[BUG] workspace scripts should be run in topological order by default

[justinfagnani]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

when running a script across workspaces like npm run build --workspaces you'll most likely end up with errors if your workspaces depend on each other as npm doesn't execute the script in topological order. Other monorepo tools like Lerna do this automatically.

The only workaround is to not use "workspaces": ["packages/*"] in package.json, but manually enter and maintain the list of packages by hand.

Expected Behavior

Scripts should run in topological order.

Steps To Reproduce

1. In any environment...
2. With a config that has multiple workspaces and wildcard workspaces setting like "workspaces": ["packages/*"], and one package that depends on another, and say both use TypeScript...
3. Run npm run build --workspaces
4. See error from the compiler

Environment

• npm: 8.2.0
• Node: 16.9.1
• OS: macOS 12.0.1
• platform: macOS
• npm config:

legacy-peer-deps = true

Just leaving a comment to link this to #3413 which is a related issue I think.

Hi @justinfagnani thanks for taking the time to bring this up to our attention.

Given that this would be an entire new feature for npm workspaces to support I would recommend you to propose this as either a issue or discussion over at our RFC repo where it can pick up the attention from the community and the rest of the npm cli team.

Sorry, I don't really have time to do that. This is how other monorepo tools work though, so if you want to just copy, say Lerna, that would probably be great for your users.
