Special attributes

Classes can have attributes that change the way they are transformed, let's go through them.

Using the #[TypeScript] attribute is not only a way to tell typescript-transformer to transform a class, but it can also be used to change the name of the transformed class:

#[TypeScript(name: 'UserWithoutEmail')]
class User
{
    public int $id;
    public string $name;
}

This will transform the User class to UserWithoutEmail in TypeScript.

export type UserWithoutEmail = {
    id: number;
    name: string;
}

Each type will be located somewhere either being a file when using the ModuleWriter or in a single file when using the GlobalNamespaceWriter. The location of the type can be changed by using the #[TypeScript] attribute:

#[TypeScript(location: ['Data', 'Users'])]
class User
{
    public int $id;
    public string $name;
}

This will transform as such:

declare namespace Data.Users {
    export type User = {
        id: number;
        name: string;
    };
}

By default, the location is based on the namespace of the PHP class.

It is possible to completely remove a class from the TypeScript output by using the #[Hidden] attribute:

#[Hidden]
enum Members: string
{
    case John = 'john';
    case Paul = 'paul';
    case George = 'george';
    case Ringo = 'ringo';
}

This is particularly useful when using the EnumTransformer and you want to hide certain enums from the TypeScript.
