This template includes the following features:



- [ESLint](https://eslint.org/) for both TypeScript and HTML templates.

- [Husky](https://typicode.github.io/husky/).

- [lint-staged](https://www.npmjs.com/package/lint-staged) that will run ESLint, Prettier and a custom script to automatically re-generate the table of contents on every commit.

- [Prettier](https://prettier.io/).

- CI/CD with [CircleCI](https://circleci.com/). The pipeline has been set up to lint the source code, run all tests, build, then deploy the final package to NPM registry.

## 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.
