node: schema prefixes on repl.it

If you want to use the node: prefixes for builtin modules on repl.it, then (as of May 2021) you need to do a few things:

1. In .replit, add the [packager] section with the ignoredPackages configuration seen in the example file below. This will disable the automatic installation on repl.it of these packages.
2. In .replit, change the start script to yarn start
3. In package.json, add a scripts section with the start script as seen in the example file below. This will transpile away the node: prefixes for the older Node v12 version using @upleveled/babel-plugin-remove-node-prefix.
4. Run yarn add --dev @babel/core @babel/node @upleveled/babel-plugin-remove-node-prefix

Example repl here: https://replit.com/@karlhorky/node-prefix-babel-demo#index.js

Methods of Signing with GPG

There are now two ways to approach this:

1. Using gpg and generating keys
2. Using Kryptonite by krypt.co

This Gist explains how to do this using gpg in a step-by-step fashion. Kryptonite is actually wickedly easy to use-but you will still need to follow the instructions

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing with either GPG or Krypt.co.
