Js package managers

Package Managers

npm

comes with node

yarn

• Facebook created yarn because npm was slow

pnpm

• uses symbolic links and caching
  • every dependency is installed once
    • ~/.pnpm-store/
• if two dependencies (or nested dependencies) have the same grand dependencies,
  • they can just point to the same package
  • no need to install it twice!
• drop in replacement for npm
• pnpm patch | pnpm
  • modify the source code of your dependencies

What is package hoisting????

Workspaces

workspaces | npm Docs

aka managing multiple repos in a single repo

• aka monorepo

Avoid manually using npm link

Introduced in npm v7

Why are pnpm workspaces better?

Workspace | pnpm

• built-in support for monorepos
• don't technically need

At Forma, we had a package

{
  "dependencies": {
    "forma-package": "workspace:*"
  }
}

Direct link to the package directory in the monorepo if you look at the pnpm-lock.yaml
