This is a catch all for the multiple requests to update the type definition. Needs to be done for the next release.

axios.d.ts

declare var axios: axios.AxiosStatic
declare module axios {
  interface AxiosRequestMethods {
    get(url: string, config?: any): axios.Promise;
    delete(url: string, config?: any): axios.Promise;

    patch(url: string, data: any, config?: any): axios.Promise;
  }
  interface AxiosStatic extends AxiosRequestMethods {
    (options: axios.RequestOptions): axios.Promise;
    create(defaultOptions?: axios.InstanceOptions): AxiosInstance;
    all(iterable: any): axios.Promise;
    spread(callback: any): axios.Promise;
  }
