.NET Core And Angular at CodeCamp Bucuresti

I have presented on Saturday at https://bucuresti.codecamp.ro/ a technical talk about how to make a fast POC that can run on Web, Desktop and Mobile , The presentation will show a clear example of code that is necessary for that ( code at https://github.com/ignatandrei/angNetCoreDemo/  ).

You can see working demo without CORS at https://ang-net-core.herokuapp.com/ , with CORS at https://ignatandrei.github.io/AngNetCoreDemo/ and a Mobile app at https://app.bitrise.io/artifact/9332781/p/ef7a0b7e945d69e01697390dcef867de

It was a good opportunity to learn something new at the conference – many good technical tracks and old friends that is an opportunity to see again.

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…

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

)

You can find the Google Play application at https://play.google.com/store/apps/details?id=com.msprogrammer.com
