Schema Validator

Schema Validator is a module that allows validate endpoints against a local schema.
The schema must be a JSON in OpenAPI 3.0
The file must be located in path/to/root/schemas/build/public.json.
The endpoints will be validated in paths by endpoint and verb.

Installation

npm install @janiscommerce/schema-validator

API

• new SchemaValidator( endpoint, [ verb ] )
  Constructs de Validator.
  Validates the verb format and to be included in ['get', 'put', 'post', 'patch', 'delete', 'options'].
  In case that the verb is not valid, will throw a SchemaValidatorError.

• validate()
  Validates endpoint and verb exists in schema paths.

• shouldValidateClient()
  Determinates if the endpoint should validate client.
  To configure this, you can add an optional field x-validate-client: Boolean in schema.paths[myEndpoint][myVerb]

• shouldValidateLogged()
  Determinates if the endpoint should validate logged.
  To configure this, you can add an optional field x-validate-logged: Boolean in schema.paths[myEndpoint][myVerb]

Errors

The errors are informed with a SchemaValidatorError.
This object has a code that can be useful for a correct error handling.
The codes are the following:

|Code |Description | |-----|-----------------------------| |1 |Invalid verb | |2 |Schema not found | |3 |Invalid paths in schema | |4 |Endpoint not found | |5 |Verb not found for endpoint |

Usage

const SchemaValidator = require('@janiscommerce/schema-validator');

const schemaValidatorValid = new SchemaValidator('api/valid-endpoint'); // default verb: 'get'

schemaValidatorValid.validate(); // expected output: true

const schemaValidatorInvalid = new SchemaValidator('api/invalid-endpoint', 'post');

schemaValidatorInvalid.validate(); // throws a SchemaValidatorError: Endpoint not found in schema.paths
