[Map] NPM install does not working due to workspace url type

[dannyvw]

In https://github.com/symfony/ux/blob/2.x/src/Map/src/Bridge/Leaflet/assets/package.json#L52 is added "workspace:" url type added but NPM does not recognise this type. Error: npm error Unsupported URL Type "workspace:": workspace:

package.json

"@symfony/ux-leaflet-map": "file:vendor/symfony/ux-leaflet-map/assets",

Works "@symfony/ux-leaflet-map": "2.24"

I was able to reproduce it with the following reproducer:

sf new sf-ux-2737 
cd sf-ux-2737
npm init
composer require symfony/ux-map symfony/ux-leaflet-map
npm i

npm error code EUNSUPPORTEDPROTOCOL
npm error Unsupported URL Type "workspace:": workspace:*
npm error A complete log of this run can be found in: /Users/kocal/.npm/_logs/2025-05-14T13_23_55_268Z-debug-0.log

I didn't expect npm to "read" these dev dependencies since they are not supposed to be installed when installing @symfony/ux-map... 🤔

I believe we can modify the npm packages release process to replace workspace:* by the actual version...

Fixed with 2.25.0, but first remove the package so you can re-install it

@Kocal Not sure if it is fixed. With the new release the problem still exists when using the next reference in package.json "@symfony/ux-leaflet-map": "file:vendor/symfony/ux-leaflet-map/assets",. I think this is because in the composer vendor package the workspace option still exists.

When using a version ("@symfony/ux-leaflet-map": "~2.25.1") from npm it works.

My bad I think I read your first message too quickly.

Unfortunately, I don't think @symfony/ux-leaflet-map with file:vendor/symfony/ux-leaflet-map/assets will ever be compatible with npm, unless we find a workaround.

The workspace:* things help Yarn (that we use in symfony/ux) to manage our workspaces, dependencies, and the topological order when running yarn workspaces foreach ....

To make @symfony/ux-leaflet-map from file:vendor/symfony/ux-leaflet-map/assets compatible with NPM, it means that we must modify the src/Map/Bridge/Leaflet/assets/package.json from the repository, and commit it. But since Composer install packages from archives/source code from GitHub, that's not possible. Unlike NPM, where we already fix the constraint version before publishing the package on NPM.

I understand that's annoying, and making npm - the default JS package manager - fails, because it's unable to ignore unknown protocol workspace: is a shame, can't npm ignore it?

If you have a better alternative for Symfony UX repository, I'm all ears, but for the moment I can only suggest you to use a more-modern and efficient packages manager like PNPM or Yarn. 🙏🏻

@Kocal Thanks for your message. PNPM is on my list for testing, but currently I don't have time for that. Will try it definitely.
