如何导出 NPM 模块以在没有 package 名称的情况下使用它？

Question

I'm trying to export a NPM module to use it without package name.

This is the usual way to export module:

function hello(){
    console.log("hello");
}

module.exports.hello = hello;

And we use this like that:

const h = require("hello");

h.hello();

But I want to use it without h variable. So I want to use this module like that:

require("hello");

hello();

How can I export this module like it?

Of course, just expose your function on the global scope of your environment, this is window for the browser or global for node. If you're using a bundler like webpack, you can just use global , webpack will do the rest.

// hello.js

function hello() {
    console.log("hello");
}

window.hello = hello;

module.exports = hello;

// main.js

require("./hello");

hello(); // the same as `window.hello();`
