Maybe the title is not very clear, I will explain in detail:

I rely on a jq component in a project. It is referenced through a script tag. How can I make it available through the import method?

https://www.npmjs.com/package/particles.js

This is the library above. I changed the part where I forgot to hang a function on the window to export default. I found that an error will be reported. How can I modify this so that I can use import?

window.particlesJS.load = function(tag_id, path_config_json, callback){
    code ...
}

//这里我加了

export defalut particlesJS;

I found that it is not possible. What did I do wrong?
