This package contains the official JSON Schemas for every version of Swagger/OpenAPI Specification:

• Swagger 1.2
• Swagger 2.0
• OpenAPI 3.0.x

All schemas are kept up-to-date with the latest official definitions via an automated CI/CD job. 🤖📦

You can install openapi-schemas via npm.

npm install openapi-schemas

The default export contains all OpenAPI Specification versions:

const openapi = require("openapi-schemas");

console.log(openapi.v1);    // { $schema, id, properties, definitions, ... }
console.log(openapi.v2);    // { $schema, id, properties, definitions, ... }
console.log(openapi.v3);    // { $schema, id, properties, definitions, ... }

Or you can import the specific version(s) that you need:

const { openapiV1, openapiV2, openapiV3 } = require("openapi-schemas");

console.log(openapiV1);    // { $schema, id, properties, definitions, ... }
console.log(openapiV2);    // { $schema, id, properties, definitions, ... }
console.log(openapiV3);    // { $schema, id, properties, definitions, ... }

You can use a JSON Schema validator such as Z-Schema or AJV to validate OpenAPI definitions against the specification.

const { openapiV3 } = require("openapi-schemas");
const ZSchema = require("z-schema");

// Create a ZSchema validator
let validator = new ZSchema();

// Validate an OpenAPI definition against the OpenAPI v3.0 specification
validator.validate(openapiDefinition, openapiV3);
