rails-api/active_model_serializers

Features

• Model to JSON Conversion - Transforms model objects into structured JSON representations for API responses using a customizable process.
• Response Formatting - Transforms database models into structured JSON responses for web APIs using a customizable serialization process.
• Serialization Contexts - Passes an authorization context into the serializer to customize output based on user permissions.
• Authorization-Based - Controls which data fields are visible in a response based on the current user identity or authorization level.
• Nested Serialization - Automatically embeds related database records into API responses by recursively applying serializers.
• Association Definitions - Provides a descriptive language to specify how related models are included and represented in the JSON output.
• Attribute-Based Access Control - Controls which attributes and associations appear in the output based on the current authorization context.
• Serialization Attribute Restrictions - Restricts specific attributes and associations based on the current user identity or authorization level.
• Class Instance JSON Serializers - Transforms model or plain Ruby objects into JSON representations using dedicated serializer classes.
• Adapter-Based Output Formatting - Uses a pluggable adapter pattern to transform internal data structures into specific JSON specifications.
• Computed Properties - Allows the definition of synthetic properties via custom logic within serializer methods.
• Attribute-Mapping Layer - Decouples the external API contract from the internal database schema by mapping model attributes to custom keys.
• Contextual Serialization Logic - Passes external context into the serialization process to filter attributes or associations based on user permissions.
• Model-to-JSON Mappers - Decouples database schemas from API contracts by mapping internal attributes to custom JSON keys.
• Specification Adapters - Uses a pluggable adapter pattern to format JSON responses according to specific API specifications.
• Attribute Key Mapping - Decouples the external API contract from the database schema by mapping internal attributes to custom JSON keys.
• Specification Adapters - Provides a formatting layer that organizes serialized data to follow specific standards like the JSON API specification.
• JSON APIs - Builds API endpoints that adhere to specific data standards using pluggable adapters.
• JSON Structure Adapters - Adjusts the output structure using adapters to satisfy specific API standards or root key requirements.
• Rails JSON Serializers - Transforms Ruby on Rails model objects and associations into structured JSON responses for APIs.
• Relationship Mapping - Defines how associated models are linked or embedded in JSON outputs to manage payload size.
• Resource Sideloading - Flattens associated data into a separate root-level collection to avoid deep nesting and reduce payload duplication.
• Response Formatters - Adds pagination metadata and authorization-based filtering to Rails controller responses.
• API Response Optimizations - Reduces server load by caching serialized JSON data and monitoring conversion metrics.
• Serialized Output Caching - Stores serialized object results as JSON to reduce computation time for repeat requests.
• Fragment Caches - Provides fragment caching to store specific serialized object outputs and bypass redundant computation for repeat requests.
• Resource Serialization Formats - Processes collections of resources by applying specific serializers to each item in the group.
• Casing Transformers - Implements global and class-level formatting rules to convert attribute keys into specific casing styles.
• Object Serialization - Applies consistent serialization behavior to non-database plain Ruby objects for uniform API responses.
• Computed Attribute Derivation - Allows the definition of virtual attributes that are computed via custom logic during serialization.
• Associated Data Sideloading - Implements sideloading of associated records to simplify client-side parsing and reduce payload duplication.
• Association ID Embedding - Provides the ability to embed only identifiers for associated objects to minimize response size.
• Document Structure Control - Controls the final structure of the JSON response, allowing for flat lists or specific specification layouts.
