Ionic serve getting old errors that were aready deleted


#1

When I run ionic serve, ionic cordova run browser or anything else, I always get an old image at first. I get errors I already corrected or deleted. I dont know where they come from. Ive read ionic serve should fix it and rebuild everything, but its not. When I run ionic serve with livereload, i still get the errors. Then i resave my project and ionic rebuilds without errors!? Im not able to deploy to a device.

ionic cordova run build           
> cordova platform add build --save

Hello,

maybe it helps to delete content of www and .sourcemaps folder.

Best regards, anna-liebt


#3

Hey thanks. Same thing when I delete www directory. Im not seeing a .sourcemaps folder tho


#4

Service worker active?


#5

Hey Fluqz, i’m running into this exact problem too, did you happened to find a solution?


#6

What do you mean by that? I do have some own provider/services running?


#7

No not yet, what about you?


#8

U have a service worker active? Enabled in index.html

Check progressive web app and service worker

They cache stuff which is hard to find


#9

There is a serviceworker in my index file, but it is commented out and I found a service-worker.js
But i dont really know what to do

'use strict';
importScripts('./build/sw-toolbox.js');

self.toolbox.options.cache = {
  name: 'ionic-cache'
};

// pre-cache our key assets
self.toolbox.precache(
  [
    './build/main.js',
    './build/vendor.js',
    './build/main.css',
    './build/polyfills.js',
    'index.html',
    'manifest.json'
  ]
);

// dynamically cache any other local assets
self.toolbox.router.any('/*', self.toolbox.fastest);

// for any other requests go to the network, cache,
// and then only use that cached resource if your user goes offline
self.toolbox.router.default = self.toolbox.networkFirst;

#10

Go to devtools
Tab application
Unregister all service workers

Uncommenting out in index wil not bring u anything if there is a sw already registered under the url

If there is no service worker active and the problem persist you know it is not a sw causing an issue

So the ypu need to look at the code and publish to the community if you need help
