FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Docs
Basic
Maping is done throught class constructor.
When the conditions are met then $pet will be an instance of PetPayload e.g.
Else $pet will be an instance of ErrorCollection e.g.
Advantages of use typed objects:
- Better static code analysis e.g. phpstan.
- Request payload in one place.
For maping objects Typed::object() have more precise type definition:
It is better for phpstan.
Class
ArrayOf
Source
Primitve field name can have characters that can't be used in method property name.
To solve this Source can be used.
Only
To not allow undefined fields Only can be used.
Callback
Factory
By default objects are build through __constructor and their propertires.
Alternative object can be build throught static factory method provided by Factory class attribute.
In above example the Factory attribute can be even: #[Factory].
If class is null then the context class is used.
method parameter is be default typed.
Method must be static. Must have one argument of type mixed. Must return the object or ErrorCollection.
Creating assert
Then add created assert attriute into property.
Others
Alnum, Alpha, ArrayKeyRegex, ArrayKeyString, ArrayLengthMax, ArrayLengthMin, ArrayValueLengthMax, ArrayValueLengthMin, ArrayValueString, Choice, Date, Digit, Email, LengthMax, LengthMin, Max, Min, NotBlank, Regex, Replace, ToBool, ToInt, ToString, Trim, TrimLeft, TrimRight,
Limitations
Object properties must have a specified type.
The type cannot be a union or intersection.
If incoming primitive data can have multiple types, use a mixed property.
In such cases, you can us a To* assert or a Callback.
