rm -rf node_modules && npm install is the same as doing npm ci.

[Haroenv]

What about leaving it as two lines?

[Haroenv]

With package-lock.json it’s more equivalent to just “yarn” though

[dotnetCarpenter]

@Haroenv I'm sorry, maybe I don't fully understand what yarn upgrade do.

To be clear, npm ci will:

1. nuke the node_modules folder - same as rm -rf node_modules
2. install exact versions as described in package-lock.json.

If I understand you correctly, then yarn is the same as npm ci and yarn upgrade is the same as npm install.

[Haroenv]

Upgrade would be the same as removing the lock file on npm and running npm install again yes, this situation changed since Yarn was first released
