We don't have a dev script as far as I can see. The start script starts the docs in dev mode as it calls docs:dev under the hood.

[Jay-Karia]

You have referred the package.json file in the root.
I am talking about the package.json file from docs/ directory, where there is dev and start scripts.

[Jay-Karia]

So we need to update the README of /docs directory.

So we need to update the README of /docs directory.

That README says to run it from the project root:

To start the docs site in development mode, from the project root, run:

It's confusing though. I'd probably just say pnpm docs:dev everywhere instead of pnpm start

[Jay-Karia]

Yeah,
It should be obvious to mention scripts in /docs README that would run in /docs directory instead in root.
This might reduce confusion.

At the end it's upto you.
Will respect your decision. 👍

I'm ok with recommending pnpm docs:dev instead of pnpm start from the root, but not with recommending running scripts from the docs folder. There is no good reason to run scripts in workspaces directly.

[Jay-Karia]

Now it's pnpm docs:dev

[Janpot]

Ok for me. The main problem with the pnpm start script is that it will try to run the docs site in production when run from the wrong folder. At least now the error will say "Command "docs:dev" not found" if run from the docs folder. Improved DX for first time contributors 👍
