Felicity is a framework that allows you to expose your functional F# domain logic as an API following the JSON:API specification, with no boilerplate.
This framework contains over 1,000 end-to-end tests checking success-path and error-path functionality of all operations.
This is free and open source software.
Key Features
- Based on ASP.NET Core and Giraffe.
- Thoroughly tested.
- Highly succinct, declarative and discoverable fluent-style syntax.
- Designed for with idiomatic, immutable F# domain logic, including DU wrappers and smart constructors.
- Automatic support for sparse fieldsets and included resources.
- Automatic routing and link generation for resources and relationships.
- Any attribute, relationship, or operation may be async or return errors.
- Loads included resources on-demand and in parallel.
- Easily pass strongly typed context data (e.g. authentication information) through Felicity to any part of your code.
- Over 100 common error cases handled automatically; you only have to care about your application-specific errors.
- If it compiles and starts, it works.
- Support for polymorphic resource collections and relationships.
- Built-in support for resource-level precondition validation using ETags and modification dates .(requiring the client to supply If-Match and If-Unmodified-Since to avoid “mid-air collisions”).
- Resource-level locking and operation queueing to ensure thread safety (can also lock “parent” resources and plug into external locking mechanisms).
- Supports sideposting (a.k.a. sideloading) to create a related resource hierarchy in a single POST request (not in official JSON:API spec).
