Angular compatibility

How to use

Configurations

• Find-and-replace all instances of angular-library-template with your library's name.
• Rename folder angular-library-template inside projects to the your library name.
• Update all component prefixes from lc to your own choosing.
• Within your CircleCI's Organization Settings, add a new context named npm, and add an environment variable named NPM_TOKEN to that context to publish the built package to npm.
• Add an SSH user key to your CircleCI project so that version commits can be pushed into your remote repository.
• Create a project level environment variable named GH_KEY that contains the fingerprint for the SSH user key created above so that CircleCI can commit back to your repository on Github when the versioning job runs.

Development

To develop your library code, just add changes to lib folder.

Be sure to add anything that you'd like to export to public-api.ts file, or else, nothing can be imported from your library.

Testing

Unit testing

Execute pnpm test to run all of your unit tests in watch mode, or pnpm test:ci to run it in non-watch mode.

Visual testing

To visually check your components/directives, you can import them into projects/visual-test app and use the imported symbols as normal. Changes made to your library code will also cause the visual app to auto-reload after running pnpm start at the root of the product directory which will start a regular Angular app on http://localhost:4200.

Building and publishing

Before you publish your library, you should update your README file (Be sure to not change the ## Table of contents section as this is updated automatically by a script that runs on every commit hook) and choose an appropriate software license. Anything added to README.md file will be copied to the final distribution inside dist/your-library-name folder to be published to the npm registry, additionally, the LICENSE file and package.json file inside projects/your-library-name folder will also be copied to distribution folder, so make sure you configure your package.json accordingly.
