How to migrate/update a Ionic1 to Ionic4 app - ionic-framework

noob here.
I did an app on ionic, is pretty basic just images, buttons and text; the buttons are linked to another page and stuf like that, i mean there is no logic still like a loop or something.
What i was asked is to update the project of the app that is on ionic1 to ionic4 because someone that is willing to help me works with ionic4 and not ionic1.
Is there a guide for noobs to do this? i have been looking on google but nothing pop up
i read this but to a noob makes no sense https://ionicframework.com/blog/a-guide-for-migrating-to-ionic-4-0/
But the solution is kind of like this:
"Then, create a new Ionic 4 application and begin porting features over. Once the team is comfortable that the new app is stable, you can shut down the Ionic 1 app"
Thanks in advance!

The reason why there isn't a straightforward guide is because an absolutely huge amount of changes were made.
Take a look at the breaking.md document on the repo, its over 1000 lines long:
https://github.com/ionic-team/ionic/blob/master/angular/BREAKING.md
There is a linting tool that could help you identify the main areas that you need to migrate, and if it's just a simple app like you say then it could do a lot of the work for you:
https://github.com/ionic-team/v4-migration-tslint
Beyond that the only real way is to look at every tag and then search it and see if its listed in the breaking change. If it is then update it.
The reason why the official advice is to make a new app and port features over is that otherwise you will have a non-working app basically forever up to the last moment where it starts working. Not the best way to learn so they say start with a new working app and build bits in it that are already Ionic 4.

Testing Facebook Messenger Scan Code

Facebook recently announced the introduction of messenger codes which can be used to add new contacts and, more importantly, communicate directly with businesses and business pages (which is why I'm interested in it).
It took me ages to find it but on the bottom left of the messages tab on my Facebook page I have the option to download my code in three different sizes - clicking the disc will open a modal window where you can click the Download button and choose from 300, 600 or 1000px PNG file downloads.
NOTE: While they are PNG files the background is not transparent which seems like a bit of an oversight to me but hey ho that's what Photoshop is for I guess.
The problem is that while I can download my code I can't find any way to test it on printed materials (or even electronically at the moment!). The scanning feature doesn't seem to have been rolled out for me yet (I tried re-installing the Messenger app to see if I got a newer version but that didn't work) and nor for anyone I know (I'm in the UK). The codes are bespoke to Messenger so can't be scanned or tested using any other app.
I'm probably too far ahead of the game but is there any way I can test to see if my code scans correctly, or anywhere I can go to find out? I would like to use it on some promotional material which is likely to be long term materials that I don't want to have to update in the near future (several years, by which time it's likely these codes will be more commonplace).
I also need to know what the redundancy is like. For example the high redundancy QR codes I generate can have up to 30% of the code covered while still being usable, which is great for design purposes. I can't find any official documentation as yet for these codes at all, let alone what is required, what the spec. is etc.
I know the most likely option is 'sit and wait' but I really would rather not if possible. I've never been very patient...
Thanks
UPDATE: My Messenger app has now been updated so I can test, but I'm leaving this here in case anyone knows of another way to test perhaps? If someone doesn't have Messenger on their phone for example.

OwnCloud enhance core features with App (eg. user registration)

I started looking into OwnCloud app development to add some capabilities I would like to my server. To me it seems like Apps can't modify anything like the Login page or User Management page. Is this the case?
I want to build a user registration app and would love to integrate it into the user management page (if not and it has to exist as its own app page not a big deal). The one big problem I see so far is not being able to add a "Register" link to the login page. I could just go in and add it to the source manually, but I would like to keep the App self contained so others can use it too.
If this is not possible to do in an App I may just need to modify the core application and then see if they will accept my feature addition in a pull request.
Thanks to anyone who can shed some light on this for me. I don't want to waste my time trying to figure out how to do it with an App on the platform if it wont be doable.
After a lot of digging around I did figure out a way to do this.
In the App's app.php file, you can force a script to be loaded if the plugin is enabled:
$api->addScript('script_name'); // without .js
In that script jQuery can be used to add the elements to the page where you need them.
This was a good solution for me since I only needed to add a single button to the login page. I can see this being a bad idea if you want to make vast modifications. At that point you might as well just create a separate page that you have full control over.

Script that refreshes a website on all devices at the same time while developing

Some weeks ago I red about a script at github that will refresh a websites on all devices in the network at the same time while developing on it but I just can't remember the name.
I hope this answer doesn't count to the "this is not a research center forum" category but more I hope that someone might remember it we can share the answer for users that might looking for it too.
Before I get a thousand downvotes, please tell me if this a question at the wrong place (but where else then?)
Meteor has been getting a lot of attention lately, but if all you need is a full page refresh, you could use any pub/sub framework, like Faye, and a few lines of javascript.
Ok, I finally found it again:

