LanguageProject Introduction
Summary
A powerful command-line tool and library that automates the generation of API client libraries, server stubs, and documentation directly from an OpenAPI Specification (v2 or v3). It supports a large number of languages and frameworks, significantly accelerating API-related development.
Problem Solved
Manually writing API client/server code and documentation for multiple languages and frameworks is time-consuming, repetitive, and prone to inconsistencies. Maintaining these artifacts as the API evolves is also challenging, leading to potential desynchronization between the API specification and its implementations.
Core Features
Client SDK Generation
Automatically creates client libraries for various programming languages (Java, Python, JavaScript, C#, etc.) based on the OpenAPI Specification, allowing developers to quickly integrate with APIs.
Server Stub Generation
Generates server-side code templates or stubs for different frameworks and languages, providing a starting point for implementing API backends.
Documentation Generation
Produces human-readable API documentation in various formats (Markdown, HTML, etc.) directly from the OpenAPI Specification, ensuring documentation stays in sync with the API.
Supports OpenAPI Specs v2/v3
Supports both OpenAPI Specification v2 (formerly Swagger) and OpenAPI Specification v3, offering compatibility with a wide range of existing API specifications.

使用场景
该项目可广泛应用于任何需要基于OpenAPI规范进行自动化代码或文档生成的场景，尤其适用于：
快速构建API客户端
Details
开发者需要快速将一个第三方API集成到自己的应用中。使用OpenAPI Generator可以根据API的OpenAPI Spec生成目标语言的客户端库，直接使用而非手动编写网络请求代码。
User Value
显著节省开发时间，降低集成复杂性，减少因手动编写带来的潜在错误。
加速API后端开发
Details
后端团队基于一个已经设计好的OpenAPI Spec开始开发新的API服务。OpenAPI Generator可以生成该规范对应的服务器框架代码，帮助团队快速搭建服务基础结构。
User Value
缩短项目启动时间，提供一致的代码结构，允许开发者专注于业务逻辑而非底层通信细节。
自动化API文档生成与同步
Details
API维护者需要确保API文档与最新的API规范保持一致。OpenAPI Generator可以直接从Spec生成Markdown、HTML等格式的文档。
User Value
确保文档准确性和时效性，提升开发者体验，减少手动更新文档的负担。
