How to install only production dependencies in modern yarn when using node-modules linker

Question

I'm using modern Yarn (v3.2.4 to be exact) which differs from Yarn Classic.

I'm using the nodeLinker: node-modules option in .yarnrc.yml so /node_modules are created, and dependencies are not saved to the repo.

I want to install only production dependencies (no devDependencies) but the --production flag isn't support in in Yarn 3. How can I do this?

You can use the yarn workspaces focus --production command. Check out the documentation here.

As user Bobby mentioned in the other answer, it is possible to install only production dependencies by using the Yarn Workspace plugin.

This requires that the plugn be installed first: yarn plugin import workspace-tools.

Then install with: yarn workspaces focus --production.
