Use Private NPM Registry

I just want to share some private NodeJS modules for reuse in my other projects. A simple private registry is a good choice. sinopia is what I used.
The installation is very easy.

$ yarn global add sinopia
$ sinopia &
$ npm set registry http://localhost:4873/

After this, we can add a user to the new registry.

$ npm adduser --registry http://localhost:4873/

Now we need to update the module's package.json to remove the "private": true and add following publish config.

"publishConfig":{
  "registry":"http://localhost:4873"
}

Then we can run npm publish to publish the module. The new published module can be installed using npm or yarn in other projects.

Switch to Verdaccio

Verdaccio is a fork of sinopia with better maintenance and documentation.