Up to date instructions for September 2011 onwards for beginners

Sorry for this basic question but all attempts at Googling and using facebook help only provide out of date information.
I am attempting to make my first fb app. Just an html page saying hello. From what I understand the app (or webpage) is stored on my server and I set up a facebook app that basically points to the URL of the app (or webpage) on my server.
Is this basically correct.
Where do I enter this URL information in my edit app screen. I have followed the latest fb instructions and all I see when I view the app is the admin page in fb for the app.
Does it take a long time for the page to appear.
Is there a current idiots guide. The app design is not a problem for me loading it in to facebook is the problem.
Unfortunately this wasn't very helpful, not because of what you posted but due to the fact that it appears that Facebook has updated the way in which pages are linked to again.
The pages you suggested I look at were well laid out with lots of information on them but they are already out of date and do not seem to correspond with the layout of the Facebook 'dev app' and even the fields in the form seem to have been either dropped added to renamed.
Thanks for trying to help me and I hope that FB may produce some up to date information soon and not keep changing the interface.
I can completely understand your confusion - the Facebook docs give very little information for the complete beginner. The 'Getting Started' section makes some massive assumptions and completely ignores huge key areas you need to know to get your first application up and running.
So to address your points:
Yes, this is basically correct. Apps on Facebook are served up to the user in one of two ways. Either as a 'Canvas App' or a 'Tab App'. A Tab App is an application you can install as a tab on a profile page. A Canvas App can operate on it's own page and has more room as there's no left menu as you would have on a profile page. You can configure a single app to work in both ways.
To edit your application settings, go to your own Facebook home page. Use the search bar to search for the 'Developer App'. Typing in 'developer' should do it - it should be the first result in the App section with around 830,000 monthly users. This Developer app is the window into your own app settings. You need to install it if you haven't already. It's a hub where all the apps you create will be available for you to edit. Whenever you want to edit one of your app settings in future, you click the Developer bookmark that will now be in the left menu on your own Facebook home page.
No. Apps are basically an iframe onto your code. There should be very little if any wait at all. Start with something very simple like spitting out some straight html so you can easily tell if things are set up correctly.
Yes. I found thinkdiff.net to be massively useful in the early days to get my head round the basics and then more advanced concepts. There's tons of examples ranging from very simple to quite advanced. I've just had a quick look around and found this page which should give you a decent head start in getting things moving. Note: I have no affiliation with thinkdiff.net at all - I just found them helpful in the past.
Finally, a request from me; this whole stack overflow thing is new for Facebook developers and very few people are voting up answers they consider helpful. This means new users to SO but experienced FB developers can't vote up good answers and vote down bad ones as we need enough Reputation Points to do so. If this has helped you, please ensure you vote up the answer. Of course if it was rubbish and you're just as lost, dont :D
Hope I've helped in some small way; I know I was completely lost for the first few weeks with FB development and even now there are things that make me tear my hair out! In the end it's very rewarding, but you have to put in the time. Good luck :)

iPhone SDK: Ideas on how to implement a help facility for application

We we wondering what are some ways developers have added a help function to their apps. What are some techniques people have used?
One way we were thinking of is to us UIWebView to display a HTML file with help instructions.
Thoughts appreciated.
I'm using UIWebView right now which pretty much contains all the help in a single page, along with some JQuery things to display popups, etc. But I like the way iCab Mobile (et al.) are doing things which is a sectioned UITableView with each row a separate topic or section within their overall help information (complete with icons...) then in their bundle they have each section in its own html file, organized by localization.
Another thing in my queue for the next release is to provide a dynamic "News" view. The rough idea is as follows... I have on my server a file or CGI where I can place small bits of news I'd like to push out to users. On startup, my app checks for network availability and if present, start a thread to see if anything has changed on the server since last updating the News data. If changes present, post an alert letting user know, and asking if they'd like to read it now. At that point, the latest news is already downloaded and cached, so they can simply read it later if they want, and I won't post anymore alerts until the server file changes again. (And one could add a preference/setting to disable these alerts.)
I'm thinking this would be a good way to let people know that some nasty bug is known and fixed and an update is sitting in the queue, solicit beta testers, promote upcoming features or other apps, etc. I can see where constant alerts everytime I've got something new to promote would get annoying, so having a setting to disable them means the user never has to read them unless they want to. Although some kind of override to warn of recently discovered/fixed bugs seems sensible.
FWIW, the author of Mover+/Mover has just started doing a similar thing, though I think Emanuele is perhaps only showing one Notelet at a time, whereas I envision a bit more of a history (shown in UIWebView) until I decide to age stuff off the bottom of the stack.
I'm using a scroll/page view to show several images containing small notes. Each image then tells the user about the more advanced functions on a specific part of the app.
In my opinion the help should only contain information that isn't a 100% relevant for the use of the application. It should be things the advanced user should use to make more use of the app. It should contain gold for the power users. The "basics" should be so obvious that no help would ever be needed. If that's not the case, I think, you've failed as a developer on the iPhone platform.
(Here's a screen shot from my demo app)
I'm currently creating a fairly complicated app. I'm thinking of doing help as a semi-transparent overlay - help in text form is hard to swallow for users; it's much more helpful to just point at stuff and say "this does that".
