Expand-to

Tools for transforming JSON-schema models into dev/build/test/run-time application tools

Features

• belongsTo → nests one resource inside another
• hasMany → adds routes for one-to-many relationships
• hasMany + as → adds routes for polymorphic one-to-many relationships
• name: user + hasMany → a nested a copy of hasMany routes are added to the user resource for accessing via the users' implicit identity
• treeOf → adds routes for accessing and mutating a hierarchical resource
• immutable: true → omits methods that would mutate the resource
• versioned: true → adds routes for listing, accessing, and restoring versioned entities (TODO)
• undeletable: true → adds routes for listing, accessing, and undeleting soft deleted entities (TODO)

Examples

API

A single low level function is provided to tranform a spec into a raw description of the resources and models. Usually this will not be called directly.

• expandToResources(spec, config = {}) → { paths, models }

The most common use case is to use the following functions that take a spec and an optional config and return an object that is useful to your application.

• expandToOperations(spec, config = {}) → { paths, models, operations }
• expandToOpenApi(spec, config = {}) → openApiSpec
• expandToValidations(spec, config = {}) → { paths, models, operations, validations }
• expandToTestData(spec, config = {}) → (operationName) → testData

Alternatively each core API function exposes a lower level function that can be used to compose your own custom tranformations.

• expandToOpenApi({ operations, models }, config = {}) → { models, operations, spec }
• expandToOperations({ paths, models }, config = {}) → { paths, models, operations }
• expandToValidations({ operations, models }, config = {}) → { paths, models, operations, validations }
• expandToTestData({ operations, models }, config = {}) → { paths, models, operations, testData }
