# Packaging Applications
The packaging of Xiaomi Vela JS applications
employs a specialized .rpk file format. In AIoT-IDE
, we provide two buttons, Package and Publish, in the top operation bar for packaging the project, as shown in Labels 1 and 2 in the following figure.
Simply click on "Package Application" to execute the packaging in the function panel. Upon successful packaging, a debug package will be generated in the dist directory.
The debug package is designed to facilitate developers' debugging efforts, so it does not undergo extensive optimization. Typically, the debug package includes debugging information to assist developers in debugging and locating errors.
