There are a lot of files published to npm with this package that are not needed to be downloaded and included in downstream applications.

The `"files"` attribute should be added to the `package.json`, or `.npmignore` should be updated.

### package.json
```
{
  "files": [
    "lib"
  ],
}
```

### .npmignore
```
src/
tests/
.babelrc
.eslintrc.js
.travis.yml
CHANGELOG.md
CONTRIBUTING.md
```
