7 Steps from (Angular) WebApplication to Windows Store

I have deployed fairly easy the .NET Core Alphabet applcation to Windows Store . Supposing that you already have registered the name of the application to the windows store (https://partner.microsoft.com/en-us/dashboard/windows/overview )

Those are the steps:

1. Compile the Angular Application ( with ng build –prod –build-optimizer  )

2. Create a new WinJS App for Universal Windows

3. Copy the results ( index.html and js )from the point 1 to a dist folder

4. Save the files with BOM ( either from VS, Save as, then save with encoding, either using dos2unix –m  <namefile>

5. Modify the main.js by adding : window.location.href=’dist/index.html’;    

6. Modify the Visual Assets to the images of your application

7. Right click the application, Store => Create App Package . And deploy to the store

As a Proof of concept, see https://www.microsoft.com/en-us/p/netcorealphabet/9pdx9rv0xhds#activetab=pivot:overviewtab 

Also, all the source code it is at https://github.com/ignatandrei/netCoreAlphabet ( and you may want to contribute, right?)

.NET Core Alphabet

What I wanted is a simple application ( Web, Mobile, Desktop) that can list , alphabetically, the .NET Core keywords. What is the purpose?

  1. For interviews – suppose you want to test the people knowledge in C#. You start the application( again: Desktop or Web or Mobile) and let the candidate choose a letter. Then you see the keywords for this letter and ask the candidate to explain some of the keywords
  2. For remembering features: there are so many features in .NET language (  https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-version-history ) that for a programmer it is good to know – or to revisit – the features that are in the language.
  3. For contest within programmers  – like the interviews, but for the passionate programmers that want to have an easy way to decide the one with the best memory
  4. Maybe other uses that I do not know  ? Please share in comments

Now with the realization: What I want is the simple application, that has inside the database with keywords and links and any others. From this database, the code sources for the data will be generated and the application(s) will be generated. Also, data should be publicly available to profit from the crowd power –anyone that want to add something can add.

stankins.console execute -o ReceiveRestFromFile -a primaryData/netCoreAlphabet.json -o SenderToTypeScript -a “” -o TransformerConcatenateOutputString -a a.ts -o SenderOutputToFolder -a $(Build.ArtifactStagingDirectory)/data/ -a false

stankins.console execute -o ReceiveRestFromFile -a primaryData/netCoreAlphabet.json -o SenderToRazorFromFile -a primaryData/markdown.txt -o TransformerConcatenateOutputString -a cards.md -o SenderOutputToFolder -a $(Build.ArtifactStagingDirectory)/data/ -a false
 

And to complete all those, it will be put in an AzureDevops pipeline https://github.com/ignatandrei/netCoreAlphabet/blob/master/azure-pipelines.yml 

You can see the result on Android : https://play.google.com/store/apps/details?id=com.github.ignatandrei.netcorealphabet&hl=en  , WebSite: https://ignatandrei.github.io/netCoreAlphabet

Also, if you want , please contribute by making a PR by editing https://github.com/ignatandrei/netCoreAlphabet/blob/master/primaryData/netCoreAlphabet.json or by contributing to enchance the application by solving https://github.com/ignatandrei/netCoreAlphabet/issues

Literary awards–part 5 – interactive

I was wandering how to make more attractive the application – and also gain some interactivity. I was thinking of the possibility  to can say what authors / books did you have read – and make some charts from it.

And here was the principal problem: how, between 2 versions of the data, to remember the authors read ? How to make the authros the same between the various awards ?

Turns out it is not so complicated – the only thing is to not version the “read” database .

So I turn out with just a database per table : one for Nobel, one for Booker, one for Bill Gates books, one for my books, one for reading list and one for all authors. Not a good thing, but this happens when you want to keep the database into the browser and updatable…

Literary awards–part 4 – publish

Part 5: http://msprogrammer.serviciipeweb.ro/2018/11/05/literary-awardspart-5/

 

The publishing part is the tricky one. I wanted Web and Mobile ( could someone help me with the Windows/Linux part  ? )

Github let’s you have the gh-pages  as an website – see https://help.github.com/articles/configuring-a-publishing-source-for-github-pages/ .

What this means in practice ? Menas that , if you deploy the Angular AOT to the gh-pages ( https://github.com/ignatandrei/LiteraryAwards/tree/gh-pages ) , then it should be visible to this url : https://ignatandrei.github.io/LiteraryAwards/

There is also a plugin, angular-cli-ghpages , that does this for you: takes the dist folder ( resulting from AOT Angular build ) and put in gh-pages. You can see the result at https://ignatandrei.github.io/LiteraryAwards/

For Mobile Android I just install the Cordova, copy the dist folder into Cordova and modify the start page in order to point to the Angular results.

