Certain build environments like the Open Build Service require applications to be built without network access. This guarantees that sources are not altered during the actual build. The downside for Node applications is inability to run npm install. This proxy does two things
- it reads NPM published tarballs and presents them on a localhost interface
- it runs
npm install
npm install --production
npm install
npm run build
At this point the application is in dist/ and can be used as from a tagged released version
From the directory of an application where you want to run npm install,
NPM_TGZ=list of all NPM tgz tarballs or directory containing them
node ${path_to_this_app}/dist ${NPM_TGZ} ${npm install parameters}
