Add a custom type definition file for an existing (non-typed) npm module, while automatically pick up the typing (for both Typescript or Javascript in case of VS Code). Typings are contained in the `typings/` directory

//real file is in: `typings/swagger-express-mw/index.d.ts` (relative to tsconfig.json)

import {Config, ConnectMiddleware} from "../swagger-node-runner"

/**
 * Create a new instance of Connect specific SwaggerNodeRunner
 */
export function create(config: Config, cb: {(err: Error | undefined, runner: ConnectMiddleware): void}): void
