Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

rollup-tag-test

v1.0.1

Published

利用 Rollup 实现一个可以同时使用ES Module 和 CommonJS 导入的工具包

Readme

利用 rollup 自动编译 ES Module 和 CommonJS 两种包导入方式

测试案例

通过 npm 下载该包:

不设置 type 时,使用 require 导入函数并成功调用。

// 测试 commonjs 
const { test, test2 } = require("rollup-tag-test");
const { hello } = require("rollup-tag-test/util");

test(); // test 111 ===>
test2(); // 222 ===>
hello(); // a ===> { name: 'chiko', age: 12 } chiko 12

设置 type 为 module时,使用 import 导入函数并成功调用。

// 测试 es module
import { test, test2 } from "rollup-tag-test";
import { hello } from "rollup-tag-test/util";

test(); // test 111 ===>
test2(); // 222 ===>
hello(); // a ===> { name: 'chiko', age: 12 } chiko 12

总结

当 package.json 中的 type 等于 module 时, 说明当前的项目导入方式以 ES Module 为主。 此时使用 ES Module 模块时,后缀直接指定为 .js 即可。 但是使用 CommonJS 的模块时,后缀必须指定为 .cjs 才能运行。 反过来也一样, 当不指定 type 时,默认以 CommonJS 为主,使用 Commonjs 模块时后缀可以直接省略,但是使用 ES Module 的模块时,后缀必须指定为 .mjs 才能运行。
