ncu -i should execute npm install just once in a workspace.

• I am using the latest version of npm-check-updates

Steps to Reproduce

• node v16.15.1
• npm v8.11.0

Create the following structure:

├── package.json
└── packages
    ├── a
    │   └── package.json
    └── b
        └── package.json

root package.json:

{
  "name": "ncu-bug",
  "workspaces": [
    "packages/**"
  ]
}

• Install e.g. vanillajs@1.0.0 in "a" as well as in "b".
• Run ncu -i -deep in ncu-bug
• Accept every change
• Chhose "yes" if it asks to install.

Current Behavior

No dependencies.

Expected Behavior

It should run npm install only once in a workspace.

I am also running into this, and as a quick fix it would be nice if a CLI option was available to avoid the auto-install prompt altogether. This way I can add a package.json script with something like this: npm-check-updates --deep --interactive --noInstall && npm install (note the imaginary --noInstall option). In the long term though, it would definitely be nice to have workspaces detected and the install command to work correctly so that I don't need to add the && npm install command myself.

It should run npm install only once in a workspace.

@ghdoergeloh Is this literally just run npm install in the root project? Just want to confirm, as I haven't used workspaces yet myself.

[raineorshine]

Workspace support added in prerelease v16.2.0-0. Open for feedback :). Your help is much appreciated in finding unidentified edge cases.

npx npm-check-updates@v16.2.0-0 --workspaces

How it works

UPDATED 2023-09-23

Upgrade all workspaces:

ncu --workspaces
ncu -ws

Upgrade a single workspace:

ncu --workspace a
ncu -w a

Upgrade more than one workspace:

ncu --workspace a --workspace b
ncu -w a -w b

Upgrade all workspaces AND the root project:

ncu --workspaces --root

Upgrade a single workspace AND the root project:

ncu --workspace a --root

Notes

• If run in --interactive mode, ncu will prompt to npm install once in the root project rather than separately in each workspace (ncu -i should execute npm install just once in a workspace. #1182).
• Running --deep will not trigger workspace support.

[sunnysingh]

Wow you work fast @raineorshine! This worked well for me, I confirmed that --workspaces does not upgrade the root project, and --withWorkspaces does. It seems to only run npm install within the root project, but I didn't do any extensive testing here. I will keep using the prerelease version and report back if I happen to come across any issues.

I have been using this with seemingly no problems, can I expect different behavior with the new support, and thanks!

    "update": "ncu -u -i",
    "update:workspaces": "npm exec --workspaces -- ncu -u -i",

[raineorshine]

@httpete The only difference is the auto npm install in interactive mode.

• npm exec --workspaces -- ncu -u -i prompts to run npm install after each workspace is upgraded (i.e. once for each workspace).
• npm --workspaces -i upgrades each workspace and then prompts once at the end to run npm install in the project root.

The end result appears to be the same.

Published to latest on v16.3.0.

Note that --withWorkspaces has changed to a cleaner syntax of --workspaces --root (and --withWorkspace to --workspace X --root). Thanks to @mesqueeb for the suggestion.

But it not working in v16.3.2.

[mesqueeb]

@raineorshine FYI -ws is shorthand for --workspaces, maybe you didn't enable this flag on the NCU side?

[raineorshine]

Flags are enabled and working as expected.

[apetta]

Is there a way to run on all except a select few workspaces when using -ws?

[raineorshine]

No, they would have to be specified explicitly with -w.
