Description

Fractal provides a presentation and transformation layer for complex data output, the like found in RESTful APIs, and works really well with JSON. Think of this as a view layer for your JSON/YAML/etc.

When building an API it is common for people to just grab stuff from the database and pass it to json_encode(). This might be passable for "trivial" APIs but if they are in use by the public, or used by mobile applications then this will quickly lead to inconsistent output.

Fractal provides a presentation and transformation layer for complex data output, the like found in RESTful APIs, and works really well with JSON. Think of this as a view layer for your JSON/YAML/etc.

When building an API it is common for people to just grab stuff from the database and pass it to json_encode(). This might be passable for "trivial" APIs but if they are in use by the public, or used by mobile applications then this will quickly lead to inconsistent output.

Goals

  • Create a protective shield between source data and output, so schema changes do not affect users
  • Systematic type-casting of data, to avoid foreach()ing through and (bool)ing everything
  • Include (a.k.a embedding, nesting or side-loading) relationships for complex data structures
  • Work with standards like HAL and JSON-API but also allow custom serialization
  • Support the pagination of data results, for small and large data sets alike
  • Generally ease the subtle complexities of outputting data in a non-trivial API

This package is compliant with PSR-1, PSR-2 and PSR-4. If you notice compliance oversights, please send a patch via pull request.
