How-to: Run npm/yarn with one command

As a person working with different people indifferent repos, mixing up npm with yarn and inconsistent script names to start the project really grinds my gears.

• Do I run npm install or yarn install?
• Did someone just add a package-lock.json to a yarn repo?
• Do I run yarn dev, yarn start, yarn start:dev or yarn start:all to fire up the dev server?
• Did linting/build/deployment just fail on CI because we use yarn there, but npm and package-lock in this repo?

1. Select yarn (or npm)

• Decide on using one of them (yarn for speed, and monorepo support).
• Remove and add the other lock file to .gitignore
• Make sure your CI scripts use the same package manager

2. Add a script for installing packages 🎀

Add the script below to your bash profile. This will alias ins to install packages in the current repo, using whatever .

3. Add a script for starting the app 🚀

Add the script below to your bash profile. This will alias sta to start the repo, with the commonly used dev script that the repo uses.
