Documentation

The Document type represents the top-level JSON-API requirement.

data attribute - the resulting JSON may be either a singleton resource or a list of resources. See Resource for the construction.

For more information see: http://jsonapi.org/format/#document-top-level

The Resource type encapsulates the underlying Resource

Included in the top-level Document, the Resource may be either a singleton resource or a list.

For more information see: http://jsonapi.org/format/#document-top-level

The ErrorDocument type represents the alternative form of the top-level JSON-API requirement.

error attribute - a descriptive object encapsulating application-specific error detail.

For more information see: http://jsonapi.org/format/#errors

The Included type is an abstraction used to constrain the included section of the Document to JSON serializable Resource objects while enabling a heterogeneous list of Resource types.

No data constructors for this type are exported as we need to constrain the Value to a heterogeneous list of Resource types. See mkIncludedResource for creating Included types.

Type for providing application-specific detail to unsuccessful API responses.

Specification: http://jsonapi.org/format/#error-objects

We can specify limits on the number of rows we would like back from the database

A type representing the Relationship between 2 entities

A Relationship provides basic information for fetching further information about a related resource.

Specification: http://jsonapi.org/format/#document-resource-object-relationships

Type representing a JSON-API resource object.

A Resource supplies standardized data and metadata about a resource.

Specification: http://jsonapi.org/format/#document-resource-objects

A typeclass for decorating an entity with JSON API properties

Typeclass indicating how to access an Identifier for a given datatype

Identifiers are used to encapsulate the minimum amount of information to uniquely identify a resource.

This object will be found at multiple levels of the JSON-API structure

Specification: http://jsonapi.org/format/#document-resource-identifier-objects

Type representing a JSON-API link object.

Links are an abstraction around an underlying Map consisting of relevance identifiers as keys and URIs as values.

Example JSON: "links": { "self": "http://example.com/posts/1" }

Specification: http://jsonapi.org/format/#document-links

Type representing a JSON-API meta object.

Meta is an abstraction around an underlying Map consisting of resource-specific metadata.

Example JSON: "meta": { "copyright": "Copyright 2015 Example Corp.", "authors": [ "Andre Dawson", "Kirby Puckett", "Don Mattingly", "Ozzie Guillen" ] }

Specification: http://jsonapi.org/format/#document-meta

Convienience class for constructing a Meta type

Example usage: @ data Pagination = Pagination { currentPage :: Int , totalPages :: Int } deriving (Show, Generic)

instance ToJSON Pagination instance MetaObject Pagination where typeName _ = "pagination" @

Pagination is arguably a meta object not covered by the Spec. The spec instead opts for links which are supported by this library. However if you would like to throw a generic Pagination meta object into your response payload this type may be used.

Constructor function for building Links

Helper function to beuild relative links for a collection of resources of type ResourceEntity.

This helper function assumes that the first page is always page 0.

Constructor function for creating a Relationship record

A relationship must contain either an Identifier or a Links record

Helper function to build relative links for a single resource of type ResourceEntity

Constructor function for the Document data type.

See mkCompoundDocument for constructing compound Document including 'side-loaded' resources

Constructor function for the Document data type. See mkIncludedResource for constructing the Included type.

Supports building compound documents http://jsonapi.org/format/#document-compound-documents

Constructor function for the Document data type.

Supports building compound documents http://jsonapi.org/format/#document-compound-documents

Convienience constructor function for the Meta type

Useful on its own or in combination with Meta's monoid instance

Example usage: See MetaSpec.hs for an example
