Note: all the examples are focused on Nx, if you don't see an explicit command for an Angular workspace just change nx for ng.

Also, when you find references to workspace.json, you can find your file under the name angular.json.

🚀 Quick Start (local development)

1. Add ngx-deploy-npm to your project. It will configure all your publishable libraries present in the project:

   • Nx🐬

     npm install --save-dev ngx-deploy-npm
     nx generate ngx-deploy-npm:install
     

   • Angular🅰️

     ng add ngx-deploy-npm
     

2. Deploy your library to NPM with all default settings.

   nx deploy your-library --dry-run
   

3. When you are happy with the result, remove the --dry-run option

🚀 Continuous Delivery

Independently of the CI/CD that you are using you must create an NPM token. To do so, you have two methods

• Via NPM web page
• Using npm token create

CircleCI

1. Set the env variable

   • On your project setting ser the env variable. Let's call it NPM_TOKEN

2. Indicate how to find the token

   • Before publishing, we must indicate to npm how to find that token, do it by creating a step with run: echo '//registry.npmjs.org/:_authToken=${NPM_TOKEN}' > YOUR_REPO_DIRECTORY/.npmrc
   • Replace YOUR_REPO_DIRECTORY for the path of your project, commonly is /home/circleci/repo

3. (Optional) check that you are logged

   • Creating a step with run: npm whoami
   • The output should be the username of your npm account

4. Deploy your package

   • Create a step with:

   Nx🐬	Angular🅰️
   nx deploy your-library	ng deploy your-library

5. Enjoy your just released package 🎉📦

The job full example is for an Angular project is

# .circleci/config.yml
jobs:
  init-deploy:
    executor: my-executor
    steps:
      - attach_workspace:
          at: /home/circleci/repo/
      # Set NPM token to be able to publish
      - run: echo '//registry.npmjs.org/:_authToken=${NPM_TOKEN}' > /home/circleci/repo/.npmrc
      - run: npm whoami
      - run: npx nx deploy YOUR_PACKAGE

You can check the steps suggested in the CircleCI's guide

📦 Options

--build-target

• optional
• Default: Doesn't have any default value (string)
• Example:
  • nx deploy --build-target=production – The configuration production is being used to build your package

The buildTarget simply points to an existing target configuration on your project, as specified in the configurations section of workspace.json.

This is equivalent to calling the command nx build --configuration=XXX. This command has no effect if the option --no-build option is active.

--no-build

• optional
• Default: false (string)
• Example:
  • nx deploy – Angular project is build in production mode before the deployment
  • nx deploy --no-build – Angular project is NOT build

Skip build process during deployment. This can be used when you are sure that you haven't changed anything and want to deploy with the latest artifact. This command causes the --build-target setting to have no effect.

--package-version

• optional
• Default: Doesn't have any default value (string)
• Example:
  • nx deploy --package-version 2.3.4

It's going to put that version on your package.json and publish the library with that version on NPM.

--tag

• optional
• Default: latest (string)
• Example:
  • nx deploy --tag alpha – Your package will be available for download using that tag, npm install your-package@alpha useful for RC versions, alpha, betas.

Registers the published package with the given tag, such that npm install @ will install this version. By default, npm publish updates and npm install installs the latest tag. See npm-dist-tag for details about tags.

--access

• Default: public (string)
• Example:
  • nx deploy --access public

Tells the registry whether this package should be published as public or restricted. It only applies to scoped packages, which default to restricted. If you don’t have a paid account, you must publish with --access public to publish scoped packages.

--otp

• optional
• Default: Doesn't have any default value (string)
• Example:
  • nx deploy --otp TOKEN

If you have two-factor authentication enabled in auth-and-writes mode then you can provide a code from your authenticator with this.

--dry-run

• optional
• Default: false (boolean)
• Example:
  • nx deploy --dry-run

For testing: Run through without making any changes. Execute with --dry-run, and nothing will happen. It will show a list of the options used on the console.

📁 Configuration File

To avoid all these command-line cmd options, you can write down your configuration in the workspace.json file in the options attribute of your deploy project's executor. Just change the option to lower camel case.

A list of all available options is also available here.

Example:

nx deploy your-library --tag alpha --access public --dry-run

becomes

"deploy": {
  "executor": "ngx-deploy-npm:deploy",
  "options": {
    "tag": "alpha",
    "access": "public",
    "dryRun": "true"
  }
}

Now you can just run nx deploy YOUR-LIBRARY without all the options in the command line! 😄

ℹ️ You can always use the --dry-run option to verify if your configuration is right.

🧐 Essential considerations

README, LICENCE, and CHANGELOG

Those files must be in the root of the library. They are being copied by the builder at the moment of deployment.

If you have those files outside the project's root, you can create a symbolic link to solve that problem.

See symbolic links on git to know how to create them properly.

Version bumping

This deployer doesn't bump or generates a new version of the package, it just builds the package/library, take the package.json as it and publish it. You can use --package-version option to change it.

Only publishable libraries are being configured

For Nx workspace, only publishable libraries are going to be configured

🏁 Next milestones

We are looking forward to the following features:

• Implement Continuous Everything with Github Actions:
• Specify which library configure the builder on the installment (init)
• Ways to copy files into the final build, like README, LICENCE, and CHANGELOG files

Your feature that's not on the list yet?

We look forward to any help. PRs are welcome! 😃
