OpenAPI Specification Schemas

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

Version	Schema	Docs
Swagger 1.2	v1.2 schema	v1.2 docs
Swagger 2.0	v2.0 schema	v2.0 docs
OpenAPI 3.0.x	v3.0.x schema	v3.0.3 docs
OpenAPI 3.1.x	v3.1.x schema	v3.1.0 docs

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

Installation

You can install OpenAPI Schemas via npm.

npm install @apidevtools/openapi-schemas

Usage

The default export contains all OpenAPI Specification versions:

const openapi = require("@apidevtools/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, ... }
console.log(openapi.v31);    // { $schema, id, properties, definitions, ... }

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

const { openapiV1, openapiV2, openapiV3, openapiV31 } = require("@apidevtools/openapi-schemas");

console.log(openapiV1);    // { $schema, id, properties, definitions, ... }
console.log(openapiV2);    // { $schema, id, properties, definitions, ... }
console.log(openapiV3);    // { $schema, id, properties, definitions, ... }
console.log(openapiV31);    // { $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 { openapiV31 } = require("@apidevtools/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, openapiV31);
