IDE

What's the maximum size of the mini program when uploading mini programs from IDE to the mini program platform?

The maximum size limit at the server side is 8MB. However, it's difficult to define the size limit of the source code because many factors impact the size of the packaged source code, such as image compressing. Currently the package for debugging on real devices has the maximum size. The file is stored in the directory as highlighted in the following figure.
