Fragment Types
You can infer specific fragments of an OpenAPI document by using some helpers from feTS.
Models
You can infer models from an OpenAPI document by using the OASModel type.
type OASModel<TOASDocument extends OpenAPI.Document, TModelName extends string>Example
import { Mutable, OASModel } from 'fets'
import type oas from './openapi'
// This will infer `User` from `components.schemas.User`
type User = OASModel<Mutable<typeof oas>, 'User'>Request Parameters
You can infer request body from an OpenAPI document by using the OASRequestBody type.
type OASRequestBody<TOASDocument extends OpenAPI.Document, TPath extends string, TMethod extends HTTPMethod>Example
import { Mutable, OASRequestParameters } from 'fets'
import type oas from './openapi'
type AddUserInput = OASRequestParams<Mutable<typeof oas>, '/user', 'POST'>Response body
You can infer response body from an OpenAPI document by using the OASResponseBody type.
type OASResponseBody<TOASDocument extends OpenAPI.Document, TPath extends string, TMethod extends HTTPMethod, TStatusCode extends StatusCode>Example
user-response-body
import { Mutable, OASResponseBody } from 'fets'
import type oas from './openapi'
type UserByIdResponse = OASResponseBody<Mutable<typeof oas>, '/user/:id', 'POST', 200>
