Verdaccio relies on `yarn` instead `npm` to download depenedencies.

*Note: the current build only will build with `➜ yarn` latest.*

```bash
  yarn install
```

## Scripts

We have a list of scripts that you will use for diferent kind of tasks, in the following section
we describe all posible task based on branches.

### Branch (2.x)

On branch `2.x` the unique part we have to build is the UI which is based on React.js, webpack and CSS Modules.

#### Scripts

script | Description
--- | --- |
release | this script is used to generate changelog and raise up the version according the commits messages
prepublish | it ensures before publish the new ui is being generated
test | run all the test
pre:ci | specific task for CI, build the UI required for test
test:ci | run test generating coverage
test:only | run only test
test:coverage | run `nyc` as a wrapper to generate coverage with mocha test
coverage:html | run `nyc` to generate coverage reports
coverage:publish | publish on `codecov` the coverage (don't use it)
lint | run the linting for javascript code.
lint:css | run the linter for `css`
dev:webui | run a `webpack` server with hot reloading enabled `http://localhost:4872/#/` it requires a `verdaccio` server running in port `4873`.
pre:webpack | prepare the field for webpack (it a substask of `build:webui`)
build:webui | create the static assets for the UI with `webpack`
build:docker | create a local docker image with `verdaccio`
build:rpi | create a local docker for raspberry pi image with `verdaccio` **(experimental with no support)**
