Allow Web UI public snaphot build

See https://answers.nuxeo.com/general/q/18dc61af6baa47dd8f6a74ed1fdbf392/compiling-https-github-com-nuxeo-nuxeo-web-ui-fails

Today you cannot build Web UI without access to https://mavenin.nuxeo.com/nexus/#browse/search/npm=group%3Dnuxeo

We'll eventually publish to npmjs central public repo when releasing but not the snapshot.

I understand that https://packages.nuxeo.com would be publically available for this kind of purpose

In https://mavenin.nuxeo.com/nexus/#browse/search/npm=group%3Dnuxeo, we publish:

• nuxeo-elements
• nuxeo-ui-elements
• nuxeo-dataviz-elements
  which are direct dependencies of Web UI and build by our CI. For now, it is https://qa.nuxeo.org/jenkins/job/master/job/nuxeo-elements-master/configure that push packages to mavenin.

Could we even do the same with https://packages.nuxeo.com? No
Small attempt told:

https://qa.nuxeo.org/jenkins/job/master/job/nuxeo-elements-master/302/console.
Anyway, let's say it our JenkinsX future pipeline that would be in charge -> need to update https://github.com/nuxeo/nuxeo-elements/blob/master/Jenkinsfile#L133:

sh "npx lerna exec --ignore @nuxeo/nuxeo-elements-storybook -- npm publish --registry=http://nexus/repository/npmjs-nuxeo/ --tag SNAPSHOT"

in order to publish to https://packages.nuxeo.com/.

We also have forked libraries under the nuxeo scope:

• papertypeahead
• chart-elements
• page

We could manually publish them

 git clone --single-branch --branch 0.6-p3 git@github.com:nuxeo/paper-typeahead.git
 git clone --single-branch --branch webui-p3 git@github.com:nuxeo/page.js.git
 git clone --single-branch --branch 4.0.0-p3 git@github.com:nuxeo/chart-elements.git

then

npm login --registry=https://packages.nuxeo.com/repository/npmjs-nuxeo/
npm adduser --registry=https://packages.nuxeo.com/repository/npmjs-nuxeo/ --scope=@nuxeo

finally

 npm publish --registry=https://packages.nuxeo.com/repository/npmjs-nuxeo/

Npm Repo settings

So far, I am able to login to https://packages.nuxeo.com/ with a GH Personal access tokens with read:org permission. I am admin right there, couple of observation:

• Realms was missing npm Bearer token Realm which is needed to be able to issue

  npm login .. 

  command

• The npmjs-nuxeo repo has Allow redeploy policy which is good and needed to republish snapshot
• The roles:nuxeodev has

  nx-repository-view-*-*-* 

  which should include

  nx-repository-view-npm-npmjs-nuxeo-*-* 

  OK
