Installing npm packages from multiple registries

Question

Working on a project where I need to install npm packages from several registries - the default npm registry and several custom registries.

My existing solution is to use npm scripts to break the install into steps which use the --registry flag. Something like this:

"install-pkg1":   "npm install pkg1 --registry https://pkg1.domain.com",
"install-pkg2":   "npm install pkg2 --registry https://pkg2.domain.com",
"install-custom": "npm install && npm run install-pkg1 && npm run install-pkg2"

Then use npm run install-custom in place of npm install to install all the dependencies.

Is there a more preferred method for installing packages from multiple registries?

As noted in the comments below, there is a discussion on Github about this.

Answer 1

This is pretty much one of the reasons for npm ci. The registries and versions will be defined there so you shouldnt need to do anything crazy to get them all from their corresponding registries. Also, this can kind of be accomplished with scopes, where you associate a registry with a scope, but this requires you publishing the packages scoped as whatever. more info on associating registry with scopes
