## What it is
Swagger Client is a JavaScript library for fetching, resolving, and executing requests against Swagger/OpenAPI-defined REST APIs from the browser or Node.js. It parses OpenAPI 2.0, 3.0, 3.1, and 3.2 documents and turns them into callable client operations.

## Use cases
- call a REST API from an OpenAPI spec in JavaScript
- fetch and resolve a swagger/openapi document in node
- generate an api client from an openapi 3.1 definition
- execute swagger-defined operations in the browser
- validate and dereference an openapi spec programmatically

## When to choose
- you have an OpenAPI/Swagger spec and want to call the API without hand-writing HTTP code
- you need to parse, resolve, or validate OpenAPI documents in JS
- you need a client that works in both browser and Node.js

## When to avoid
- your API has no OpenAPI/Swagger definition
- you need a code-generating SDK for other languages (use Swagger Codegen)
- you only need interactive API docs UI (use Swagger UI)
