Attached is the latest snapshot of scripts and support classes
that I had used back then...
nodejs.bbclass does the main work of handling the recipes.
It supports usage of the same npm package with different
versions by adding appropriate symlinks for the file system
Also, it extracts the runtime depends from package.json (and
add runtime provides) so as to get proper dependency trees.
nodegyp.bbclass is for recipes that use node-gyp (or node-pre-gyp).
This needs node-gyp and gyp (as build tools). I didn't
create-recipe-from-json.py is the actual script, point it at a
package.json, and optional shrinkwrap. It does the other part of the
deduplication by keeping track of the dependency tree and adding the
appropriate symlink information to the recipes as understood by
nodejs.bbclass.
At the time I had a problem with runtime depends for native packages,
RDEPENDS for native packages wasn't implemented in OE back then.
I've commented out "DEPENDS_append_class-native" handling now,
as this should work without tricks these days.
node-pre-gyp support wasn't fully implemented in the create-recipe
script. npm-modules using node-gyp or node-pre-gyp did work fine and
can be cross-compiled without probllem, though.
Some npm-modules require extra handling, e.g. patches to be applied, this
is done in around line 205, where an extra 'require' line is added
to the generated recipe, I've also added nodejs-node-gyp.inc as an
example for what that could look like.
I didn't use recipetool, either cause I didn't know it back then, or it
wasn't available at the time.
It's very fast though. Most time is spent downloading the packages for
analysis...

Yes, but it is clever in the sense that deduplication is applied, including
looking
for matching version numbers as per the version specification.
