Is there a way to minify a file WITHIN a local module?

[YuLogun]

I have a custom Nuxt module that reads a local .js file and then passes it to a nitro plugin.

export default defineNuxtModule({
   async setup (options, nuxt) {
       const resolver = createResolver(import.meta.url)
       const scriptPath = await resolver.resolve('../helpers/visual-settings.js')
       const scriptText = await fsp.readFile(scriptPath, 'utf-8')

       nuxt.hook('nitro:config', (config) => {
           config.virtual = config.virtual || {}
           config.virtual['#visual-settings'] = `
                export const script = ${JSON.stringify(scriptText, null, 2)}
           `
       })
    }
})

Nitro plugin then adds it to HTML head
src/server/plugins/visualSettings.ts

export default defineNitroPlugin((nitroApp) => {
    nitroApp.hooks.hook('render:html', (html) => {
        html.head.push(`<script>${script}</script>`)
    })
})

The file is added to head as it is, unminified.
Is is possible to minify the file inside my module before passing it to nitro plugin?

I use cssnano with postcss in one of my modules.

const scriptText = '...';
const minifiedScriptText = await postcss([cssnano({ preset: 'default' })]).process(scriptText, {
  from: undefined,
});

I ended up with esbuild approach

export default defineNuxtModule({
  setup (options, nuxt) {
       nuxt.hook('nitro:config', async (config) => {
           config.virtual = config.virtual || {}
           let script = ''

           try {
               const resolver = createResolver(import.meta.url)
               const scriptPath = await resolver.resolve('../helpers/visual-settings.js')
               const scriptText = await fsp.readFile(scriptPath, 'utf-8')
               const scriptTransformed = await esbuild.transform(scriptText, {
                   minify: true,
                   format: 'iife',
                   target: 'es2020'
               })
               script = scriptTransformed?.code || ''
           } catch (error) {
               console.error('Error in Visual Settings module', error)
           }

           config.virtual['#visual-settings'] = `
                export const script = ${JSON.stringify(script, null, 2)}
           `
       })
    }
})
