Validate a response according to an openapi schema.
- Performant.
- Extensively tested.
- Small footprint.
- Leverages jsonschema.
- Supports
$refin response schemas i.e.#/definitions/SomeType.
See ./test/data-driven/*.js for more examples.
var OpenAPIResponseValidator = require('openapi-response-validator');
var responseValidator = new OpenAPIResponseValidator({
responses: {
200: {
description: 'We found what you were looking for.',
schema: {
$ref: '#/definitions/ResourceResponse'
}
},
default: {
description: 'Something happened...',
schema: {
$ref: '#/definitions/SomeErrorResponse'
}
}
},

ResourceResponse: {
type: 'object',

}
},
required: ['id', 'name']
},
SomeErrorResponse: {
type: 'object',
properties: {
errorCode: {
type: 'string'
},
message: {
type: 'string'
}
}
}
}
});
var someResource = {};
var validationError = responseValidator.validateResponse(200, someResource);
/*

message: 'The response was not valid.',
errors: [

errorCode: 'type.openapi.responseValidation',
message: is not of a type(s) string'
