JavaScript

Ecosystem

By JavaScript, I mean the entire ecosystem including different runtimes, package managers and TypeScript.

Resources

• Web Spec
• Just JavaScript by Dan Abramov and Maggie Appleton (excellent quality)

Runtime Manager

note

More about runtimes.

My current favourite is Volta.

• Installing global versions of Node and add global dependencies.
• Pinning project versions of Node and Yarn to a project
  • The pinned version is stored package.json
  • Switching project directories automatically switches to the pinned runtime and package manager versions, which makes for a great experience 🚀

Most used commands

# Global
volta install node@lts
volta install <package>
volta list

# In projects
volta pin node@lts
volta pin yarn@latest
cat package.json

Package management

Tips and tricks for how to manage packages in practice.

I've been using Yarn. yarn is quick to type, plays well with other tools like Volta, and it has been progressively maintained over the years.

Description	Yarn
Update packages	yarn upgrade-interactive
Install a package globally	volta install <package> Note: (yarn global add never worked well across platforms) Note: (outside of a project folder when using volta)
Linking a dependency	volta install yalc yalc publish (in dependency root) yalc link (in project root)
