SDN Event – 3 april 2020 (verplaatst)

Het SDN event van vrijdag 3 april komt er aan!

Op die dag gaan we aan de slag met Micro Services, hoe maak je die in Delphi, maar belangrijker nog, hoe deploy je die op IIS/Windows en op Apache/Linux. En ook, hoe zorg je voor automated certificate renewal voor je https met Let’s Encrypt?

Verder hebben we een, denken wij, leuk idee voor een shoot out sessie. Samen met Cary Jensen heb ik in Denemarken een dergelijke sessie gedaan, maar dan bijna een hele dag. Met de deelnemers samen behandelen we elk onderwerp dat jullie aandragen, met code snippets en jullie ideëén maken we er een interactieve sessie van. Waar moet je aan denken? Bijvoorbeeld code snippets met TStringBuilder, TFDMemtable local storage met Lockbox encryption, embedding assembler, fun met RTTI, of…. wat denken jullie?

Dit event is verplaatst in verband met het corona virus. Hopelijk zien we elkaar weer in juni!

CodeRage 2019 RAD Server Key Value sessions

Thank you for attending my CodeRage 2019 sessions on RAD Server.

The Key Value storage created, deployed and used in the sessions is very simple to build, but also very versatile in its use. Hopefully you will find as many, or even more, uses as I have for the Key Value server code in your own projects with RAD Server.

If you want to replay the sessions, please visit the CodeRage 2019 playlist on YouTube here.

Please find the download with Delphi sources and a partial emsserver.ini here:

David Intersimone (DavidI) has created an excellent handbook on RAD Server which can be found here.

Have fun creating your own RAD Server solutions!

Some after session thoughts

In an attempt to shorten the RADServerKeyValue Client video a part of the video at the end was removed that should not have been removed. This involves using a key/value pair with uploading a larger or more complex text. The source code in the rar file you can download has the correct source code.

This Key Value store code has special handling for any key with a value ‘body’. In response to this keyword the RAD Server Key Value package assumes the body of the Request contains a UTF8 encoded text to be placed in the value for the dictionary. This makes it possible to put text in the Key Value storage that would be difficult to put as a URL parameter, either due to size constraints for URL segments, or due to special characters not allowed in URL parameters.

By setting the recycle time of the IIS ISAPI to 24 hours, the in-memory Key Value pairs will remain available for that period. If you want you can add persistency for this dictionary by storing the data in a database in the RAD Server backend.

You may want to add manual support for different MIME types with EndPointProduce and EndpointConsume and use EMSFileResource and EMSDBResource to feed files or database tables back to the client.

 

Coderage 2018 – Building Microservices and Progressive Web Apps (PWA) with Delphi

Thank you for attending my Coderage 2018 session on Building Microservices and Progressive Web Apps (PWA) with Delphi and TMS WebCore.

If you want to replay the session, please visit the Coderage 2018 page on Embarcadero Academy.

Please find the download with source and slides here:

Have fun creating your own REST microservices and PWA‘s!

Note: with newer versons of TMS WebCore you may need to change two lines of code in the file UnitJSONHelper.pas.


Weblib.REST, Weblib.JSON;


lArray := lJSONObject.GetJSONValue('result');

Additionally the no longer needed WebRunner lines in the Project file TheCounterWeb.dpr should be automatically removed when you open the project, if not remove them manually.

CodeRage 2018 – 4-6 December 2018

CodeRage 2018 is just around the corner!

CodeRage2018

CodeRage2018

The complete schedule:
https://www.embarcadero.com/coderage-2018

This CodeRage I’m showing you how to build microservices and how to consume them from desktop, Android mobile and using a HTML / JavaScript web app. The web app uses TMS WebCore and PAS2JS, but goes beyond basic coding as it also shows you how to convert the web app to a Progressive Web App, or PWA for short

The boilerplate code is of course available for download, please use it to jump start your own software.

Oh, and the nice thing about PWA, an Android device will offer the user the option to install the web app as an actual app with an icon on the start screen. Good stuff!

Register here, it’s free but infinite value for money:
