Using as a library

You can use all of the same CLI options when using license-ls as a module (with the exception of anything that is specific to out format - such as include or format).
When using it as a module, the function will always return a promise that resolves to an Array and will include all properties (['id', 'name', 'version', 'license', 'repository', 'author', 'homepage', 'path', 'dependencyLevel', 'description'])

const licenseLs = require('license-ls')
const options = {
    depth: 1,
    prod: true
}

licenseLs(options)
.then(result => {
    // do your thing
})
