javascript - Uncaught TypeError: Cannot read property 'prototype' of undefined (inherits_browser.js) -


after porting our app newer version of create-react-app following error started occurring:

enter image description here

seems reffering inherits_browser.js coming npm module can't pinpoint. line error refers in file ctor.prototype = object.create(superctor.prototype, , seems used webpack somehow.

has experienced issue before / can suggest problematic areas can occur in?

edit

digging deeper issue seems coming file (cipherbase.js)

enter image description here

i had exact problem today. guess had outdated package in project's node_modules folder, because removing , reinstalling fixed problem.

rm -rf node_modules dist npm install webpack --config ./webpack_prod.config.js

notice in case webpack installed locally devdependency. doing rm -rf node_modules , npm install reinstalled webpack , dependencies.

for reference, i'm running webpack 2.2.1, node.js 7.7.4 , npm 4.1.2.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

android - Unable to generate FCM token from dynamically instantiated Firebase -

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
