and I ran into an issue. NPM projects can have multiple dependencies on a single
package, and sometimes with multiple versions. NPM will manage this by creating
sub 'node_modules' tree.
Here is an example with a newly created angular application. The app depends on
3 different version of 'ansi-regex'. NPM will install the packages this way:
node_modules/ansi-regex @ 2.1.1
node_modules/cliui/node_modules/ansi-regex @ 3.0.0
node_modules/inquirer/node_modules/ansi-regex @ 4.1.0
node_modules/string-width/node_modules/ansi-regex @ 3.0.0
node_modules/@angular/compiler-cli/node_modules/ansi-regex @ 4.1.0
I use symbolic links instead of folders, append the major version to the
folder name and move the folders into the main node_modules folder. At
the moment I use one version per major version or first version unequal
to zero:
node_modules/ansi-regex-2
node_modules/ansi-regex-3
node_modules/ansi-regex-4
node_modules/cliui-X/node_modules/ansi-regex -> ../../ansi-regex-3
node_modules/inquirer-X/node_modules/ansi-regex -> ../../ansi-regex-3
node_modules/string-width-X/node_modules/ansi-regex -> ../../ansi-regex-3
node_modules/@angular/compiler-cli-X/node_modules/ansi-regex ->
../../../ansi-regex-4
node_modules/abc-X/node_modules/ansi-regex -> ../../ansi-regex-2
node_modules/abc-X/node_modules/cliui -> ../../cliui-X
node_modules/abc-X/node_modules/inquirer -> ../../inquirer-X
node_modules/abc-X/node_modules/string-width -> ../../string-width
node_modules/abc-X/node_modules/@angular/compiler-cli ->
../../../@angular/compiler-cli-X
How can you handle that with Yocto ? I am not sure but I think it is not
possible.
It is possible and Yocto could do even more. If you take a look at the
package ansi-regex you realize that the project increase the major
version only because they change the minimum required nodejs version.
This means you could replace all ansi-regex version by the last version,
add some symbolic links to the ansi-regex package and provide all
versions by the same package.

Stefan
