issue with vite while copiling

when i build with vite command ('npm run build') some of my functions are removed because vite use shaking tree and remove unnecessary functions and variables in js file. but they are used by elements which are created by js in the document. how can i prevent vite from removing my function and variable during compiling in JS files

You can use the keepAlive option in your vite.config.js file to prevent Vite from removing specific functions or variables during the build process.

Here's an example of how to use it:

// vite.config.js

export default {
  build: {
    rollupOptions: {
      output: {
        // Add the names of the functions or variables you want to keep
        // separated by commas
        keepAlive: ['myFunction', 'myVariable']
      }
    }
  }
}

In this example, myFunction and myVariable will not be removed by Vite during the build process.

Note that using keepAlive can increase the size of your final build, so only use it for functions or variables that are necessary for your application to function properly.
