B4J Library [Web][BANano] Website/App/PWA library with Abstract Designer support






INTRO

BANano is a new B4J library to websites/webapps with (offline) Progressive Web App support. Unlike its big brother ABMaterial, BANano does not rely on any particular framework like Materialize CSS. You will have to write that part yourself, but on the other hand, you have the choice to pick which one.

Why a second framework? Well, from the start ABMaterial was build with a back server in mind. B4J has great support to setup a very powerful jServer to handle web requests. Which does mean all intelligence is at the server side and you have the full power of B4J to do whatever you want (secure database access, serial communication, cache control etc). With B4JS, some of this intelligence could be transferred to the browser side, but the app still needs internet/intranet access so this is as far as it could go.

INTRODUCTION PODCAST TO BANano (A.I. generated from the booklet)

http://sndup.net/hncr6

BANano is a different animal. It can use a Service Worker to 'install' the web app in the browser, so it can also work when the user is offline. While ABMaterial builds the page from the server side, BANano builds it from the browser side. This means EVERYTHING you write in B4J is transpiled to Javascript, HTML and CSS.

But with great power comes great responsibility! Unlike ABMaterial, some basic knowledge of HTML, CSS and to some extend Javascript is needed to build BANano apps. It makes excellent use of B4X's SmartStrings to create the HTML part of the app. BANano gives you a set of tools to write your own wrapper around any framework (MiniCSS, Skeleton, Spectre, Bootstrap, ...), which then can be easily used to quickly build webapps/websites.

OVERVIEW

A quick overview to show the different uses of both frameworks:


So both frameworks have their specific target, both for the programmer and the app you want to make.

No, the request was to short before release. This is not a simple one to implement and will take quite some time.

Note: when the final version of jServer 4 is released, I will release a new version where the used java libraries will be also updated to the ones the new jServer uses. This has no impact on your projects, but I think it is better that the library uses the same versions as jServer.

I suggest you download the library and booklet from post https://www.b4x.com/android/forum/t...h-abstract-designer-support.99740/post-627764 and follow the install instructions in the booklet. New menu items will appear in the IDE after you copied the templates to the B4J Additional Libraries folder. The 'BANano Skeleton' project type is now called 'BANano PWA'.

BANano 8.12 Beta available

Most of the changes are internal within the core transpiler engine (e.g. the dead code detector has been rewritten from scratch).

Support for Anonymous Functions, something that is very common in JavaScript and can often be used instead of callbacks. They are 'Subs' within 'Subs'.

e.g. here we pass an Anonymous Function to another Function (SetTimeOut) as an argument:
B4X:
Dim FuncTimer As BANanoObject
Dim FuncArgs As List

FuncTimer.Sub(FuncArgs)
       ' do something and restart
        BANano.Window.SetTimeout(FuncTimer, 1000)
FuncTimer.EndSub
 
BANano.Window.SetTimeout(FuncTimer, 1000)

Such a function can also be called directly:
B4X:
Dim aa As Int = 5
Dim x As Int
Dim y As Int
 
Dim z As BANanoObject
z.Sub(Array(x,y))
        y = x * a
        Return y
z.EndSub

Log(z.Execute(Array(4,5)))

As such a function is an just object, it can be assigned to a property of another object. When wrapping a lib you often see that a property should be a function, especially in case of events. Previously we would've build a callback but now you can also use such a function.

Show an alert when the user clicks on the webpage
B4X:
Dim onClick As BANanoObject
onClick.Sub(Null)
        BANano.Alert("Hello there!")
onClick.EndSub

' get the document object
Dim document As BANanoObject
document.Initialize("document")

' assign our new method to the onclick event 'property' 
document.SetField("onclick", onClick)

New BANano objects are:

BANanoNotification: browser notifications
B4X:
Dim notif As BANanoNotification
notif.Initialize(Me, "notif") 
notif.Show("Hallo", DateTime.Now, "BANano is here!", "http://127.0.0.1:8090/api/files/d4m3p945iz74uup/u6lg1v53eoq527t/golf_alain_AuXAZ05yuM.jpg?thumb=100x100", "http://127.0.0.1:8090/api/files/d4m3p945iz74uup/u6lg1v53eoq527t/golf_alain_AuXAZ05yuM.jpg?thumb=100x100", 500)

BANanoFormData: a wrapper around the FormData object, often used to upload data to a server. Usage:
B4X:
Dim record As BANanoFormData
record.Initialize

record.Append("id", Id)
record.Append("created", Created)
record.Append("updated", Updated)
record.Append("username", UserName)
record.Append("email", Email)
record.Append("verified", Verified)
record.Append("password", Password)

New lightweight components in BANanoSkeleton (now over 50+):
SKBarcode
SKBigRange
SKCard
SKCaroussel
SKChart
SKCollapsable
SKGanttChart
SKGauge
SKMobileMenu
SKPercentageBar
SKProgressBar
SKTimeInput
SKTimeline
SKTimePicker

BANanoSkeleton now also supports flex columns.

