build JS script

path_js_entry_script is the location of the “entry” script in your project root

• e.g. the path to some index.js file, perhaps alongside a package.json file and node_modules directory

NOTES:

• disables “environment variable injection” for enhanced security and predictability
• assume a single entry point that generates a single build artifact
• you can pass in custom build options that will override the defaults

const async_build_js_script = async function (path_js_entry_script, build_options) {
	const result = await Bun.build({
		entrypoints: [ path_js_entry_script ],
		env: 'disable',
		minify: false,
		...build_options,
	})
	const str_out = await result.outputs[0].text()
	return str_out
}
