Rewrite Dynamic form group builder for Angular13+

#angular #form #validations #transform

Today I finished rewriting the library

The new version has better array support with primitive and class based objects

The ValidateIf validator now works, but due to the specifics of how Angular forms work, for correct operation, you need to mark the fields on which this validation depends

All class-validators are converted to Angular asynchronous validators, this made it possible to write custom asynchronous validators

Now it is possible to use several different classes in arrays based on the solution with discriminator from class-transformer

The new version has a hard binding to the class-transformer, since the metadata assigned by the class-transformer is used to determine the types of controls

To implement new features, the original class-transformer had to be abandoned, since it does not publish the meta date that it collects.
Fork that publishes metadata to the global - https://github.com/petrzjunior/class-transformer (PR: https://github.com/typestack/class-transformer/pull/929)

As before, a fork is used to support error translations - https://github.com/EndyKaufman/class-validator-multi-lang (PR: https://github.com/typestack/class-validator/pull/743)

For correct parse metadata, need remove compilerOptions.downlevelIteration and append compilerOptions.emitDecoratorMetadata: true in tsconfig.json

In the current version, native Angular validators for controls are not supported, in the next versions, I will try to implement them, the implementation logic will be different from the original one provided by Angular

For more frequent updates of dependencies and adding new features, integration tests were implemented, part of the functionality is covered, the rest of the code will be covered when I have time
