AelasticS Types
Types dynamically created at run time - 0.x.x-Alpha version
- Arbitrarily data structures - supported both tree and graph recursive/cyclic structures
- Data validation and serialization/deserialization
- Map-reduce processing and general traversals
Highlights
Types and Type schemas
-
Simple types (number, string, boolean, literal and user defined semantic domains/types)
-
Complex types (object types, subtypes, array, map, date type, union, tagged union, intersection)
-
Special types (optional, object reference, link)
-
Recursive/cyclic types
-
Type schemas as containers of type definitions to manage complexity
-
Special meta-type operators to deduce Typescript type declarations used for typechecking by compiler
-
Intellisence in code editors (similar to React prop-types library)
Validation
- Lot of predefined chainable operators for constraining string and number values
- User supplied validate functions for specifying value constrains on arbitrarily complex types
- User defined error message specifications for violated constrains
- Extensive error reports collected during data validations
Serialization/Deserialization
- Graph cyclic data structures are transformed to/from Data Transfer Objects (JSON tree data structures)
- Inheritance (subtyping) supported
- Graph cyclic data structures are supported as an out-of-the-box feature
- No decorators/annotations are needed
- Support for types not supported by JSON such as maps, unions, dates, object references, etc.
Structure Traversal/Processing
- General traversal of graph cyclic structures in a depth-first or bread-first manner
- Map and Reduce processing of graph cyclic structures, a generalization of the well-known Map/Reduce processing of arrays and lists
- Both type and instance level traversals/processing are supported
