Newbie in Web Programming, where to start?
« on: April 22, 2025, 04:02:38 am »
Hi guys,

I am a newbie in Web Programming and my skill in Lazarus is also mediocore :(,
want to make a website that connect to firebird database server with functionalty create, update,insert, and delete data.

Where can I start? Maybe there are an example that I can learn?

Thanks in advance.

Database access is the same everywhere, focus your learning on the web part first. Here's a probably still adequate starting point. It needs rewriting, I'd like to drop the old routing design and only use the new one, but here's the hello, world (also in the tutorial):
Code: Pascal  [Select][+][-]
  1. uses
  2.   fphttpapp,
  3.   httpdefs,
  4.   httproute;
  5.  
  6. procedure DoHello(ARequest:TRequest; AResponse : TResponse);
  7. begin
  8.   AResponse.Content:='<html><body><h1>Hello,World!</h1></body></html>'
  9. end;
  10.  
  11. begin
  12.   HTTPRouter.RegisterRoute('*', @DoHello);
  13.   Application.Port := 9000;
  14.   Application.Initialize;
  15.   Application.Run;
  16. end.
  17.  
Compile, run, access through http://localhost:9000/ in a web browser of your choice.

I made simple demo example how to use Lazarus in web. Stack - Lazarus as a backend IDE without any other depenndency: only firebird/sqlite3 connection units (IBConnection and sqlite3conn) and fpWeb. Frontend: jQuery and JS plugin dataTable https://github.com/Al-Muhandis/dataTable-demo

I hope this works, I did not check.
At least I save this demo long ago.

Hello.  :)

Maybe this helps. I've created a series of content about creating web applications with Lazarus and WebLaz.

Here's my playlist. Maybe it'll help you get started.  :D

I hope this helps. Greetings from Argentina.

This demo isn't about web programming, but thanks anyway.

So... You must specifiy database name and other DB database parameters in demo.ini. Look readme.md

This database demo is not easy to get working. I never managed it.

It was easier to work with my own database.
The guys here were that helpfully when I started and that patiently.

Do you have IBX installed?
The guys, who wrote it are around. The support is better than every commercial offers.
I was Embarcadero custumer and so glad to have changed. The support cannot compare.
And it is free instead of costing thousands of dollars.

In other words, if you want to work with database install IBX.
And if you want to work with Firebird: Flamerobin.
All free and great.

I wrote a library to make web rad applications and I wrote it for internal use and it works very well. Maybe in the next few years I will give it away for free, but without the sources. Because it took me a lot of time and money.

So how will you install or event compile this thing for multiple platforms without source?

I understand what you mean, the problem is that I had no money and I had to make it and now it works. If I didn't make it I would have had to throw away all my work, for me it was fundamental. So maybe I give it away for free but without sources because doing this thing has impoverished me a bit (it took me time to do it). Making it available already takes time. Now it works on Linux then I'll see. Another problem I have is that I wrote it with Lazaus and I showed the result to someone from Delphi and he told me that they would advertise it, and so if I make it available it would also have to work with Delphi and it takes more time. And I also have to work. It's like a gift that I would give. But I won't give away the sources (I've impoverished myself a bit to do it), it will be precompiled, I have no idea now. And it's not certain that I will even give it away.
