Learning yarn
Just one of the things I'm learning. https://github.com/hchiam/learning
yarn is like npm, but better (in my opinion).
If you're already using npm, there's a very minimal migration and learning curve.
How yarn relates to npm: https://www.sitepoint.com/yarn-vs-npm/ (from 2016)

- Concurrency for faster installations.
- Exact installed versions recorded by default.
- Checksums before executing packages.
- Can work offline for packages you've installed before.
- Less verbose CLI install messages.
- A minor downside: older npm packages may not work or be installable.
Install yarn: https://yarnpkg.com/en/docs/install
Example commands
Setup deps
yarn init = npm init
yarn or yarn add = npm install
(You can use yarn import to generate a yarn.lock file from an existing package-lock.json)
Install package as dep, dev dep, or globally
yarn add <...> = npm install <...> --save
yarn add <...> --dev = npm install <...> --save-dev
yarn global add <...> = npm -g install <...>
- WARNING: it's
global addand NOTadd global(yarn add globalinstalls a package literally namedglobal).
Install package without dynamic version (i.e. without caret ^)
yarn add <package-name> --exact = npm install <package-name> --save-exact
so you get 1.2.3 instead of ^1.2.3 in your package.json
Uninstall package
yarn remove <...> = npm uninstall <...> --save
Upgrade package version
yarn upgrade <...> = npm update <...> --save
Common commands you might use/customize
yarn test = yarn run test = npm run test
yarn build = yarn run build = npm run build
yarn start = yarn run start = npm run start
Other stuff
yarn why = dependency graph and helps you see if you explicitly added a package
yarn licenses (no npm equivalent)
yarn upgrade --latest = upgrade dependencies while ignoring the version range specified in package.json (could help with security updates) (reminds me of npm audit fix
yarn global list = check what's been globally installed with yarn
