Koa Method Override Middleware

koa-override is a Koa middleware designed to enable clients to utilize HTTP verbs like PUT or DELETE in environments where direct support is limited, typically by overriding the method via a `_method` field in the request body or an `X-HTTP-Method-Override` header. The current stable version is 4.0.0, released in June 2024. This package is maintained by the Egg.js team, indicating active development and stability within the Koa ecosystem. It provides a simple API, `override([options])`, allowing configuration of allowed override methods (defaulting to `POST` requests). A key differentiator is its explicit method overriding mechanism, making it a robust solution for RESTful API compatibility challenges with legacy clients or specific network constraints. It ships with TypeScript types and supports both CommonJS and ES Modules since version 4.0.0.
