I naively tried

Is there any actual package example?  The anchor does not exist (any
more) on that wiki page (which should be updated to Salsa anyway ;-) ).

Kind regards

 Andreas.

Andreas, I get 404 errors when accessing all the links you supply for the 
project:
https://salsa.debian.org/r-pkg-team/r-cran-jsonld/

When you create a project on salsa, you can set the Visibility Level:
- Private: Project access must be granted explicitly to each user.
- Internal: The project can be accessed by any logged in user.
- Public: The project can be accessed without any authentication. 

I usually set it to "Public".

Maybe the project r-pkg-team/r-cran-jsonld/ has tight setting that make it 
visible only to the members of the r-pkg-team ?
You can change the visibility in 
https://salsa.debian.org/r-pkg-team/r-cran-jsonld/edit
under "Permissions".

Paolo

Thanks a lot for stepping in here.

I re-checked the link and I guess it was just a temporary error.

This works for me now.

While your hint was sufficient for me to get the compressed JS out of
the JS sources you might like to have a look at

   
https://salsa.debian.org/r-pkg-team/r-cran-jsonld/tree/a5535fdc49edb0584c774f224c1bc23ff76810f0/debian/JS

There is the error

   
https://salsa.debian.org/r-pkg-team/r-cran-jsonld/blob/a5535fdc49edb0584c774f224c1bc23ff76810f0/debian/JS/get-jsonld.min.err

if I try to build via

   webpack --config ../webpack.config.js lib/jsonld.js dist/jsonld.js 
--output-library=jsonld

No idea whether there is some hidden bug in the JS code.

Kind regards

Andreas.

Hi, I'm an upstream developer for jsonld.js and the one to blame for
the webpack config. ;-)  I'm getting 404 on that salsa repo so I'm not
sure what your script is doing.  In npm world you can build
jsonld.min.js with "npm install && npm run build-webpack".  That's how
it's published to npm.  I've never tried building with apt installed
modules.  If upstream changes would help make this all easier, let me
know.

last link seems a mistake in copy-paste, this is the correct link.

You'll need to update webpack.config.js with system path for it to find 
apt installed modules.


jsonld.js does not work.  The file size of this uncompressed file is 
way
smaller than the minimazion result and doese not work together with 
the

R code.  Thus I really need to undergo the process to create the
minimized JS.

Any idea how to approach this?
