The public npm registry is a database of JavaScript packages, each comprised of software and metadata. Open source developers and developers at companies use the npm registry to contribute packages to the entire community or members of their organizations, and download packages to use in their own projects.

With npm private packages, you can use the npm registry to host code that is only visible to you and chosen collaborators, allowing you to manage and use private code alongside public code in your projects. Private packages always have a scope, and scoped packages are private by default.

npm is two things: first and foremost, it is an online repository for the publishing of open-source Node. A plethora of Node. js libraries and applications are published on npm, and many more are added every day. These applications can be searched for on https://www.npmjs.com/.

Installing private npm modules

1. Setting up your npm registry.
2. Combining Gemfury with default index.
3. Building and uploading packages.
4. Install packages via command-line.
5. Install packages via package.json.
6. Working with scoped packages.
7. Keep your privates private.
8. Fixing “Error: CERT_UNTRUSTED”

To publish a scoped package with public visibility, use npm publish –access public .

1. On the command line, navigate to the root directory of your package. cd /path/to/package.
2. To publish your scoped public package to the npm registry, run: npm publish –access public.

npm is the world’s largest Software Registry. The registry contains over 800,000 code packages. Open-source developers use npm to share software. Many organizations also use npm to manage private development.

By default, scoped packages are published with private visibility.

1. On the command line, navigate to the root directory of your package. cd /path/to/package.
2. To publish your private package to the npm registry, run: npm publish.

Creating tokens with the CLI

1. To create a new token, on the command line, run: npm token create for a read and publish token.
2. When prompted, enter your password.
3. If you have enabled two-factor authentication, when prompted, enter a one-time password.
4. Copy the token from the token field in the command output.

private. If you set “private”: true in your package. json, then npm will refuse to publish it. This is a way to prevent accidental publication of private repositories.

This means you can publish the package under your own username (or npm organization), so you’re free from naming problems. Run npm init –scope=username instead of npm init.

npmrc is the configuration file that npm allows to be used globally or user level or project level to optimize your npm environment.

With npm private packages, you can use the npm registry to host code that is only visible to you and chosen collaborators, allowing you to manage and use private code alongside public code in your projects. Private packages always have a scope, and scoped packages are private by default.

When making requests of the registry npm adds two headers with information about your environment: Npm-Scope – If your project is scoped, this header will contain its scope. In the future npm hopes to build registry features that use this information to allow you to customize your experience for your organization.

The most popular private NPM registry for front end developers (IMHO) is Bit.dev (it is in fact a combination of three things: A private NPM registry, a documentation site, and a CLI tool for publishing components).

To set the scope registry use: npm config set @my-org:registry http://example.reg-org.com whenever you install any packages from scope @my-org npm will search in the registry setting linked to scope @my-org for the registry url. To modify the npm registry only for the current project. create a file inside the root folder of the project as .npmrc
