swagger-client

What is swagger-client?

The swagger-client npm package is a JavaScript client for Swagger/OpenAPI specifications. It allows you to interact with APIs described by Swagger/OpenAPI documents, making it easier to consume and interact with RESTful services.

What are swagger-client's main functionalities?

Initialize Client

This feature allows you to initialize a Swagger client by providing the URL to the Swagger/OpenAPI specification. The client can then be used to interact with the API described by the specification.

const Swagger = require('swagger-client');
const client = new Swagger({ url: 'http://petstore.swagger.io/v2/swagger.json' });

Make API Calls

This feature allows you to make API calls using the initialized client. In this example, the client is used to call the 'getPetById' operation from the Petstore API.

client.then(client => {
  client.apis.pet.getPetById({ petId: 1 }).then(response => {
    console.log(response);
  });
});

Handle Authentication

This feature allows you to handle authentication by providing authorization details when initializing the client. In this example, an API key is provided for authentication.

const client = new Swagger({
  url: 'http://petstore.swagger.io/v2/swagger.json',
  authorizations: {
    api_key: new Swagger.ApiKeyAuthorization('api_key', 'YOUR_API_KEY', 'query')
  }
});

Other packages similar to swagger-client

axios

Axios is a promise-based HTTP client for the browser and Node.js. While it does not specifically target Swagger/OpenAPI specifications, it can be used to make HTTP requests to any API. Compared to swagger-client, axios is more general-purpose and does not provide built-in support for Swagger/OpenAPI documents.

openapi-client-axios

openapi-client-axios is a package that combines the capabilities of Axios with OpenAPI specifications. It allows you to generate an Axios client from an OpenAPI document, similar to swagger-client. However, it leverages Axios for making HTTP requests, providing a more flexible and widely-used HTTP client.

swagger-js

swagger-js is another JavaScript client for Swagger/OpenAPI specifications. It provides similar functionality to swagger-client, allowing you to interact with APIs described by Swagger/OpenAPI documents. The main difference is in the implementation and API design, but both packages serve the same purpose.

New!

This is the new version of swagger-js, 3.x. The new version supports Swagger 2.0 as well as OpenAPI 3.

For features known to be missing from 3.x please see the Graveyard.

For the older version of swagger-js, refer to the 2.x branch.

The npm package is called swagger-client and the GitHub repository is swagger-js. We'll be consolidating that soon. Just giving you the heads up. You may see references to both names.
