How to make binary available to all workspaces?

[xaviergmail]

I have a yarn workspace which specifes

  "dependencies": {
    "serverless": "^3.38.0",
    ...
  },
  "workspaces": [
    "sample-workspace",
    ...
  ]

I then have a deploy script in sample-workspace/package.json:

    "deploy": "serverless deploy ... && serverless deploy ..."

Running yarn deploy inside sample-workspace/ doesn't work.

I can run yarn exec serverless from the root of my repo. However, if I cd into sample-workspace and try to run yarn exec serverless, it can't find the serverless executable installed in the root of the repo either. I assumed this would work.

I have already read How to share scripts between workspaces? and none of those solutions are appealing to me.

We have several workspaces and we used to define the serverless dependency in each workspace's devDependencies. I just wanted to hoist that to the root workspace to make it easier to maintain. I'm not interested in having a script to maintain each package.json.

Things I've tried that didn't work:

• setting top-level serverless dependency as a runtime dependency instead of devDependency
• adding "serverless": "*" as a peerDependency in child workspaces

Things I've already tried that work:

• installing serverless globally npm i -g serverless works but my team doesn't like that even though serverless uses the locally installed serverless just fine
• changing the scripts to use npx serverless - this is a tad bit slower

At this point, we're basically only using yarn as a task runner (don't get me started 😂) and my only goal is to avoid having to specify serverless versions in each subproject. Is there another way to make the top-level-only dependency work with child workspace scripts and/or yarn exec without cluttering scripts with npx?

As the documentation you linked to says; you'll have to use yarn run -T serverless in your scripts to explicitly use the binary from the root workspace.
