issue disable tree-shaking and change variable and function name

Describe the bug

Hi, I'm using Laravel 10 framework. after I run 'npm run build' command, all file compiled and minified but the problem is some my function or variable is deleted in compiled file so in console of browser i'will got 'Uncaught ReferenceError' think because of tree-shaking. also my name of functions will be changed. but in html document I've use the function name for example onchange="change data()" in select box. but the compiled file change the function to 'd' or something else; how can i prevent vite from remove my js function and changing name.
