Why is emit undefined in unregister

[Dimitri Kopriwa]

Hi @yyx990803 and thanks for sharing. I am reading at your code and I try to understand why this is not defined in the function scope :

register-service-worker/src/index.js

Line 127 in 756fe7f

 }).catch(error => handleError(emit, error)) 

Thanks in advance,

@yyx990803 please also add SW cache removal to unregister function

// Delete SW Cache
if ('caches' in window) {
    caches.keys()
      .then(function(keyList) {
          return Promise.all(keyList.map(function(key) {
              return caches.delete(key);
          }));
      })
}
