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 🙏

Differences with webpack5

module-federation/webpack-4The plugin has implemented the main capabilities of module-federation, and can be found in webpack4 and webpack5 refer to each other , The following describes which parameters are not supported by the plugin

unsupported parameter

options.library

The priority of this parameter is not very high, the implementation in webpack4 is more complicated, and there are still problems in using it in webpack5, see for details "https://github.com/webpack/webpack/issues/16236" , Therefore, the implementation in webpack4 is similar to setting library.type = "global"

options.remotes.xxx.shareScope

The same mf container can only be initialized with one shareScope. If inconsistent webpack is set by using shareScope multiple times, it will report an error, and the shareScope can be set too much, which is confusing. Even in pure webpack5, the performance is unpredictable. It is recommended to use options. shared.xxx.shareScope, options.shareScope alternative

module-federation ecological package

The webpack-4 plugin has not yet integrated the ability of webpack-5 related packages(ssr、typescript、hmr、dashboard...), However, 4 and 5 interoperability has been achieved, which can help you to use webpack5 to implement new projects without refactoring existing projects.
