Install

``
npm install eov-handler-adapter
`

Usage

Create a signature for each api.
This may be generated with openapi-generator. See /samples/templates/apis.mustache

`typescript
type HelloApi = (args: { name: string; lang: string }) => {
text: string;
lang: string;
};
`

Define handlers along the signature.

`typescript
import { Handler, HandlerResponse } from "eov-handler-adapter";

const helloHandler: Handler = async ({ name, lang }) => {
return HandlerResponse.resolve({ text: こんにちは、${name}, lang }, 200);
};
`

Create routes with EOVHandlerAdapter.

`typescript
import {
EOVHandlerAdapter,
typeScriptNodeGenCoordinator,
} from "eov-handler-adapter";

// typeScriptNodeGenCoordinator matches parameter structure to typescript-node generator of openapi-generator
// You can also create custom coordinators.
const adapter = new EOVHandlerAdapter(typeScriptNodeGenCoordinator());

module.exports = {
hello: EOVHandlerAdapter.createController(helloHandler),
};
