Apple M1 workaround for Docker

Prerequisites

You need a dedicated Linux machine (linux-vm) (in the cloud or on your VPS, or bare-metal) with Docker installed and SSH enabled (required login using SSH keys).

Workaround for people who have SSH access to a docker installed linux machine

Install go (pre-compiled binaries at https://golang.org/dl/

(Edit: there are no Darwin arm64 yet, You need to compile or use Homebrew...)

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.

Element

Box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
• elem.clientLeft, elem.clientTop, elem.clientWidth, elem.clientHeight
• elem.getClientRects(), elem.getBoundingClientRect()
