How to upload npm tgz to nexus3 - nexus

Question

I need to setup a private nexus oss 3 for internal nodejs development for our company. The project dependencies have to be download from developer's computer and copy across to the private network, and then upload/publish to the private nexus instance.
We've write some scripts to pull all dependencies in .tgz format form the npm repo, and copied into the private network.
But how can I upload those .tgz files to the npm repo of my private nexus without using the GUI?

Answer 1

You can upload using the UI; but you choose not to use this way.
You can upload using the API; see the docs
You can upload using npm publish; eg.npm --registry=http://nxrm.local/repository/npm-hosted publish package.tgz

For someone who interest for a fast solution, here's my procedure and scripts:
create a hosted npm repo in nexus
create an account for package upload
grant 'npm Bearer Token Realm' realm to the account
run the download script for download packages from public npm repository
run the upload script for upload packages to private npm repository
script for downloading npm packages from public repository
#!/bin/bash
NODE_MODULES_PATH=./node_modules
PACKAGES_PATH=./packages
mkdir -p $PACKAGES_PATH
for url in $(grep _resolved $NODE_MODULES_PATH/**/package.json | awk -F '"' '{print $4}' | sort -u); do
if wget -c -q "$url" -P $PACKAGES_PATH; then
echo "url=$url"
else
(>&2 echo "error download url=$url")
fi
done
script for uploading npm packages to private nexus npm repository
#!/bin/bash
REPOSITORY=[REPOSITORY_URL]
PACKAGES_PATH=./packages
npm login --registry=$REPOSITORY
for package in $PACKAGES_PATH/*.tgz; do
npm publish --registry=$REPOSITORY $package
done
Note:
the packages have to be downloaded locally in the normal way
the script should be running in the project root directory
the [REPOSITORY] can be obtained in your private hosted npm repository

You can also use the rest API to manage components directly:
POST ​/v1​/components
For instance, to upload the package my-npm-package-0.0.0.tgz to the repository npm-private use the following:
curl -u user:password -X POST "http://localhost:8081/service/rest/v1/components?repository=npm-private" -H "accept: application/json" -H "Content-Type: multipart/form-data" -F "npm.asset=#my-npm-package-0.0.0.tgz;type=application/x-compressed"
The complete live API specs can be found at endpoint /#admin/system/api
