## Development zen

This starter includes a watch task which makes development faster and more interactive. It's particularly helpful for [TDD](https://en.wikipedia.org/wiki/Test-driven_development)/[BDD](https://en.wikipedia.org/wiki/Behavior-driven_development) workflows.

To start working, [install Yarn](https://yarnpkg.com/en/docs/getting-started) and run:

```
yarn watch
```

## View test coverage

To generate and view test coverage, run:
```bash
yarn cov
```

This will create an HTML report of test coverage – source-mapped back to Typescript – and open it in your default browser.

## Generate your API docs

The src folder is analyzed and documentation is automatically generated using [typedoc](https://github.com/TypeStrong/typedoc).

```bash
yarn docs
```
This command generates API documentation for your library in HTML format.

Since types are tracked by Typescript, there's no need to indicate types in JSDoc format. For more information, see the [typedoc documentation](http://typedoc.org/guides/doccomments/).

</p>

For more advanced documentation generation, you can provide your own [typedoc theme](http://typedoc.org/guides/themes/), or [build your own documentation](https://blog.cloudflare.com/generating-documentation-for-typescript-projects/) using the JSON typedoc export:

```bash
yarn docs:json
```

## Generate/update changelog & release

This project is tooled for [Conventional Changelog](https://github.com/conventional-changelog/conventional-changelog) to make managing releases easier. See the [standard-version](https://github.com/conventional-changelog/standard-version) documentation for more information on the workflow, or [`CHANGELOG.md`](CHANGELOG.md) for an example.

```bash
# bump package.json version, update CHANGELOG.md, git tag the release
yarn release
# Release without bumping package.json version
yarn release -- --first-release
# PGP sign the release
yarn release -- --sign
```

## All package scripts

You can run the `info` script for information on each available package script.

```
yarn run info

  html-coverage:
    Output HTML test coverage report
  send-coverage:
    Output lcov test coverage report and send it to codecov
  docs:
