pnpm vs npm vs yarn

Why pnpm?

npm takes lots of space on the local machine, mine just 15GB space for 100+ React/Node projects and also takes a lot of time to install.

Solution

pnpm solves this by installing packages in a central location .pnpm-store instead of the local folder of your project.

Advantages

1. Fewer spaces - 500MB node_modules takes only 14MB space
2. Faster - npm takes about 1.5 minutes to install a package, pnpm takes about 10+ seconds
3. Easy to migrate - no special setup needed - commands are very similar to yarn

It is effective when the same packages are used in many projects

Result

I have saved space up to 42 times

Migration guide

1. Using npm itself 😏 - npm install -g pnpm
2. Delete node_modules & package-lock.json
3. pnpm install

Additional tips

1. npx ➡ pnpx
2. npm install react ➡ pnpm add react (just like yarn)
