JavaScript without npm?
A dive into Rails 7's importmap approach

Using JavaScript in Rails has a very long history. With Rails 7, the latest approach has been to move away from the tools from the JavaScript community like npm, yarn, and Webpack. Instead, Rails 7 introduces importmap-rails as a solution that “embraces the platform” and uses native JavaScript modules (also known as “ES Modules” or “ESM”).

What’s Importmap-rails?

Make WSL2 faster by removing /mnt/c in the PATH variable

Turning off appendWindowsPath (the feature that adds /mnt/c paths to $PATH) can make WSL faster.

For Ubuntu on WSL

For most distros, it can be done by editing /etc/wsl.conf. These instructions were taken from https://gist.github.com/ilbunilcho/4280bd55a10cefef75e74986b6bff936

$ sudo vi /etc/wsl.conf
