ZSH function to auto-switch to correct Node version

# ZSH function to auto-switch to correct Node version
# https://gist.github.com/callumlocke/30990e247e52ab6ac1aa98e5f0e5bbf5
#
# - Searches up your directory tree for the closest .nvmrc, just like `nvm use` does.
#
# - If you are already on the right Node version, IT DOES NOTHING, AND PRINTS NOTHING.
#
# - Works correctly if your .nvmrc file contains something relaxed/generic,
# like "4" or "v12.0" or "stable".

How to run TypeScript CLI tasks in a Next.js app

Assuming you've got a Next.js app that's already using TypeScript to render pages/components or handle API routes, but you also want to be able to run ad hoc build tasks written in TypeScript (perhaps pulling in type files used by the app)...

  1. Add these deps: npm install -D @babel/core @babel/node
  2. Make sure your Next app has an explicit .babelrc file:
// Default Next.js .babelrc (it's OK if you also have extra stuff in it)
{
  "presets": ["next/babel"],
 "plugins": []