And a special object SKLayout which makes it possible to add components on the fly very fast with code.

Some examples:
B4X:
Dim Layout As SKLayout
layout = Layout.Initialize(Me, "body" ) ' important! set the return value of the .Initialize method back in the layout variable
layout.AddFlexColumns(1,12,6,4, "center" )
layout.LastRow.Column(1).MarginTop = "20px"
layout.LastRow.Column(1).MarginBottom = "20px"

' the .Add object will give you a quick method to create each type of BANanoSkeleton object         
Dim bc As SKBarcode = Layout.LastRow.Column(1).Add.Barcode( "bc" , "bc" , 64, 0, "CODE128" , "/Z000001" , True, 1, 14)
bc.PaddingTop = "10px"

B4X:
Dim Layout As SKLayout
Layout = Layout.Initialize(Me, "body" )
Layout.AddFlexColumns(1,12,6,4, "center" )
layout.LastRow.Column(1).MarginTop = "20px"
layout.LastRow.Column(1).MarginBottom = "20px"
          
Dim chart As SKChart = layout.LastRow.Column(1).Add.Chart( "chart" , "chart" , "My chart" , "pie" , 300)
chart.AddLabels(Array( "2020" , "2021" , "2022" , "2023" ))
chart.AddDataSet( "Sales" , "" , "" , Array(1000,1500,500,3000))
chart.Build

B4X:
Dim Layout As SKLayout
Layout = Layout.Initialize(Me, "body" )
Layout.AddFlexColumns(1,12,6,4, "center" )
layout.LastRow.Column(1).MarginTop = "20px"
layout.LastRow.Column(1).MarginBottom = "20px"
          
Dim bigrange As SKBigRange = Layout.LastRow.Column(1).Add.BigRange( "bigrange" , "bigrange" , "My BigRange" , 20, 0, 100, 10, "%" , "#ffffff" , True)
bigrange.Classes = "banbr-input-bigrange"
bigrange.Width = "100%"
bigrange.Style = $"{"border-radius": "1rem"}"$
          
bigrange.ElementLabel.SetStyle( $"{"background-color": "#334D5C", "color": "#fff"}"$ )
          
bigrange.ElementBottomBarFill1.SetStyle( $"{"margin-left": "0%", "width": "100%", "background-color": "#f1a70f"}"$ )
bigrange.ElementBottomBarFill2.SetStyle( $"{"margin-left": "0%", "width": "0%", "background-color": "#f1a70f"}"$ )
  
Dim tmpTick As BANanoElement
tmpTick = bigrange.GetElementTick(bigrange.GetNumberOfSteps+1)
tmpTick.SetStyle( $"{"color" : "#f1a70f", "font-weight" : "bold", "font-size" : "1.2em"}"$ )

With the final release of BANano 8 will also come an update version of the documentation en some extra BANanoLibraries, but this beta can give you a taste of what is coming.

Note that both libraries are already used in full production within our company for over 6 months so we have ironed out many bugs already and we consider it now stable. But it is always nice if someone else can test them too and report back bugs to us.

Thank you very much for this great update.

Have you been able to fix some bugs in the previous version?

The first two should be, but the last two I will recheck because they don't seem to be solved although I'm pretty sure they were at some point
Let met go through my backups to find out where I lost them...

Thx for reporting this because we never use these kind of constructions in our PWAs it was never noticed. I should add them to my test bank.

I have had to change the folder structure of additional libraries, I had this:


I had to move the B4J subfolder

Next update will support this folder structure too. As we only use B4J within our company, our folder structures didn't look like this yet.

I will try to release a new beta this week as it appeared the fixes for 'Boolean without variable' and parantheses bug were never pushed . I have to rewrite them from scratch.

I have not found any new bugs in the beta version. Is the booklet available to review the new features?

Hi,
I am working myself trough the booklet since I am a newbie on these topics.
Note that the Chrome web server plugin used in the booklet does not work anymore.
