Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

GitHub Pages is great for building a personal or project website. It'll default to http://username.github.io, or you can even use your own custom domain name from services like Namecheap, which I will write about in another post soon.

So you set up your GitHub Page for yourself or project, but what if you want to show off some of your other projects you are working on. You can go the poor man's route, and simply just copy everything from another repository into a folder in your username.github.io repository, commit and push the changes to GitHub, and you'll be able to navigate to http://username.github.io/project.

But this comes with some seriously inconvienent and non-conventional drawbacks, such as duplication of code across repositories and manually copy/paste-ing everytime changes are made to update your hosted codebase. Good luck maintaining that.
