Yarn is a cli-based package manager developed by Facebook. You can install it by using npm, which is kind of comical when you think about it:
 

npm i -g yarn

Here are a bunch of how-to scripts to handle common situations:

Install

Install all items within the package.json or install an individual package into the npm repo.


-- installs anything in the package.json
yarn install

-- installs a new package
yarn add antd
yarn add [email protected]
yarn add [email protected]

-- add to devDependencies
yarn add -D 

-- install from a github repo
yarn add [email protected]:owner/repo

-- install a global package
yarn global add 

Usage

Once it's installed, you can run the program by using:

yarn run

You can run a specific command in the package.json file by using:
 

yarn 
yarn build

Outdated

Find packages that are outdated.  This will display a list of available updates with the option of updating.

yarn upgrade-interactive
yarn upgrade-interactive -- latest

List Packages

List all of the installed packages…this is the same as just looking in the package.json file
 

yarn list

Other Helpful Commands
