Validate request properties against an OpenAPI spec.
npm install @leoscope/openapi-request-validator* Performant.
* Extensively tested.
* Small footprint.
* Does not validate parameter input. Converts parameter input to jsonschema using openapi-jsonschema-parameters.
* Leverages jsonschema.
* Supports $ref in body schemas i.e. #/definitions/SomeType.
* Does not supply default values (use openapi-default-setter).
* Does not handle type coercion (use openapi-request-coercer).
See ./test/data-driven/*.js for more examples.

`
An array of openapi parameters.
#### args.schemas
If given as an array, each schema must have an id property. See ./test/data-driven/schemas
for tests with . Ids may be schema local (i.e. #/definitions/SomeType),/SomeType
or URL based (i.e. ). When supplied, $ref usage will map exactly to theid
Id e.g. if is /SomeType, $ref must be /SomeType.
If given as an object, it will be assigned to bodySchema.definitions. Schemas may then be dereferenced in parameters by using #/definitions/.
#### args.version
An optional string that currently does nothing. This will ensure nothing breaks
for new versions of openapi drafts that get added in the future.
#### args.errorTransformer
A function that transforms errors.
This function is passed 2 arguments.
``
errorTransformer: function(openapiError, ajvError) {
return {
message: openapiError.message
};
}
See the error format in ajv for
ajvError. openapiErrors have the following properties:
* errorCode - A jsonschema error suffixed with .openapi.requestValidation.location
* - One of body, headers, path, or query. Signifies where validationmessage
failed.
* - A detailed message as to why validation failed.path
* - The property of the location that failed validation.
#### args.customFormats
An object of formatters to use for the format keyword.
See Custom Formats in jsonschema.
