CodeGenerator

Whenever possible, we prefer hand-made code, succinct API and run-time intelligence instead of code generation, but once you hit the limits of what is possible with the language there is no reason not to save some time letting a machine write the remaining redundant code for you.

These classes are designed to be run in the Load application, so the solution should be correctly compiling in order to take advantage of it (unlike the previous Visual Studio Item Templates). On the other side they don't require an installer and are more powerful and customizable.

The aim stills the same though, once the code is generated you should own it and modifying it to your needs.

CodeGenerator class is the facade for 4 classes that do the actual code generation:

• EntityCodeGenerator: Useful if you have a legacy database. Reads the database System Views and generates compatible entities and operation declarations.
• LogicCodeGenerator: Generates Logic classes from compiled Entity classes, including entity tables, registering queries and expression, and implementing operations.
• WebCodeGenerator: [Deprecated] Generates Web views from the compiled Entity classes, including the views itself, an empty TypeScript file and the Client class.
• ReactCodeGenerator: Generates React components from the compiled C# Entity classes, including the Typescript Client class and C# Controller.
• WindowsCodeGenerator: Generates windows views from the compiled Entity classes, including the views itself with the empty code-behind file and the Client class.
• ReactCodeConverter: Best-effort attempt to transform the content of the Clipboard from .cshtml to .tsx, requires manual adjustments but saves a lot of time migrating from Signum.Web to Signum.React.

The classes are all self contained and easy to understand and override to adapt to custom needs.
