Analysis
The package's preinstall hook (node setup.mjs) downloads the Bun JavaScript runtime from github[.]com/oven-sh/bun/releases and then executes a 727KB heavily-obfuscated script (math_init.js) at install time. The obfuscated payload uses javascript-obfuscator-style string-array encoding and contains eval/Function/child_process calls, so its behaviour cannot be inspected statically. A Vue component library has no legitimate need to download a runtime and run an opaque obfuscated script during installation.
