Very good.So what library do you use for making JSON API? tiPOF or fpweb? Regards, Ara -- http://www.fastmail.com - The professional email service -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

I read business objects with tiOPF using the tiSQLdb visitors, and stream using fpweb. I have almost finishing writing a unit - which I will commit to FPC very soon - that takes a *sample* json file and creates an object from it. The object does not depend on anything, and contains code to stream it from/to json in the format that was used to create it. It should make consuming/producing REST services (using JSON, obviously) very easy. I will integrate it in the jsonviewer application distributed with Lazarus.

Beside you should used to it until now that I always have a question from you ;) But I try to specific whom the next time. Just quote part of the original mail, that is usually sufficient to determine context. To answer your question: - I use Firebird as a database, which I access using SQLDB. A - Data is exposed to webpages using a simple REST layer. There are even Lazarus GUI programs that act as a client to the REST layer. - There is also an RPC mechanism. For this I use ExtJS' ExtDirect protocol, which is a specific version of json-rpc. (this is available in FPC) - Client (browser) is programmed independently in ExtJS and AngularJS by a team of webdesigners. (but you could use fpweb and templates for this as well) It's all very simple, really. In architecture, it resembles the google-apis recently committed in fpc. Also, for example tiOPF provides a lot of the building blocks you may need. Transforming tiOPF objects to JSON for example is really easy and can be done using the rttiutils unit. I even ported that unit to Delphi using the superobject library (by henri gourvest). I've used the same techniques in many different projects now for several years, and I consider it a succesful recipe.

What would be the first step in rewriting it as a web app? - Completely split all GUI logic from business logic. - Create an API that encapsulates the business logic. - In essence you'll then have to rewrite all GUI handling. So, depending on the application: Decide whether you want to write a RIA or a simple series of webpages ?
