We have some more public methods on app.

  • app.render(req, res, pathname: string, query: any)
  • app.renderToHTML(req, res, pathname, query)
  • app.renderError(err, req, res, pathname, query)
  • app.renderErrorToHTML(err, req, res, pathname, query)

@nkzawa Thank you for your notice!
I wrote those types along with README.md and read codes a bit, but I lost them. (It looks not documented yet.) Anyway I add them.

I added them and getRequestHandler for custom-handler. For https://github.com/zeit/next.js/blob/master/examples/custom-server/server.js#L7

getRequestHandler(): any;
render(req: any, res: any, pathname: string, query: any): any;
renderToHTML(req: any, res: any, pathname: string, query: string): string;
renderError(err: Error, req: any, res: any, pathname: any, query: any): any;
renderErrorToHTML(err: Error, req: any, res: any, pathname: string, query: any): string;
};
declare module.exports: (...opts: any) => NextApp
}

declare module "next/head" {
declare module.exports: Class<React$Component<void, any, any>>;
}

declare module "next/link" {
declare module.exports: Class<React$Component<void, {href: string}, any>>;
}

declare module "next/prefetch" {
declare export var prefetch: (url: string) => any;
declare export var reloadIfPrefetched: any;
declare export default Class<React$Component<void, {href: string, prefetch?: boolean}, any>>;
}

declare module "next/router" {
declare module.exports: {
route: string;
pathname: string;
query: Object;
onRouteChangeStart: ?((url: string) => void);
onRouteChangeComplete: ?((url: string) => void);
onRouteChangeError: ?((err: Error & {cancelled: boolean}, url: string) => void);
push(url: string, as: ?string): Promise<boolean>;
replace(url: string, as: ?string): Promise<boolean>;
};
}

declare module "next/document" {
declare export var Head: Class<React$Component<void, any, any>>;
declare export var Main: Class<React$Component<void, any, any>>;
declare export var NextScript: Class<React$Component<void, any, any>>;
declare export default Class<React$Component<void, any, any>> & {
getInitialProps: (ctx: {pathname: string, query: any, req?: any, res?: any, xhr?: any, err?: any}) => Promise<any>;
renderPage(cb: Function): void;
};
}
