NPM-to-Yarn Cheatsheet, cribbed from shift.infinite.red

npm-yarn-cheatsheet.md

NPM -> Yarn

TL;DR

• yarn does npm install

• yarn add foo does npm install foo --save
• and for global installs: yarn global add foo is the same as npm install foo --global

(this was cribbed from here, switched around a little, and will probably become out-dated quite quickly; yarn docs can be found here)

What you need to know

• npm install === yarn //Install is the default behavior
• npm install taco --save === yarn add taco //taco package is saved to your package.json
• npm uninstall taco --save === yarn remove taco //—-save can be defaulted in NPM by npm config set save true but this is non-obvious to most developers. Adding and * removing from package.json is default in Yarn.
• npm install taco --save-dev === yarn add taco --dev
• npm update --save === yarn upgrade //Great call on upgrade vs update, since that is exactly what it is doing! Version number moves, upgrade is happening! WARNING npm update --save seems to be kinda broken in 3.11
• npm install taco@latest --save === yarn add taco
• npm install taco --global === yarn global add taco //As always, use global flag with care. (Note: global always precedes add, bin, ls, remove, etc)

What you already know about yarn

The packages are the same as on the NPM registry. Yarn is basically a new installer, where NPM structure and registry * is the same.

• npm init === yarn init
• npm ls === yarn ls
• npm link === yarn link
• npm outdated === yarn outdated
• npm publish === yarn publish
• npm run === yarn run
• npm cache clean === yarn cache clean
• npm login === yarn login (and logout)
• npm test === yarn test

Things yarn has that NPM doesn’t

(yarn clean is warned against, but is there. It's run on yarn anyway, though.)

• yarn licenses ls  //Allows you to inspect the licenses of your dependencies
• yarn licenses generate  // Automatically create your license dependency disclaimer
• yarn why taco  // Identify why taco package is installed, detailing which other packages depend upon it
• 🐟 Emojis 🐸
• Speed 🏃⌁
• Automatic shrinkwrap with the yarn lockfile
• Security-centric design

Things NPM has that yarn doesn’t 😭

• npm xmas === **NO EQUIVALENT**
• npm visnup === **NO EQUIVALENT**

I considered turning it into a table. Would that be preferred?
