Db2Code–part 1–idea

From the second year that I have started programming, I find tedious to replicate the tables structure to code and to generate classes and SQL . I started asking questions  – and no one has ever envisaged near me an ORM ( it was not a definition then ). I have made my own ORM  – and it was paying . However, I did not know how to market  – so oblivion was his fate.

Moving to this year , there are many ORM . One of those is EFCore – that has also a revers engineer /  scaffolding ready : https://learn.microsoft.com/en-us/ef/core/managing-schemas/scaffolding/ . But how generate all classes , controllers and others ? I was into https://learn.microsoft.com/en-us/dotnet/csharp/roslyn-sdk/source-generators-overview – but this does not allow programmers to modify what it generates. But , fortunately, this year EFCore7 has templates, based on t4 templates : https://learn.microsoft.com/en-us/ef/core/managing-schemas/scaffolding/templates?tabs=dotnet-core-cli . That means that now we could generate whatever we need!

So this is the project : A DB2Code Visual Studio Template. You can download from https://marketplace.visualstudio.com/items?itemName=ignatandrei.databasetocode  . Also, the source code is at https://github.com/ignatandrei/queryViewer/ . Download, modify the connectionDetails.txt and it will generate from you everything to WebAPI from SqlServer or Sqlite ( more providers soon). Also, it generates  different projects ( models, context, controllers) – and you can also modify the templates. It works ( for the moment) just with tables with 0 or 1 PK.

The next parts will be only about the challenges to develop such a solution.
