How to npm publish to Nexus group repository?

Question

I installed Nexus Repository Manager OSS 3.2.1 and ran it on local machine.

Configuration

I have three NPM repositories defined in Nexus:

• [PUBLIC] - a proxy for public npm registry
• [PRIVATE] - a private repository for my own packages
• [NPM] - a group repository, allowing access to [PRIVATE] and [PUBLIC] in this order

In Settings/Security/Realms I've added npm Bearer Token Realm.

Downloading

I can download packages from [PUBLIC], which works as intended.

.npmrc 
registry=http://localhost:8081/repository/PUBLIC
npm install react // works fine, downloads from [PUBLIC]

I can download packages from [NPM], which works as intended.

.npmrc 
registry=http://localhost:8081/repository/NPM
npm install react // works fine, downloads from [PUBLIC]

It won't work with [PRIVATE], because I don't have package named react.

Publishing

I don't want to publish to [PUBLIC].

I can publish packages to [PRIVATE], which works as intended.

.npmrc 
registry=http://localhost:8081/repository/PRIVATE
npm publish // works fine, publishes to [PRIVATE]

I can't publish packages to [NPM] and this is weird.

.npmrc 
registry=http://localhost:8081/repository/NPM
npm publish // fails, should publish to [PRIVATE]
// gets HTTP 400

Error

Problem

I understand that I can set up different url for publishing packages with publishConfig in package.json file, but for me it's duplicating configuration.

Can this be done with Nexus group repository?

Answer 1

You can't publish to a group repository. Change the URL you are using to the URL of a hosted npm repository, that will work.