But how can I compile Cordova into an Android application ? Turns out that there is a site – https://www.bitrise.io/ – that takes your code ( not only from GitHub, but for free app it is free  ) and compiles it – and it gives you back the apk. Also , it can sign the application – something that Google Play requires. ( For this, I have had some problems with generating keys:

“C:\Program Files\Java\jdk1.8.0_171\bin\keytool.exe” -genkeypair -alias upload -keyalg RSA -keysize 2048 -validity 9125 -keystore keystore.jks
“C:\Program Files\Java\jdk1.8.0_171\bin\keytool.exe” -export -rfc -alias upload -file upload_certificate.pem -keystore keystore.jks

)

Literary Awards–part 3–data

Part 5: http://msprogrammer.serviciipeweb.ro/2018/11/05/literary-awardspart-5/

 

The data – this was the difficult part. As I said, I wanted the data to be local – but how can I put the first time ? And where ? I cannot be cookie, since the authors are a large database for cookies…

There are 3 options : LocalStorage, WebSql and IndexedDB . You can read about those at https://nolanlawson.com/2015/09/29/indexeddb-websql-localstorage-what-blocks-the-dom/ . I choose LocalStorage because it was simpler – however, this is making the startup of the application slower!

Now, how can I store the data ?  For me, a database with select it was fine – but can I find one that works in the browser ? And with javascript ? Apparently, yes! There is a port from C to js of SQLite – https://github.com/kripken/sql.js/ . That means , I can have a SQLIte database and access via Select. Add I can persist too – see https://github.com/kripken/sql.js/wiki/Persisting-a-Modified-Database .

 

With all those, now I am ready to have the Nobel authoirs in my application – but how can I introduce to my application ? The list exists on Wikipedia( https://en.wikipedia.org/wiki/List_of_Nobel_laureates_in_Literature)  and at Nobel site (https://www.nobelprize.org/prizes/literature/) . How can I load those into my SQLite LocalStorage database ?

Here comes another pet project of mine, stankins  . With this I can transform the wikipedia page into this:


db.run("INSERT INTO tableAuthors (Year,Laureate,Languages,Citation,Genres,PictureUrl,LaureateFullWiki,name) VALUES (?,?,?,?,?,?,?,?)", [

"1901",

"Sully Prudhomme",

"French",

'"in special recognition of his poetic composition, which gives evidence of lofty idealism, artistic perfection and a rare combination of the qualities of both heart and intellect"&#91;12&#93;',

"poetry, essay",

"//upload.wikimedia.org/wikipedia/commons/thumb/3/39/Sully-Prudhomme.jpg/75px-Sully-Prudhomme.jpg",

"https://en.wikipedia.org/wiki/Sully_Prudhomme",

"Sully_Prudhomme"

]);

db.run("INSERT INTO tableAuthors (Year,Laureate,Languages,Citation,Genres,PictureUrl,LaureateFullWiki,name) VALUES (?,?,?,?,?,?,?,?)", [

"1902",

"Theodor Mommsen",

"German",

'"the greatest living master of the art of historical writing, with special reference to his monumental work, A History of Rome"&#91;13&#93;',

"history, law",

"//upload.wikimedia.org/wikipedia/commons/thumb/e/e9/T-mommsen-2.jpg/75px-T-mommsen-2.jpg",

"https://en.wikipedia.org/wiki/Theodor_Mommsen",

"Theodor_Mommsen"

]);

Obvious, it is not perfect – but it works!

What can I do with upgrades * because , obvious, each year I should add the Nobel authors ? Nothing simpler: I will modify the name of the database with the application version from package.json

 

In environement.ts ( and in prod)


VERSION: require('../../package.json').version

In the typescript class:


public version: string = environment.VERSION;

Finally , in the create database


this.dbPers = new SQL.PersistentDatabase(

"nobel_v"+this.version,

async function(sender) {

// Initial creation of database if not found

self.createDatabase(sender).then(()=>{

sender.save();

});

},

function(e) {

// Initialization of existing database failed

alert("database failed" + e);

}

);

Literary Awards–part 2–design

Part 5: http://msprogrammer.serviciipeweb.ro/2018/11/05/literary-awardspart-5/

 

One of the first problem that I was design. How to make a design that works on mobile and web and desktop ? Nowadays, the standard seems to be a menu on the left , that will be hidden when the mobile is rendering  . Also , this menu has three lines that allows to expand / collapse.

There are several resources at https://angular.io/resources .

I have tested all the resources with Window Resizer from Chrome and I was impressed by I was impressed by http://akveo.com/ngx-admin .

I have found the  empty starter kit (https://github.com/akveo/ngx-admin/tree/starter-kit ) and I started to modify

 

There was a learning curve here:

The search –  I did not know how to make the search  that was provided , until I found something that was called “

NbSearchService” – always search for a service …

It was a while until a figured how to add a new page to the existing pages ( and now I copy /paste)

I ended up with a bunch of images (https://github.com/akveo/ngx-admin/tree/starter-kit/src/assets/images )and other resources that were not needed

 

All in all, I think that it is more convenient to choose something simpler and not choose a big framework.

The design was pretty simple: Add links on the right to Nobel prize, Booker prize, others and list the authors / books.

And a search will be convenient to find fast the authors on the main page.

But about the data , next time

Part 5: http://msprogrammer.serviciipeweb.ro/2018/11/05/literary-awardspart-5/

 

I was curious to make a project for web and mobile.

The constraints:

1. database just on local, not on a central repository.

2. All with Javascript( OK, TypeScript).,

3. To work on web , mobile, desktop without changing something

 

The purpose of the project was to list the Literary awards – Nobel, Booker, others. ( I maintain myself a list of best books at http://serviciipeweb.ro/propriu/best-of/ )

You can see the final result at ( It is missing the desktop application – but – can you help me with that  – Electron ):
