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

[x] I have searched for similar issues
[x] I am using the latest version of npm-check-updates
[x] I am using node >= 14

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. [email protected] 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

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.

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

npx [email protected] --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 (#1182).
Running --deep will not trigger workspace support.

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",

@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.
