Scope

If a scope is associated with a registry:

• any install for a package with that scope will request packages from the scoped registry
• any publish for a package name that contains the scope will be published to the scoped registry.

npm config set @myco:registry http://reg.example.com

Set globally

npm set registry http://localhost:4873

Set for a project

Javascript Package - Package.json has a publishConfig property with:

• tag
• registry
• access

Example:

{
    .....
    "publishConfig": {
        "registry": "https://your-host:8081/repository/npm-private/"
    }
    ....
}

Set at the command line

• For one package

// locally for the project
npm install lodash --registry http://localhost:4873
// globally
npm --registry https://your-host:8081/repository/npm-group/ install -g packageName

Publish

To publish

• Filter the file to publish by adding the files to ignore in .npmignore or .gitignore
• Be sure to not have the private property

{
   ....
   "private": true, // Prevent every publication
   ....
}

• Generate a hash from the credential

echo -n 'admin:admin123' | openssl base64

YWRtaW46YWRtaW4xMjM=  # verify that you get the same value (this command can run also on windows and will not give the same result)

• Add a .npmrc file to the project root that will get the credential (A .npmrc is a configuration file that should not be under version control. ie add it in your .gitignore file)

[email protected]
always-auth=true
_auth=YWRtaW46YWRtaW4xMjM=

• Test your package with an install command before publication

cd project
yarn install # to test 
# or
yarn install /path/to/project

• Then publish with npm Yarn publish has another mechanism

npm publish
