button is clicked again to cancel the push, file monitoring will stop, reducing performance consumption.
