Code Shipping - Registry in Javascript

A registry is:



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

A Content delivery network delivers Static resources such as image locally worldwide



Set globally

npm set registry http://localhost:4873

Set for a project

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


    "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



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]
  • Test your package with an install command before publication
cd project
yarn install # to test 
# or
yarn install /path/to/project
npm publish
